Description

本発明は一般に音響的（acoustically、以下、聴覚的という。）に感知された信号の処理に関する。 The present invention relates generally to the processing of acoustically sensed signals.

人間の頭脳内の処理により生じる方法で音声信号の精度を高める手法も存在する。それらは一般に計算機による聴覚情景解析（ＣＡＳＡ）と称される。人間は異なる同時の音声を区別して１つの音源に集中することができることが分かっている。それを支える仕組みは様々な時間周波数領域を１つの音源に結び付け或いはグループ分け（group、以下、グループピングという）するように働くことのできる手がかりに基づいて信号を分離できることである。そのような手がかりは例えば、基本周波数、空間内の位置、或いは共通オン及びオフのセットである。 There is also a technique for improving the accuracy of an audio signal by a method generated by processing in the human brain. They are generally referred to as computerized auditory scene analysis (CASA). It has been found that humans can distinguish different simultaneous sounds and concentrate on one sound source. The mechanism that supports this is that signals can be separated based on clues that can work to link or group various time-frequency domains into a single sound source. Such cues are, for example, fundamental frequencies, positions in space, or common on and off sets.
