摘要: An echo canceller can be arranged to receive an input signal and a reference signal. The subtract linear component of the from A noise suppressor suppress non-linear effects in correspondence with large number selectable parameters. Such suppression provided on frequency-by-frequency basis, unique set tunable parameters selected for each frequency. degree by correspond estimate residual remaining after one or more components have been subtracted signal, estimated double-talk probability, signal-to-noise ratio near-end speech respective recognizer processed suppressor.
