    • 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 back channel 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.
    • 用于在传输期间发生的用于音频传输质量评估的设备,系统和方法。 诸如因特网之类的传输信道被用于发送在第一端捕获的由人类讲话者说出的语音,并且在第二端通过传输信道发送再现的语音。 传输信道的每一端的处理器被配置为确定语音的一个或多个特征,例如音素。 音素通过传输信道的反向信道传输到比较在呼叫两端确定的语音特征的处理器。 通知参与者如果比较不符合预定质量度量,那么对远端再现的语音的可懂度具有影响的传输问题。
