Abstract

<P>PROBLEM TO BE SOLVED: To provide a voice quality converting device capable of adequate voice quality conversion to a natural speech without letting a speaker perform troublesome work. <P>SOLUTION: A formant movement section 26 assumes a coordinate system on which coordinates are determined by the combination of a plurality of formant frequencies and uses a feature model (voice quality conversion rule) found on the basis of distributions of coordinates represented by a plurality of different voices of a conversion source speaker and a target speaker to move formant frequencies F1 and F2 that a formant frequency detection section 25 detects while targeting frequency components of respective channels input from a phase compensation section 24. Consequently, the voice of the conversion source speaker is converted into the voice of the target speaker through voice quality conversion. <P>COPYRIGHT: (C)2007,JPO&amp;INPIT
【課題】 話者に面倒な作業を行わせることなく、自然な音声に適切に声質変換できる声質変換装置を提供する。 【解決手段】 フォルマント移動部26は、複数のフォルマント周波数の組み合わせで座標が定まる座標系を想定し、変換元話者、目標話者の異なる複数の音声によってそれぞれ表される座標の分布を基に求めた特徴モデル(声質変換規則)を用いて、位相補償部24から入力した各チャンネルの周波数成分を対象に、フォルマント周波数検出部25が検出したフォルマント周波数F1、F2を移動させる。それにより、変換元話者の音声を目標話者の音声に声質変換する。 【選択図】 図2
