## Title
Voicemail system with quality assurance

## Abstract

In one embodiment, a method for ensuring quality of a media message is provided. The method includes receiving information for a media message. At least a portion of the media is analyzed to determine a media quality for the media message. The method then determines if the media quality is acceptable. If the media quality is not acceptable, then an alert may be sent regarding the media quality of the media message. For example, a caller may be prompted to re-record a media message.

## Background
TECHNICAL FIELD
Particular embodiments generally relate to telecommunications.
BACKGROUND
As callers leave media messages using a media system, most systems monitor the power of the recorded message. If the power of the message is below a preconfigured threshold, the media system alerts the caller that the recipient may have a hard time understanding the message. For example, the media system may play a suitable prompt, such as “We did not receive your message. Please press 1 and re-record the message at the sound of the beep.”
Power monitoring is used because old systems wanted to save disk space and because this simple measurement requires little CPU processing power. Measuring the power may be acceptable for detecting silence; however, additional factors may affect the quality of a media message other than power. Thus, even if power is monitored, a recipient may still not be able to understand a media message.

DESCRIPTION OF EXAMPLE EMBODIMENTS
Overview
In one embodiment, a method for ensuring voice quality of a media message is provided. The method includes receiving information for a media message. At least a portion of the information is analyzed to determine voice quality for the media message. The method then determines if the voice quality is acceptable. If the voice quality is not acceptable, then an alert may be sent regarding the voice quality of the media message. For example, a caller may be prompted to re-record a media message.
Example Embodiments
FIG. 1 depicts an example system 100 for providing quality assurance for a voicemail system 102. A caller end point 104 may contact voicemail system 102. A caller may use caller end point 104 to record/leave a message for a recipient. A recipient may use a recipient device 106 to listen to a media message left using voicemail system 102.
Voicemail system 102 may be any system that allows media messages to be recorded. For example, voicemail system 102 may include a media is connected to caller end point 104. A caller may then use caller end point 104 to record and store a media message with voicemail system 102. Although a “voicemail system” is discussed, it will be understood that any system that can store media for quality analysis may be used, such as a unified messaging system, instant messaging system, etc. The media message may include any data in any form. For example, the media message may be a voice message, video message, any multimedia message, etc.
Caller end point 104 may be any device/application that can leave/record a media message. For example, caller end point 104 may include a cellular phone, PSTN phone, instant messaging client with voice enabled, laptop computer application, VoIP telephone, video phone, etc.
In one embodiment, caller end point 104 may attempt to contact a recipient. If the recipient does not answer the call, then voicemail system 102 picks up the call (e.g., the call is redirected to a voicemail server).
Voicemail system 102 includes an interactive voice response (IVR) system that may allow a caller to leave a media message for the recipient. A menu system is provided that allows the caller to record/leave a media message.
Particular embodiments analyze information for a media message being left to determine the media message's media quality. Media quality is measured in real-time as a caller leaves a message that is audible (i.e., has enough power) but the media quality may be poor. The media quality may be any analysis on the quality of the media message. For example, the recording quality of the media message is analyzed. This may analyze the voice quality of the media message. Further, the media quality may analyze other aspects of the media quality, such as whether the video can be understood (either voice or video quality). If a message is considered to have poor media quality, the message may be hard to understand for various reasons. For example, when a caller is using a cellular phone, there may be a poor connection when leaving the message. Thus, the caller's voice may be muffled, garbled, robotic sounding, etc. When a recipient listens to a media message with poor media quality, the recipient may not be able to understand or comprehend what the caller has sent e.g., what the caller has spoken, sent in a video, etc.). This is different than when the power is low in that either nothing was said or the recipient cannot hear audio in the media message that was left.
When the voicemail system 102 determines that the media quality is unacceptable for a media message, then it may send an alert indicating that the media quality is not acceptable. For example, voicemail system 102 may send a prompt to a caller indicating that the media quality is not acceptable and suggest that the caller may want to re-record a new message. Accordingly, the caller may record another message in place of the already left message.
FIG. 2 shows an example of a method 200 for determining media quality. Step 202 receives media for a media message. The media received for the media message may be media from the actual media message being left by the caller. For example, packets of media may be received with audio information for the media message. Also, the information may be data other than the actual media message spoken by the caller. For example, the information may be numbers of packets lost, transmission channel errors, a noise reading, transcoding information, delay in packets being sent, short-term and long-term warping of a speech signal, a frequency signature of the media, a speech recognition of the audio of the media message, etc.
Step 204 then analyzes the information media quality. Various methods may be used to analyze the media quality. For example, voice quality algorithms that measure the quality of voice may be used. In one embodiment, algorithms described in the standards ITU P.VTQ or P.563 for analyzing voice quality (VQ) may be used. An example of the P.563 standard is described in ITU P.563 recommendation “Single-ended Method for Objective Speech Quality Assessment in Narrow-band Telephony applications”, which is incorporated by reference in their entirety for all purposes.
In one embodiment, the algorithms may accurately detect the following: impairments of packet loss and packet loss concealment with code-excited linear prediction (CELP) codecs, transmission channel errors, environmental noise at the sending side, transcodings, effect of varying delay on listening quality in absolute category rating (ACR) tests, short-term time warping of a speech signal, long-term time warping of a speech signal, etc. Other impairments may also be detected. For example, a robotic voice signature that may be caused by packet loss concealment may also be detected.
