摘要： A power spectrum estimation unit (200) obtains an estimated sound power spectrum Ps(ω), based on a power spectrum P1(ω) and on a first calculated value obtained by at least multiplying a power spectrum P2(ω) by a weight coefficient A2(ω). A coefficient update unit (300) updates the weight coefficient A2(ω) and a weight coefficient A1(ω) so that a second calculated value approximates to the power spectrum P1(ω). The second calculated value is obtained by adding at least two values obtained by multiplying the power spectrum P2(ω) and the estimated target sound power spectrum Ps(ω) by the weight coefficient A2(ω) and the weight coefficient A1(ω), respectively.

摘要： A low-cost speech recognition apparatus for AV equipment capable of speech recognition with high accuracy while 2-channel sound is being produced from loudspeakers is achieved. A monaural conversion part converts 2-channel signals to be inputted to the loudspeakers into a monaural signal. A single echo canceller is provided with an output from a microphone and an output from the monaural conversion part (monaural signal). The echo canceller estimates an echo of multichannel sound based on the monaural signal, and then eliminates the echo sound from the microphone output. Thus, with only a single echo canceller, speech recognition can be carried out while 2-channel sound is being produced from the loudspeakers. Moreover, unlike the case where two echo cancellers are provided, the present invention can prevent the occurrence of mutual interference between the echo cancellers that leads to deterioration in speech recognition performance.
摘要翻译：实现了一种用于AV设备的低成本语音识别装置，其能够在从扬声器产生2声道声音的同时以高精度进行语音识别。单声道转换部分将要输入到扬声器的2声道信号转换为单声道信号。单个回声消除器具有来自麦克风的输出和来自单声道转换部分（单声道信号）的输出。回声消除器基于单声道信号估计多声道声音的回波，然后消除来自麦克风输出的回声。因此，仅使用单个回声消除器，可以在从扬声器产生2声道声音的同时进行语音识别。此外，与提供两个回波消除器的情况不同，本发明可以防止导致语音识别性能劣化的回波消除器之间的相互干扰的发生。

摘要： An array microphone is a directional microphone having an improved directional characteric in which both the sensitivity and the sound pressure frequency response are uniform within the recording area and more particularly, the quality and level of sound remain unchanged. The array microphone includes a microphone array including a plurality of microphone units, and a two-dimensional filter for filtering an output of the microphone array in the dimensions of both time and space. When the two-dimensional filter is a digital filter and varied in its two-dimensional filter coefficient and sampling frequency, the array microphone serves as a variable directional microphone whose directional characteristic can be varied with the sound quality and level remaining unchanged throughout the recording area.

摘要： A sound processing apparatus which can improve precision of analyzes on ambient sounds, carries out analysis on the ambient sounds based upon collected sound signals acquired by two sound collectors. The sound processing apparatus is provided with a level signal converter that converts the collected sound signal into a level signal, which indicates an absolute value of the collected sound signal from which phase information is removed. A level signal synthesizer generates a synthesized level signal in which the level signals acquired from the collected sound signals of the two sound collectors are synthesized, and a detector/identifier carries out analysis on the ambient sounds, based upon the synthesized level signal.
