## Title
System and method for wideband audio communication with a quick service restaurant drive-through intercom

## Abstract

This disclosure relates to a quick service restaurant intercom communication system. The system is configured such that communication between a customer and a staff member is accomplished in wideband audio. Intercom communication systems that utilize narrow band audio for communication between drive-through customers and staff members may be considered “good enough”. However, the low fidelity sound produced by narrow band audio systems often results in misunderstandings between customers and staff members, a high amount of background noise during communication, and/or other negative effects. Wideband audio may facilitate clearer communication between customers and staff members. Wideband audio communication may be costlier and/or more complicated to implement, but may result in increased staff efficiency and/or increased customer satisfaction. In some implementations, the system may include an audio order placement sub-system, a base station, an order entry device, a mounting mechanism, and/or other components.

Quick service restaurant intercom communication systems typically facilitate communication between a customer outside the quick service restaurant and a staff member inside the quick service restaurant. Conventionally, quick service restaurant intercom communication systems utilize narrowband audio.
SUMMARY
One aspect of the disclosure relates to a quick service restaurant intercom communication system. The quick service restaurant intercom communication system is configured such that communication between drive-through customers and staff members is accomplished in wideband audio. In some implementations, the system may include an audio order placement sub-system that may be positionally associated with a menu board and/or a speaker post, a base station, an audio order receiving sub-system, and/or other components. In some implementations, the audio order placement sub-system may be the menu board and/or the speaker post.
A quick service restaurant may include a kitchen, a drive-through, and/or other components. The quick service restaurant may be configured to serve drive-through and/or walk in customers. The kitchen may include a kitchen display system, and/or other components. A menu board, a speaker post, the audio order placement sub-system, the base station, the audio order receiving sub-system, a drive through lane, and/or other devices may be associated with the drive-through. The audio order receiving sub-system may be configured to be worn by a staff member associated with the drive-through lane. The staff member may enter orders from drive-through customers into an order entry device and/or other devices. Customers may place orders at ordering stations operated by staff members within the restaurant and/or in the drive-through lane at the audio order placement sub-system. Orders may be displayed to staff members preparing the orders via the kitchen display system, for example. Staff members of the quick service restaurant may prepare the orders while the customers wait at the ordering stations, in the drive-through lane, and/or at other locations. Preparing the orders may include cooking and/or otherwise assembling the orders in the kitchen and/or other areas of the quick service restaurant.
The audio order placement sub-system may be configured to receive voice sound indicating orders from customers and facilitate communication between the customers and staff members. The audio order placement sub-system may be positionally associated with the menu board and/or the speaker post. In some implementations, the audio order placement sub-system may include one or more of a first microphone, a first speaker, and/or other components. In some implementations, the first microphone may include an array of microphones (e.g., an array microphone). The first speaker may include an array of speakers. The first microphone, the first speaker and/or other components of the audio order placement sub-system may be mounted within and/or near the menu board and/or the speaker post. In some implementations, the components of the audio order placement sub-system (e.g., first microphone, first speaker) may be mounted separately. For example, the first microphone and the first speaker may be mounted in separate enclosures within the menu board and/or the speaker post. The first microphone may be configured to receive sound from a customer placing an order at or near the menu board and to generate wideband order information signals that represent the received sound. The first speaker may be configured to receive wideband order information signals and to generate sound represented in the received wideband order information signals. The first speaker may be configured to generate the sound such that the sound is audible to a customer at or near the menu board and/or the speaker post.
The base station may be configured to communicate with the audio order placement sub-system and one or more audio order receiving sub-systems wirelessly and/or via wires. In some implementations, the base station may include one or more of a first transceiver, a first signal processor, and/or other components. The first transceiver may be configured to transmit and receive encoded audio communication signals. The encoded audio communication signals may be transmitted to the audio order receiving sub-system and received from the audio order receiving sub-system, for example. In some implementations, the first transceiver may be configured to transmit and receive encoded audio communication signals substantially simultaneously. The first signal processor may be configured to encode wideband order information signals received from the first microphone into encoded audio communication signals for transmission by the first transceiver. The first signal processor may be configured to decode encoded audio communication signals received by the first transceiver into wideband order information signals for the first speaker.

