Abstract:
1. A method for evaluation of the quality of a bi-directional transmission channel while the bi-directional transmission channel is being used to transmit an electronic speech signal that is derived from speech that was spoken by a human speaker and captured at a near end of the bi-directional transmission channel, where the speech signal is transmitted over the bi-directional transmission channel and used to reproduce the speech at a far end of the bi-directional transmission channel, the method comprising: determining near-end characteristics of the speech at the near end of the bi-directional transmission channel; determining, at the far end of the bi-directional transmission channel and from the transmitted speech signal, far-end characteristics of the speech; comparing the near end and far end speech characteristics and developing comparison results; and causing notification of the speaker if the comparison results do not meet a predetermined quality metric: wherein at least one of the far end speech characteristics and the comparison results are transmitted over the bi-directional transmission channel to the near end of the bi-directional transmission channel.
