## Background
FIELD OF THE DISCLOSURE
This disclosure, in general, relates to announcement systems and methods of interacting with callers.
BACKGROUND
Increasingly, business transactions are handled via telephone including customer complaint and customer support handling. Businesses have established call centers to handle incoming call traffic and to interact with customers. However, these call centers, staffed by live people, tend to be expensive and difficult to staff.
Paying for call centers is an expensive proposition relative to automated methods, such as websites for Internet traffic. In addition, businesses have found that it is difficult to effectively train and maintain staffing at call centers. It is expensive to train personnel for call centers and at the same time it is difficult to retain trained call center agents. High turnover rates coupled with expensive training leads to a high cost for call centers.
To counteract this cost, businesses have turned to interactive voice response systems to provide automated answers to customer questions and to selectively route calls based on a call subject to a set of agents trained on a narrower set of subjects. Such systems have been found to reduce call center volume and to reduce training expenses associated with training call center agents.
However, customers complain of lengthy menus and difficulty in navigating such menus. Often, a customer calling a call center must wait through a lengthy menu or a series of menus in order to determine which option best suits his or her needs. After waiting through several menus and submenus, customers sometimes become frustrated, leading to poor customer satisfaction and potentially lost sales. As such, there is a need for an improved announcement system and method of interacting with callers.

In a further exemplary embodiment, the disclosure is directed to an announcement system having a computer readable memory. The computer readable memory includes an audio menu. The audio menu includes an opening statement voice prompt that requests a caller statement identifying a caller information. The audio menu also includes a plurality of menu option voice prompts. Each of the plurality of menu option voice prompts requests a caller statement or a numeric selection to indicate a caller request to receive information associated with the respective menu option voice prompt. The plurality of menu option voice prompts are ordered in a playback sequence based on a plurality of weighted factors.
In another exemplary embodiment, the disclosure is directed to an interactive call handling system including a call reception module, a factor engine, an audio clip sequencing engine, an announcement engine, a response system, and a call handling action system. The call reception module is configured to receive an incoming call. The factor engine is responsive to the call reception module and is configured to identify an ordered set of menu options based on a plurality of weighted factors. The audio clip sequencing engine is responsive to the factor engine and is configured to generate an ordered sequence of audio clips corresponding to the ordered set of menu options. The announcement engine is responsive to the audio clip sequencing engine and is responsive to the call reception module. The announcement engine is configured to play the ordered sequence of audio clips in the order of the ordered sequence in response to the incoming call. The response system is responsive to the call reception module and is configured to receive a caller selection from the incoming call. The caller selection is selected from one of the ordered set of menu options. The call handling action system is responsive to the response system and is configured to perform a call handling action on behalf of the incoming call in response to the caller selection.
An exemplary system is depicted in FIG. 1. An automated announcement unit 102 is connected to a Public Switched Telephone Network (PSTN) 104. A caller using a telephone 106 connected to the PSTN 104 may initiate a call and be directed to the automated announcement unit 102. The automated announcement unit 102 may play an ordered sequence of audio clips to produce an announcement and menu from which the caller may select options. The caller in one exemplary embodiment makes a voice statement or enters a Dual Tone Multi Frequency (DTMF) selection that is received by the response system 108. The response system 108 acts on the selection and initiates a call-handling action via the call handling action system 124. The call-handling action may, for example, lead to a subsequent menu, route the call to an agent, change a component of a caller service, or provide requested information.
The automated announcement unit 102 includes a call reception module 122, a factor engine 110, a sequencing engine 114, and a playing engine 120. The call reception module 122 is configured to receive a call. Data associated with the call may be routed to the factor engine 110. The factor engine 110 may access databases 112 and determine a set of menu options based on the information received in association with the call and based on information accessed via the databases 112. For example, the factor engine 110 may receive information associated with a call initiated by phone 106, such as a number dialed or a number associated with the phone 106. Using this information, the factor engine 110 may access databases 112 such as a billing history database, an order history database, an account information database, a product information database, and a service order database. Based on a set of factors, a set of menu options may be identified or selected, and, using a factor weighting table, these menu options may be ordered and provided to the sequencing engine 114. In one exemplary embodiment, each factor is used individually to determine or select a menu option and the selected menu options may be ordered based on weightings assigned to the factors associated with the menu options.
