Claim:
1. A method performed by a teleconference computing device for suppressing transient noise in an audio signal, the method comprising: estimating a voice probability for a segment of the audio signal containing transient noise, the estimated voice probability being a probability that the segment contains voice data; responsive to determining that the estimated voice probability for the segment is greater than a threshold probability, suppressing the transient noise contained in the segment of the audio signal while reducing distortion of the voice data, including: responsive to determining that the estimated voice probability for the segment is less than the threshold probability, suppressing the transient noise contained in the segment of the audio signal while not reducing distortion of the voice data, including: wherein the transient noise is at least one of feedback noise, fan noise, and button-clicking noise due to mechanical connection between an audio capture device and a keyboard or trackpad of the teleconferencing computing device.
