    • According to one embodiment, in a speech processing device, an extractor windows a part of the speech signal and extracts a partial waveform. A calculator performs frequency analysis of the partial waveform to calculate a frequency spectrum. An estimator generates an artificial waveform that is a waveform according to an interval between the pitch marks for each harmonic component having a frequency that is a predetermined multiple of a fundamental frequency of the speech signal and estimates harmonic spectral features representing characteristics of the frequency spectrum of the harmonic component from each of the artificial waveforms. A separator separates the partial waveform into a periodic component produced from periodic vocal-fold vibration as an acoustic source and an aperiodic component produced from aperiodic acoustic sources other than the vocal-fold vibration by using the respective harmonic spectral features and the frequency spectrum of the partial waveform.
    • 根据一个实施例,在语音处理设备中,提取器对一部分语音信号进行窗口并提取部分波形。 计算器执行部分波形的频率分析以计算频谱。 估计器产生人造波形,其是根据具有作为语音信号的基频的预定倍数的频率的每个谐波分量的音调标记之间的间隔的波形,并且估计表示频率的频谱特性的谐波谱特征 来自每个人造波形的谐波分量。 分离器将部分波形分离为由周期性声带振动产生的周期分量,作为声源,并且通过使用相应的谐波频谱特征和频谱的频谱,从除声带之外的非周期声源产生的非周期分量 部分波形。

    • According to one embodiment, a markup assistance apparatus includes an acquisition unit, a first calculation unit, a detection unit and a presentation unit. The acquisition unit acquires feature amount for respective tags, each of the tags being used to control text-to-speech processing of a markup text. The first calculation unit calculates, for respective character strings, a variance of feature amounts of the tags which are assigned to the character string in a markup text. The detection unit detects first character string assigned first tag having the variance not less than a first threshold value as a first candidate including the tag to be corrected. The presentation unit presents the first candidate.
    • 根据一个实施例,标记辅助装置包括获取单元,第一计算单元,检测单元和呈现单元。 采集单元获取各个标签的特征量,每个标签用于控制标记文本的文本到语音处理。 第一计算单元针对相应的字符串计算在标记文本中分配给字符串的标签的特征量的方差。 检测单元检测具有不小于第一阈值的方差的第一标签的第一字符串作为包括要校正的标签的第一候选。 演示单位呈现第一个候选人。