The sequencing engine 114 utilizes the ordered set of menu options to select audio clips from an audio clip database 116. The sequencing engine 114 orders the audio clips based on the ordered set of menu options to produce an ordered sequence of audio clips 118. The playing engine 120 accesses the ordered sequence of audio clips 118 to generate an announcement that is provided to the caller 106 via the call reception module 122 and the PSTN 104. In one exemplary embodiment, the caller at the phone 106 may provide a response, such as by speaking or by selecting a DTMF signal using a telephone keypad. The response system 108 interprets the selection, such as through voice recognition or DTMF recognition, and initiates a call-handling action in the call handling action system 124. In one exemplary embodiment, the response system 108 is coupled to the PSTN. Alternatively, the response system 108 may be coupled to the call reception module 122.
The automated announcement unit 102 may be implemented with a set of one or more processors or computational devices and software operable by the computational devices to implement the factor engine 110, the sequencing engine 114, the playing engine 120, and the call reception module 122. Data files such as menu options, a database of audio clips 116, and an ordered sequence of audio clips 118 may be stored in and accessed through computer-readable memory. Computer-readable memory may include RAM, ROM, hard drives, floppy drives, magnetic drives, optical drives, flash memory, and removable drives.
In one exemplary embodiment, the automated announcement unit 102 and the response system 108 may be a component integrated into an IVR system. In another exemplary embodiment, the automated announcement unit 102 may be incorporated into a node of an advanced intelligent network (AIN).
FIG. 2 depicts an exemplary method 200 for interacting with a call. The method 200 includes receiving a call at an automated announcement unit, as shown at step 202. An announcement having a plurality of audio clips is identified, as shown at step 204. For example, the announcement may be an opening announcement and a menu, a submenu, or an emergency announcement. An ordered set of menu options may be determined based on a plurality of weighted factors, as shown at step 206. The automated announcement unit determines an ordered sequence of audio clips corresponding to the ordered set of menu options, as shown at step 208. The announcement unit generates an announcement with respect to the call at the automated announcement unit by playing the ordered sequence of audio clips, as shown at step 210. The system may receive a user selection after generating the announcement, as shown at step 212. Alternately, the user may provide a response concurrently with the playing of the announcement, such as when the user hears a desired menu option. In one example, the user may provide a voice response or may provide a DTMF selection to a response unit. In response to the user selection, the system performs a call-handling action, as shown at step 214. The call-handling action may, for example, include routing of the call to an agent, accessing a submenu, or providing requested information.
In a particular exemplary embodiment, the ordered set of menu options is determined based on a plurality of factors. Each factor is associated with an option based on rules and logic associated with the factor. Using a factor weighting table, the options are ordered. Exemplary factors include option selection frequency, geographic region, caller characteristics, different frequency time intervals, marketing priorities, and exception conditions.
For example, frequency with which a menu item is selected by callers may be used to adapt menus dynamically or to select specific menu options. Regional data, such as the destination of a call or the origin of a call, may be used in determining or selecting a menu option. For example, regional data may determine what services and products are available to a customer. In addition, caller characteristics may be used in the selection of a menu option. For example, an automatic number identification (ANI) system may identify a caller, allowing a system to look up information in a customer database. The information may, for example, include billing history, personal history, features associated with the number, past orders, and caller market segment. For example, if an individual recently purchased CallNotes®, then a menu item associated with the caller characteristic might include CallNotes® as an option, such as help information describing use of CallNotes®.
Menu option frequencies may be calculated over different time periods. Differing time intervals over which frequencies are determined may be used as factors in determining a set of menu options. For example, a recent marketing campaign may have increased the frequency of calls associated with a particular product over a short-time period (i.e. 6 months), while longer term frequency calculations indicate that other options are more likely to be requested. In this manner, both the menu option having an associated recent high call frequency and the menu options having longer-term sustained interest may be included in the set of menu options.
Further, marketing campaigns and priorities may be used in the selection of a menu option. Marketing campaigns may emphasize a special promotion for a product and thereby generate calls relating to that product. Relying on historical call frequency alone would delay the emphasis of a menu option while pre-specifying the menu option for the promoted product would present a selection option targeted to early responders to the marketing efforts. In addition, exception conditions, such as pre-emptive events, (e.g. outages and natural events) may be used in determining menu options. For example an announcement may be preempted with a statement acknowledging the outage of a DSL network, assuring customers that the problem has been recognized and is being rectified. In this manner, each factor may be used to select a menu option. The selected menu options are ordered based on weightings associated with each factor.
