SPEECH PROCESSING DEVICE AND SPEECH PROCESSING METHOD

The speech processing method determines the probability of speech of a speaker on the proximal side included in a speech signal picked up by a first microphone, determines the gain of the speech signal on the basis of the determined probability, processes the speech signal on the basis of the determined gain of the speech signal, and sends the processed sound signal to a far-end side. 语音处理方法求出由第1传声器拾音到的声音信号所包含的近端侧的说话者的语音的概率，基于求出的所述概率而决定所述声音信号的增益，基于决定出的所述声音信号的增益对所述声音信号进行处理，将处理后的所述声音信号发送至远端侧。