Other analysis may also be used. For example, natural language recognition (NLR) may be used to parse the recorded media message. If voicemail system 102 has difficulty deciphering parts of the message, then it may be determined that the media quality is poor.
In another embodiment, voicemail system 102 may identify segments in the media message that contain poor media quality by estimating poor cellular connectivity. For example, certain signature or frequencies of a spectrum filter suggest that voice may be distorted.
Further, packet loss concealment may be used. In VoIP, packets may be lost along the way to voicemail system 102. If enough packets are lost, then it may be assumed that there is poor media quality.
In another specific embodiment, step 204 may utilize video quality analyzing algorithms. Various methods may be used to analyze the video quality. For example, video quality algorithms that measure the quality of video may be used. In one embodiment, algorithms described in the standards ITU STUDY GROUP 9 of the Video Quality Experts Group (VQEG) for analyzing video quality (VQ) may be used. The “final Report from the Video Quality Experts Group on the Validation of Objective Models of Video Quality Assessment” is incorporated by reference in their entirety for all purposes. This report describes the results of the evaluation process of objective video quality models as submitted to the Video Quality Experts Group (VQEG). The report describes models to be used in the calculation of objective scores for comparison with subjective evaluation over a broad range of video systems and source sequences.
Step 206 then determines if the media quality is acceptable. For example, the analysis in step 204 may provide a measurement data point. This data point may be compared to a threshold to determine whether the media quality is acceptable or not. For example, if a number of packets are lost above a certain threshold, it may be determined that the media quality is poor. Also, any of the impairments discussed above may be compared to a threshold to determine if media quality is poor or not. Further, in speech recognition, if a large number of words are not recognized above a threshold, then it may be determined that the recipient may have trouble understanding the media message and thus it may be considered of poor media quality.
In one embodiment, segments of a media message may be analyzed for media quality. Instead of analyzing the entire message as a whole, short segments may be analyzed for media quality rather than analyzing the average overall quality of a media message. For example, voicemail system 102 may treat the overall media message as a sequence of a number of segments and may measure the media quality of each segment. If voicemail system 102 determines that any of the segments include poor media quality, then these segments may be flagged as being of poor media quality. However, segments that are of acceptable media quality may not be flagged.
If the media message is considered acceptable, step 208 accepts the media message. For example, the whole media message or none of the segments of the media message may have been considered to be poor.
If the media message is not considered acceptable, then step 210 performs an action in response to the poor quality determination, such as sending an alert indicating that it was determined that the media message was not considered acceptable. If the entire message is considered poor (or the determination was averaged for the entire media message), then the caller may be asked to re-record the media message again. Also, different way of treating segments of poor quality may be used. For example, the caller may be asked to re-record the segments that were considered of a poor quality. Also, the caller may be able to re-record the entire message from the beginning even though only a few segments were considered unacceptable.
Another option may be that the caller can listen to the segments or the entire media message and determine if the media quality is acceptable. If the media quality is acceptable, the caller may commit it to voicemail system 102. If the media quality is not acceptable, then the caller may re-record a new message.
A selective analysis of media quality may also be performed. For example, voicemail system 102 may detect when a media message is being left from a medium that may result in poor media quality. In one example, voicemail system 102 may detect that a caller is leaving a message from a mobile phone. This may be performed by using the caller ID of incoming calls to determine if the call originates from a mobile phone. Thus, users in media in which it is not likely that poor media quality results may not have to deal with false positives indicating that media quality is poor. For example, callers using PSTN telephones may not need to have their media quality analyzed. Also, carriers may provide analysis on certain calls, such as a phone company may provide quality assurance on calls between two end points it owns. This may provide better voice quality for customers using the same phone company. However, if the call is from an end point from another carrier, the quality assurance may not be provided.
FIG. 3 depicts a more detailed example of voicemail system 102. As shown, a media quality analyzer 302 and a media quality alerter 304 are provided. Media quality analyzer 302 is configured to receive information for the media message. Media quality analyzer 302 then analyzes the information for media quality. It can then determine if the media quality is acceptable or not.
If the media quality is not acceptable, then media quality alerter 304 is configured to alert a caller of the poor media quality. Media quality alerter 304 may then give the caller options of checking the media for media quality, re-recording the message, etc.
Accordingly, particular embodiments provide many advantages. When a caller leaves a media message and hangs up, the caller cannot go back and change the message that has been left in the recipient's voicemail box. Thus, it is important to ensure that the media quality of the media message being left is acceptable while the caller is connected to voicemail system 102. Thus, real time media quality assurance is provided using particular embodiments. If it is detected that media quality is poor, then the caller may be alerted before disconnecting from voicemail system 102. This may allow a caller to re-record a media message if the media quality is poor. This ensures that media messages left are of good voice quality.
Checking the quality of a recorded message is useful as new media are being used to make calls, such as VoIP, cellular, video phones, land mobile radios (LMR), etc. These new media may not be as reliable as other technologies. Further, the intercommunication between end points in different mediums may not always produce the highest quality voice calls. Thus, ensuring that voice quality is acceptable may be more important than detecting silence (e.g. the power).
Also, particular embodiments may be useful when quality assurance is imperative in media recordings. For example, some fields require recording and storing of all media messages for regulatory or legal reasons. Also, for legal reasons, some companies may need to keep media messages. If the stored messages have poor voice quality, their usefulness may be degraded. Thus, techniques to ensure good recording quality are desirable.
