Abstract:
1. A method of performing voice-switching for periods of doubletalk between a near-end teleconference device and a far-end teleconference device, the method comprising: receiving far-end voice data from the far-end teleconference device; receiving near-end voice data at the near-end teleconference device; identifying frequency subbands of the near-end voice data that have substantial energy; and before playing the far-end voice data on one or more loudspeakers of the near-end teleconference device, passing the far-end voice data to an audio unit, the audio unit selectively attenuating or eliminating from the far-end voice data frequency subbands of the far-end voice data that correspond to the identified frequency subbands of the near-end voice data, and wherein the audio unit does not attenuate or eliminate subbands of the far-end voice data that do not correspond to the identified frequency subbands of the near-end voice data.
