Near-end indication that the end of speech is received by the far end in an audio or video conference
First Claim
1. A client device for use in an audio or video conference system, comprising:
- an offset detecting unit configured to detect an offset of speech input to the client device;
a configuring unit configured to, for each of at least one far end, determine a first voice latency from the client device to the far end;
an estimator configured to, for each of the at least one far end, estimate a time when a user at the far end perceives the offset, based on the first voice latency; and
an output unit configured to, for each of the at least one far end, output a first perceivable signal indicating that a user at the far end perceives the offset based on the time estimated for the far end;
whereinthe output unit is configured to output one of subtle reverb and noticeable noise field not audible to other parties during a period after the offset detecting unit detects the offset and before the output unit outputs the first perceivable signal.

Abstract
Embodiments of client device and method for audio or video conferencing are described. An embodiment includes an offset detecting unit, a configuring unit, an estimator and an output unit. The offset detecting unit detects an offset of speech input to the client device. The configuring unit determines a voice latency from the client device to every far end. The estimator estimates a time when a user at the far end perceives the offset based on the voice latency. The output unit outputs a perceivable signal indicating that a user at the far end perceives the offset based on the time estimated for the far end. The perceivable signal is helpful to avoid collision between parties.

11. A client device for use in an audio or video conference system, comprising:
-
a receiving unit configured to receive data frames; a voice activity detector configured to detect voice activity in the data frames directly output from the receiving unit; and an output unit configured to output a perceivable signal indicating that there is incoming speech from a far end, wherein the voice activity detector is further configured to detect voice activity from local audio input, and the output unit is further configured to output another perceivable signal indicating that there is a collision if both voice activities are detected from the data frames and the local audio input at the same time.

12. A method of audio or video conferencing for use in a client device, comprising:
-
a configuring step of, for each of at least one far end, determining a first voice latency from the client device to the far end; a detecting step of detecting an offset of speech input to the client device; an estimating step of, for each of the at least one far end, estimating a time when a user at the far end perceives the offset, based on the first voice latency; an outputting step of, for each of the at least one far end, outputting a first perceivable signal indicating that a user at the far end perceives the offset based on the time estimated for the far end; and outputting one of subtle reverb and noticeable noise field not audible to other parties during a period after detecting the offset and before outputting the first perceivable signal. - View Dependent Claims (13, 14, 15, 16, 17, 18)
