Devices, systems and methods are disclosed which relate to a plurality of multimedia devices operating on a common time base having the ability to synchronize playback of a multimedia sample. A user initiates a synchronized playback by sending a request to one or more multimedia devices across a network. The user selects a multimedia sample and a start time. When the request is received by other multimedia devices on the network it can be accepted or denied. If the recipient accepts, the multimedia sample can be downloaded or cached before or streamed at the time of play. Many can enjoy listening to the same multimedia sample even using headphones. This enables a group to enjoy synchronized movement without requiring a sound system other than headphones.

Disclosed herein are systems, methods, and computer-readable storage media for processing a message received from a user to determine whether an estimate of intelligibility is below an intelligibility threshold. The method includes recognizing a portion of a user's message that contains the one or more expected utterances from a critical information list, calculating an estimate of intelligibility for the recognized portion of the user's message that contains the one or more expected utterances, and prompting the user to repeat at least the recognized portion of the user's message if the calculated estimate of intelligibility for the recognized portion of the user's message is below an intelligibility threshold. In one aspect, the method further includes prompting the user to repeat at least a portion of the message if any of a measured speech level and a measured signal-to-noise ratio of the user's message are determined to be below their respective thresholds.

System and method for automatic verification of the understandability of speech

The present invention relates to a system and method for automatically verifying that a message received from a user is intelligible. In an exemplary embodiment, a message is received from the user. A speech level of the user's message may be measured and compared to a pre-determined speech level threshold to determine whether the measured speech level is below the pre-determined speech level threshold. A signal-to-noise ratio of the user's message may be measured and compared to a pre-determined signal-to-noise ratio threshold to determine whether the measured signal-to-noise ratio of the message is below the pre-determined signal-to-noise ratio threshold. An estimate of intelligibility for the user's message may be calculated and compared to an intelligibility threshold to determine whether the calculated estimate of intelligibility is below the intelligibility threshold. If any of the measured speech level, measured signal-to-noise ratio and calculated estimate of intelligibility of the user's message are determined to be below their respective thresholds, the user may be prompted to repeat at least a portion of the message.

A voice processing system comprises a processing device that processes and receives a stream of voice input as a user is speaking. A software program executes program steps for determining a predetermined pattern of speech and silence during processing of stream of voice input so as to play or present the predetermined backchannel response to the user. A method provides an audible backchannel response between the voice processing system and the user, while the user is speaking, in particular, recording a message. The method includes monitoring the message to determine a predetermined pattern of speech and silence based on timing between the speech and silence periods. Then, the method produces the audible backchannel response based on the predetermined pattern. An audible user interface includes a speech processor that processes or classifies an audio message in the telecommunication device as speech and silence frame while a calling party is speaking, in particular, recording the audio message to a called party. A control circuitry cooperates with the speech processor and responds to a predetermined pattern of the speech and silence segments so as to play the preset backchannel response in audible form to the calling party.

Systems for testing and comparing audio teleconference quality for one or more voice teleconference systems can include at least two recording devices, a connection to each participant, and a test of the recording qualities. Each participant is connected in an audio teleconference through a transmission system using an audio teleconference bridge. Each participant is recorded as an individual track, wherein the individual tracks are synchronized in order to create a multi-track standard source recording. A second recording device recording the audio teleconference through the audio teleconference bridge and transmission system and forms a second recording. The second recording is tested to evaluate the quality of the audio teleconference.
