Audio Transmission Channel Quality Assessment

摘要

A device, system and method for audio transmission quality assessment that occurs during the transmission. A transmission channel such as the internet is used to transmit speech that is spoken by a human speaker, captured at a first end, and transmitted over the transmission channel for reproduction at a second end. The processors at each end of the transmission channel are configured to determine one or more characteristics of the speech such as phonemes. The phonemes are transmitted over a backchannel of the transmission channel to a processor that compares the speech characteristics that were determined at both ends of the call. The participants are notified of a transmission problem that has had an effect on the intelligibility of the speech that was reproduced at the far end if the comparison does not meet a predetermined quality metric.

1. A method for evaluation of the quality of a transmission channel while the transmission channel is being used to transmit speech that was spoken by a human speaker, captured at a near end, and transmitted over the transmission channel for reproduction at a far end, the method comprising:
determining characteristics of the speech at both the near end and the far end; comparing the speech characteristics determined at the near end and those determined at the far end; and causing notification of the speaker if the comparison does not meet a predetermined quality metric.