FIG. 3 depicts an exemplary weighting table. The factors, such as factors 1 through 5, may be used in determining a set of menu options, as depicted in the score column. In this example, factor 1 results in the selection of option clip 1, factor 2 results in the selection of option clip 2, factor 3 results in the selection of option clip 3, factor 4 results in the selection of option clip 2, and factor 5 results in the pre-emptive clip selection. Each factor has an associated weighting, as shown in the weight column. In this example, the weights may be used in ordering the selected menu options. For example, the total weighting associated with option clip 2 equals 60%. Logic associated with both factor 2 and factor 4 resulted in the selection of option clip 2 and the sum of the weights associated with factors 2 and 4 result in a weighting of 60% associated with options clip 2. Option clip 3 receives a weighting of 30% and option clip 1 receives a weighting of 10%. In this exemplary embodiment, the pre-emptive clip is provided with a zero weighting. However, in the event that a pre-emptive event occurs, the weighting of the pre-emptive clip may be switched to 100%. As a result of the exemplary weightings, the order of the example menu options would be option clip 2, followed by option clip 3 and then option clip 1.
FIG. 4 depicts an exemplary ordering or sequencing of a set of audio clips. This ordered set of audio clips may be stored in memory and played to produce an announcement or message 400. In this exemplary embodiment, a set of general clips 1 and 2 (402 and 404) are ordered prior to a set of menu option clips (406, 408, and 410). In this particular embodiment, the general clips 402 and 404 may be a fixed set of audio clips and the option clips may be an adaptive set of audio clips that are rearranged based on the weighted factors. For example, the system may play a message such as:
“Welcome to SBC®'s phone service guide. Please tell me which phone service you would like information about. I have information about CallNotes®, call forwarding, and call blocking.”
In this example, general clip 1 (402) may include “Welcome to SBC®'s phone service guide. Please tell me which phone service you would like information about.” General clip 2 (404) may include “I have information about”. The option clips (406, 408 and 410) may include an ordered sequencing of options. For example, option clip 1 (406) may include “CallNotes®”. Option clip 2 (408) may include “call forwarding” and option clip 3 (410) may include “call blocking”. While playing the announcement, the user may speak to make a voice selection or depress a touchtone number on a telephone keypad to provide a caller selection that is interpreted by a response system resulting in a call-handling action.
When another call is received the audio menu options may be ordered, as depicted in FIG. 5. The announcement of FIG. 5 includes the general clips 502 and 504, followed by a different ordering of option clips, such as option clip 2 (506), followed by option clip 1 (508) and option clip 3 (510).
While the examples depicted in FIG. 4 and FIG. 5 include a fixed set of general clips, the set of general clips may be adapted based on a set of factors as well. For example, a general clip 1 (602) may be followed by a general clip 3 (604) instead of a general clip 2. In addition, the option clips may be ordered in association with the factors to provide an order of option clips 606, 608 and 610. For example, such ordering may be used to accommodate regional variations in language preferences.
In another exemplary embodiment, the pre-emptive clip 702 may be provided on its own, prior to general clips or as a substitute for the option clips. FIG. 7 depicts an exemplary message 700 that includes a pre-emptive clip 702 prior to general clip 704 and the ordered set of option clips 706, 708, and 710. For example, if a service outage of a specific product were to occur, a call center might receive an increased volume of calls associated with that service outage. A pre-emptive clip may be utilized to provide the caller with information about the service outage, to provide an option prior to the general menu for the caller to select, or assure or assuage the caller that the outage is being remedied.
The messages depicted in FIGS. 4 thought 7 depict data that may be used by an interactive voice response system in playing announcements to illicit menu selections from a caller. In an alternate embodiment, a system may be set up to encourage DTMF selection. In this exemplary embodiment, clips that are associated with the ordering of the options such as clips that state Number One, Number Two and Number Three, etc., may be provided. FIG. 8 depicts an exemplary ordering. For example, the announcement 800 may include general clips #1 and #2 (802 and 804) followed by a pairing of number clips and option clips. In this example, number clip #1 may announce “#1” or “option 1” followed by option clip #1. Similarly, number clip #2 may announce “#2” followed by the next option clip in the ordered sequence, such as option clip #3. In a further example, number clip #3 is followed by option clip #2. When the option clips are reordered in accordance with data associated with a subsequent call, the number clips remain in their relative sequence and the option clips associated with the number clips are reordered. In general, the number clips are sequenced into the announcement prior to an associated option clip from the ordered sequence of option clips. For example, a clip intonating “one” may be sequenced in advance of the first ordered or selected option clip followed by an audio clip intonating “two”, which is sequenced in advance of a second ordered or selected option clip. In this manner, the system may be set up to allow for either one or both of voice response or DTMF response systems.
The above-disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments, which fall within the true scope of the present invention. Thus, to the maximum extent allowed by law, the scope of the present invention is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited by the foregoing detailed description.