DETAILED DESCRIPTION
FIG. 1 illustrates a quick service restaurant intercom communication system 10. Quick service restaurant intercom communication system 10 may be configured such that communication between drive-through customers and staff members is accomplished in wideband audio. Intercom communication systems that utilize narrowband audio for communication between drive-through customers and staff members may be considered “good enough”. However, the low fidelity sound produced by narrowband audio systems often results in misunderstandings between customers and staff members, and/or other negative effects. These negative effects may decrease customer satisfaction with a quick service restaurant as a whole.
In system 10, wideband audio may facilitate clearer communication between customers and staff members. The clearer communication facilitated by wideband audio may be particularly advantageous in quick service restaurant settings because quick service restaurants are typically located on busy streets and/or highways. Background noise from the surrounding area and/or engine noise from vehicles in the drive-through may be substantial. Quick service restaurant staff members who serve drive-through customers for an extended period of time may benefit from clearer communication, reduced listening effort, and reduced fatigue facilitated by wideband audio. Wideband audio communication may be costlier and/or more complicated to implement, but may result in increased staff efficiency and/or increased customer satisfaction. The increased staff efficiency and/or increased customer satisfaction may result from higher quality speech heard by both customers and staff members. For customers and/or staff members, wideband audio may improve intelligibility in the presence of the background noise described above. Wideband audio may facilitate a clearer understanding of accented speakers, make it easier to understand two people speaking at the same time, make it easier to hear people with soft voices, reduce listening effort, facilitate distinguishing different but similar sounds, and/or result in other advantages. For example, quick service restaurant staff members stationed at the drive-through may feel less fatigued after multiple intercom communications with multiple customers because of the reduced listening effort facilitated by wideband audio. As another example, order accuracy may go up because customers and staff members may communicate more clearly in the presence of background noise. The customer experience may be improved because the communication between customers and staff members may be more natural. Customer loyalty may increase as a result of the advantages of wideband audio. In some implementations, system 10 may include one or more of an audio order placement sub-system 22, a base station 23, an audio order receiving sub-system 24, and/or other components.
The description herein of system 10 in connection with a quick service restaurant is not intended to be limiting. Wideband audio intercom communication systems like system 10 may be beneficial in other applications such as drive-through pharmacies, drive-through banking, customer service booths (e.g., at movie theaters, theme parks, concert halls, zoos), and/or other applications.
As shown in FIG. 1, a quick service restaurant 12 may include a kitchen 14, a drive-through lane 16, and/or other components. Quick service restaurant 12 may be configured to serve drive-through and/or walk in customers. Kitchen 14 may include a kitchen display system 18, and/or other components. A menu board 20, a speaker post 21, audio order placement sub-system 22, base station 23, audio order receiving sub-system 24, and/or other devices may be associated with drive-through lane 16. Audio order receiving sub-system 24 may be configured to be worn by a staff member 28 associated with drive-through lane 16. Staff member 28 may enter orders from drive-through customers into an order entry device 30 (e.g., a point of sale (POS) terminal) and/or other devices. The orders may be received by a central POS system via the POS terminal which then sends the necessary information to kitchen display system 18. Customers may place orders at ordering stations operated by staff members within the restaurant and/or in drive-through lane 16 at menu board 20 and/or speaker post 21 via audio order placement sub-system 22. Orders may be displayed to staff members preparing the orders via kitchen display system 18, for example. Staff members of the quick service restaurant may prepare the orders while the customers wait at the ordering stations, in drive-through lane 16, and/or at other locations. Preparing the orders may include cooking and/or otherwise assembling the orders in kitchen 14 and/or other areas of quick service restaurant 12.
