Abstract:
1. A system, comprising: estimation logic configured to calculate characteristics associated with at least a near-end speech signal to be transmitted by an audio device, the calculated characteristics including an estimated level of near-end background noise that is associated with the near-end speech signal, the estimated level including a plurality of estimations of the near-end background noise corresponding to a plurality of respective sub-band components of the near-end speech signal; a processing module configured to receive the calculated characteristics and to modify a far-end speech signal, which is received for playback by the audio device, based on at least the calculated characteristics to increase the intelligibility thereof by boosting the far-end speech signal over the near-end background noise by performing spectral shaping on the far-end speech signal based on one or more of the estimations corresponding to one or more of the sub-band components; and an acoustic echo canceller configured to receive the calculated characteristics and to suppress acoustic echo present in the near-end speech signal based on at least the calculated characteristics.
