Abstract
Techniques to detect echoes using audio fingerprinting are described. In one embodiment, an apparatus may comprise a streaming component operative to establish a audio connection between the first client device and a second client device; and receive a far-end audio stream at the first client device from the second client device via the audio connection; an audio capture component operative capture a near-end audio stream at the first client device; and an echo processing component operative to compare the near-end audio stream and the far-end audio stream to determine whether a far-end audio segment is present in the near-end audio stream; and use an echo-cancellation module at the first client device where the far-end audio segment is present in the near-end audio stream. Other embodiments are described and claimed.