Kitchen display system 18 may be configured to receive order information from order entry device 30 and display order state information related to the food orders in kitchen 14. Order information may include for example, food and/or beverage items from the menu board, quantities associated with the food and/or beverage items, pricing information such as coupon discounts, and/or other information. The order state information may comprise information related to the current preparation of the food order. For example, order state information may include information indicating that an order is in the process of being assembled and/or information indicating that an order has been completed and/or delivered to a customer. The order state information may be displayed by kitchen display system 18 such that kitchen staff may prepare the customer orders and track the progress (e.g., state to state) through kitchen 14. Kitchen display system 18 may include multiple displays wherein individual ones of the displays show slightly different information compared to the other displays. For example, a display may be tailored for a particular state of food preparation. In some implementations, kitchen display system 18 may include a kitchen video system (KVS).
Drive-through lane 16 may be located adjacent to and/or near quick service restaurant 12. Drive-through lane 16 may be configured such that customers driving vehicles through drive-through lane 16 may access one or more of menu board 20, speaker post 21, audio order placement sub-system 22, a payment and/or pickup window, and/or other components of quick service restaurant 12. The payment and/or pickup window may be a window in quick service restaurant 12 operated by staff members through which customers in drive-through lane 16 may pay for and/or pick up their orders without leaving their vehicles.
Menu board 20 may be located at and/or near drive-through lane 16 in proximity to quick service restaurant 12. Menu board 20 may be configured to display menu items offered by quick service restaurant 12 to customers in drive-through lane 16. In some implementations, menu board 20 may include static printed materials, digital signage, and/or other signage. Digital signage may allow menu board 20 to be changed by employees of quick service restaurant 12 and/or other people. Menu board 20 may allow customers to view menu items from drive-through lane 16 of quick service restaurant 12. Menu board 20 may be configured to house audio order placement sub-system 22, and/or one or more components of audio order placement sub-system 22. In some implementations, menu board 20 may be audio order placement sub-system 22.
Speaker post 21 may be located at and/or near drive-through lane 16 in proximity to quick service restaurant 12 and menu board 20. Speaker post 21 may comprise a physical object (e.g., a post) configured to contain components (e.g., audio order placement sub-system 22) configured to facilitate communication between customers and staff members of the quick service restaurant. Speaker post 21 may be configured with any form factor such that audio order placement sub-system 22 is accessible to drivers in drive-through lane 16 to facilitate communication between customers placing orders while sitting in their vehicles and staff members. Speaker post 21 may be configured to house audio order placement sub-system 22, and/or one or more components of audio order placement sub-system 22. In some implementations, speaker post 21 may be audio order placement sub-system 22.
Audio order placement sub-system 22 may be configured to receive voice sound indicating orders from customers and facilitate communication between the customers and staff members (e.g., staff member 28) via base station 23, audio order receiving sub-system 24, and/or other components of system 10. Audio order placement sub-system 22 may be positionally associated with menu board 20 and/or speaker post 21. In some implementations, audio order placement sub-system 22 may include one or more of a microphone, a speaker, and/or other components. The microphone, the speaker and/or other components of audio order placement sub-system 22 may be mounted within and/or near menu board 20 and/or speaker post 21. In some implementations, the components of audio order placement sub-system 22 (e.g., microphone, speaker) may be mounted separately. For example, the first microphone and the first speaker may be mounted in separate enclosures within the menu board and/or the speaker post. In some implementations, audio order placement sub-system 22 may be an entity separate from menu board 20. In some implementations audio order placement sub-system 22 may form an order point separate from menu board 20 that does not include a speaker post (e.g., speaker post 21).
Audio order placement sub-system 22 and/or the components (e.g., speaker, microphone) of audio order placement sub-system 22 may be mounted with one or more mechanical devices configured to hold the components of audio order placement sub-system 22, and/or audio order placement sub-system 22 within and/or near menu board 20 and/or speaker post 21. Holding may include supporting the weight of the components of audio order placement sub-system 22, coupling the components of audio order placement sub-system 22 to menu board 20 and/or speaker post 21, and/or other actions. For example, the mechanical devices may include one or more screws, brackets, hooks, cantilevers, suction devices, hinges, pins, sleeves, joints, chassis, slots, foam blocks, and/or other mechanical devices.
