语音质量转换装置和语音质量转换方法，用于使用对应于输入语音的目标声道信息和接收到的声道信息来转换输入语音的语音质量

Voice quality conversion device and voice quality conversion method for converting voice quality of an input speech using target vocal tract information and received vocal tract information corresponding to the input speech
Abstract:
A voice quality conversion device including: a target vowel vocal tract information hold unit holding target vowel vocal tract information of each vowel indicating target voice quality; a vowel conversion unit (i) receiving vocal tract information with phoneme boundary information of the speech including information of phonemes and phoneme durations, (ii) approximating a temporal change of vocal tract information of a vowel in the vocal tract information with phoneme boundary information applying a first function, (iii) approximating a temporal change of vocal tract information of the same vowel held in the target vowel vocal tract information hold unit applying a second function, (iv) calculating a third function by combining the first function with the second function, and (v) converting the vocal tract information of the vowel applying the third function; and a synthesis unit synthesizing a speech using the converted information.
Abstract(Chinese):

一种语音质量转换装置，包括：目标元音声道信息保持单元，保持表示目标语音质量的每个元音的目标元音声道信息; 元音转换单元（i）接收具有包括音素和音素持续时间信息的语音的音素边界信息的声道信息，（ii）使用音素边界信息应用于声带信息中的元音的声道信息的时间变化近似 第一功能，（iii）近似在应用第二功能的目标元音声道信息保持单元中保持的同一元音的声道信息的时间变化，（iv）通过将第一功能与第二功能组合来计算第三功能 （v）转换使用第三功能的元音的声道信息; 以及使用所转换的信息合成语音的合成单元。
