发明名称 Method and apparatus employing a vocoder for speech processing
摘要 A vocoder (125) is initialized, prior to processing an initial batch of audio data, from parameters extracted from the first frame of audio data (308, 310, 320, 330, 332). In the instant embodiment, parameters affecting voice encoding, which are based on estimates of direct current bias, are used to program a high pass filter (253) incorporated in the vocoder (125).