FIG. 2 illustrates components of audio order placement sub-system 22. In some implementations, audio order placement sub-system 22 may include one or more of a microphone 34, a speaker 36, and/or other components. Microphone 34 may be configured to receive sound from a customer 32 placing an order at or near a menu board (e.g., menu board 20 shown in FIG. 1) and to generate wideband order information signals that represent the received sound. The received sound may be in the wideband frequency range. The received sound may include sound communicating food and/or beverage items from the menu board, quantities associated with the food and/or beverage items, special preparation requirements (e.g., no onions), and/or other information. In some implementations, microphone 34 may include an array of microphones (e.g., an array microphone). In some implementations, microphone 34 may be associated with an analog to digital converter configured to digitize the received sound.
Speaker 36 may be configured to receive wideband order information signals and to generate sound represented in the received wideband order information signals. In some implementations, speaker 36 may include an array of speakers. Speaker 36 may be configured to generate the sound such that the sound is audible to a customer 32 at or near the menu board. For example, the sound represented in the received wideband order information signals may be the voice of staff member 28 responding to customer 32. In some implementations, speaker 36 may be associated with a digital to analog converter configured to generate analog audio for speaker 36.
Returning to FIG. 1, base station 23 may be configured to facilitate wideband audio communication between customers and staff members via audio order placement sub-system 22, audio order receiving sub-system 24, and/or other components of system 10. Base station 23 may be configured to communicate with audio order placement sub-system 22 and one or more audio order entry receiving sub-systems 24 wirelessly and/or via wires.
FIG. 2 illustrates components of base station 23. In some implementations, base station 23 may include one or more of a transceiver 38, a signal processor 43, and/or other components. Transceiver 38 may be configured to transmit and receive encoded audio communication signals. The encoded audio communication signals may be transmitted to audio order receiving sub-system 24 and received from audio order receiving sub-system 24, for example. In some implementations, the encoded audio communication signals may be transmitted and/or received wirelessly and/or via wires. In some implementations, transceiver 38 may be configured to transmit and receive the encoded audio communication signals via one or more radio channels of a radio link. In some implementations, transceiver 38 may be configured to transmit and receive encoded audio communication signals substantially simultaneously.
In some implementations, a communication protocol associated with transceiver 38 may be configured for narrow-band audio. The communication protocol may specify a number of bits per frame. For example, the communication protocol may specify 320 bits per frame.
Signal processor 43 may be configured to encode and/or compress wideband order information signals received from microphone 34 into encoded audio communication signals for transmission by transceiver 38. Signal processor 43 may be configured to decode and/or decompress encoded audio communication signals received by transceiver 38 into wideband order information signals for speaker 36. In some implementations, signal processor 43 may include one or more individual processing units. In some implementations, signal processor 43 may be configured to provide wideband noise suppression and/or acoustic echo cancellation (e.g., for the sound received by microphone 34). In some implementations, signal processor 43 may perform digital audio data rate compression and/or decompression. In some implementations, signal processor 43 may perform digital audio data rate compression such that the encoded audio communication signals transmitted by transceiver 38 fit in the same radio data stream occupied by narrowband audio. In some implementations, an encoding and/or compression format may be associated with signal processor 43 such that the wideband order information signals may be compressed into frames having a number of bits per frame that is based on the communication protocol associated with transceiver 38 (e.g., 320 bits per frame).
In some implementations, signal processor 43 may provide up to about 8:1 data compression. In some implementations, signal processor 43 may provide data compression according to an algorithm such as BV32. In some implementations, signal processor 43 may provide less than 8:1 data compression. For example, signal processor 43 may provide less than 8:1 data compression when the transmitted signals occupy more than one time slot (e.g., for digital radios that use time division multiplexing).
Signal processor 43 in base station 23 may include two separate digital signal processors with one digital signal processor performing wideband acoustic echo cancellation and noise suppression, and the second digital signal processor performing the data compression encoding and decoding (e.g., encoding and/or decoding depending on whether communication is from a customer to a staff member or from a staff member to a customer). In some implementations, digital signal processor 43 may be integrated with transceiver 38 as a single component of base station 23.
Audio order receiving sub-system 24 may be configured to receive voice communication (e.g., sound) from staff member 28 and facilitate communication between customer 32 and staff member 28 via base station 23, audio order placement sub-system 22, and/or other components of system 10. In some implementations, audio order receiving sub-system 24 may be configured to be worn by a staff member. In some implementations, audio order receiving sub-system 24 may be configured to be worn as one or more of a headset, a belt, an armband, an earpiece, and/or other devices. Audio order receiving sub-system 24 may be located remotely from audio order placement sub-system 22. Audio order receiving sub-system 24 may be associated with order entry device 30 such that staff member 28 may enter an order placed by a customer into order entry device 30.
In some implementations, audio order receiving sub-system 24 may include one or more of a transceiver 44, a microphone 46, a speaker 48, a signal processor 53, and/or other components. Transceiver 44 may be configured to transmit encoded audio communication signals to transceiver 38 of base station 23 and receive encoded audio communication signals from transceiver 38. In some implementations, transceiver 44 may be configured to transmit and receive the encoded audio communication signals via one or more radio channels of a radio link. In some implementations, transceiver 44 may be configured to transmit and receive encoded audio communication signals substantially simultaneously. Transmitting and/or receiving encoded audio communication signals to and/or from transceiver 38 may facilitate communication between customer 32 (via audio order placement sub-system 22) and staff member 28.
In some implementations, similar to transceiver 38 described above, a communication protocol associated with transceiver 44 may be configured for narrow-band audio. The communication protocol may specify a number of bits per frame. For example, the communication protocol may specify 320 bits per frame.
Microphone 46 may be configured to receive sound generated by staff member 28 and to generate wideband order information signals that represent the received sound. The received sound may be in the wideband frequency range. In some implementations, microphone 46 may be associated with an analog to digital converter configured to digitize the received sound. The received sound may include, for example, sound communicating a confirmation of the food and/or beverage items from the menu board, a cost of the order, instructions to move a vehicle through drive-through lane 16 (shown in FIG. 1), and/or other information. In some implementations, microphone 46 may be held by audio order receiving sub-system 24.
Speaker 48 may be configured to receive wideband order information signals and to generate sound represented in the received wideband order information signals. In some implementations, speaker 48 may be associated with a digital to analog converter configured to generate analog audio for speaker 48. The sound may be generated such that the sound is audible to staff member 28. The sound represented in the received wideband order information signals may be the voice of customer 32 placing an order, for example. In some implementations, speaker 48 may be held by audio order receiving sub-system 24.
Signal processor 53 may be configured to encode and/or compress wideband order information signals received from microphone 46 into encoded audio communication signals for transmission by transceiver 44. Signal processor 53 may be configured to decode and/or decompress encoded audio communication signals received by transceiver 44 into wideband order information signals for speaker 48. For example, whether signal processor 53 is encoding or decoding may depend on whether communication is from a customer to a staff member or from a staff member to a customer. In some implementations, signal processor 53 may include one or more individual processing units. In some implementations, signal processor 53 may be configured to provide wideband noise suppression and/or acoustic echo cancellation (e.g., in the sound received by microphone 46). In some implementations, signal processor 43 of base station 23 may be configured to suppress noise received by microphone 46 of audio order receiving sub-system 24. In some implementations, signal processor 53 may perform digital audio data rate compression and/or decompression. In some implementations, signal processor 53 may perform digital audio data rate compression such that the encoded audio communication signals transmitted by transceiver 44 fit in the same radio data stream occupied by narrow band audio. In some implementations, an encoding and/or compression format may be associated with signal processor 53 such that the wideband order information signals may be compressed into frames having a number of bits per frame that is based on the communication protocol associated with transceiver 44 (e.g., 320 bits per frame).
In some implementations, signal processor 53 may provide up to about 8:1 data compression. In some implementations, signal processor 43 may provide data compression according to an algorithm such as BV32. In some implementations, signal processor 53 may provide less than 8:1 data compression. For example, signal processor 53 may provide less than 8:1 data compression when the transmitted signals occupy more than one time slot (e.g., for digital radios that use time division multiplexing). In some implementations, signal processor 53 may be integrated with transceiver 44 as a single component of audio order receiving sub-system 24.
The wideband order information signals and/or the encoded audio communication signals may represent sound having a frequency range in a wideband audio frequency range. The wideband order information signals and/or the encoded audio communication signals may represent sound having a wideband audio frequency range such that communication between customer 32 and staff member 28 may be accomplished in wideband audio. For example, accomplishing the communication between customer 32 and staff member 28 in wideband audio may facilitate enhancement of the voice clarity of staff member 28 heard by customer 32 and/or additional improvements relative to narrow band audio. In some implementations, the wideband order information signals and the encoded audio communication signals represent sound having a frequency range minimum and a frequency range maximum about 7000 Hz apart. In some implementations, the wideband order information signals and the encoded audio communication signals may represent sound having a frequency bandwidth of about 7000 Hz. In some implementations, the wideband order information signals and the encoded audio communication signals represent sound having a minimum frequency of between about 50 Hz and about 300 Hz, and/or a maximum frequency of up to about 8000 Hz. In some implementations, the wideband order information signals and the encoded audio communication signals may represent sound having a frequency range minimum and a frequency range maximum greater than about 4000 Hz apart. In some implementations, the wideband order information signals and the encoded audio communication signals may represent sound having a frequency bandwidth of greater than about 4000 Hz. As such, the components of system 10 may be specifically tailored for wideband audio communication. For example, the analog to digital and digital to analog converters may operate with 16 kHz sample rates and pass audio frequencies up to 8 kHz.
Returning to FIG. 1, order entry device 30 may be configured to receive entry and/or selection of orders from customers by staff member 28. In some implementations, staff member 28 may manually key the order information (e.g., food and/or beverage items from the menu board, quantities associated with the food and/or beverage items, pricing information), and/or other information into order entry device 30. In some implementations, staff member 28 may speak order information into order entry device 30 and/or input order information into order entry device 30 by other methods. In some implementations, order entry device 30 may manage payment for the orders. Managing payment may include processing credit card payments, receiving cash payments, and/or other management. Order entry device 30 may be configured to electronically send information related to the orders to kitchen display system 18. Examples of order entry device 30 may include cash registers, point of sale (POS) systems, and/or other devices.
FIG. 3 illustrates a method 400 of communication with a quick service restaurant intercom communication system. The operations of method 400 presented below are intended to be illustrative. In some implementations, method 400 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of method 400 are illustrated in FIG. 3 and described below is not intended to be limiting. In some implementations, two or more of the operations may occur substantially simultaneously.
In some implementations, method 400 may be implemented in one or more processing devices (e.g., a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information, a state machine, and/or other mechanisms for electronically processing information). The one or more processing devices may include one or more devices executing some or all of the operations of method 400 in response to instructions stored electronically on one or more electronic storage mediums. The one or more processing devices may include one or more devices configured through hardware, firmware, and/or software to be specifically designed for execution of one or more of the operations of method 400.
At an operation 402, an audio order placement sub-system may be positionally associated with respect to a menu board and/or a speaker post. The menu board and/or the speaker post may be associated with a quick service restaurant. In some implementations, the audio order placement sub-system may include a speaker and/or a microphone. In some implementations, the speaker and/or the microphone of the audio order placement sub-system may be mounted in the menu board. In some implementations, the speaker and/or the microphone of the audio order placement sub-system may be mounted in the speaker post. In some implementations, operation 402 may be performed by a menu board and/or a speaker post the same as or similar to menu board 20 and/or speaker post 21 (shown in FIG. 1 and described herein).
At an operation 404, sound may be received from a customer placing an order at or near the menu board. Wideband order information signals that represent the received sound may be generated. In some implementations, operation 404 may be performed by a microphone the same as or similar to microphone 34 (shown in FIG. 2 and described herein).
At an operation 406, the wideband order information signals that represent the sound received from the customer may be encoded into encoded audio communication signals for transmission. In some implementations, the wideband order information signals may be compressed before transmission. In some implementations, operation 406 may be performed by a signal processor of a base station the same as or similar to signal processor 43 (shown in FIG. 2 and described herein).
