摘要:

本文提出了一种可控的端到端的文本到语音(TTS)系统,以控制合成语音的语速(速度可控TTS; SCTTS)与作为一个额外的输入的语速水平值。该系统采用语速值(输入音素数量与输入语音长度之比)来控制语速。此外,所提出的SCTTS系统可以控制说话的速度,同时保留其他语音属性,如音高,通过采用全局风格令牌为基础的风格编码器。所提出的SCTTS不需要任何额外的训练有素的模型或外部语音数据库来提取音素级的持续时间信息,可以在一个端到端的方式进行训练。此外,我们对快速,正常和慢速语音的听力测试表明,SCTTS可以产生更自然的语音比其他音素持续时间控制方法,增加或减少持续时间在相同的速度为整个句子,特别是在慢速语音的情况下。

英文摘要:

This paper proposes a controllable end-to-end text-to-speech (TTS) system to control the speaking speed (speed-controllable TTS; SCTTS) of synthesized speech with sentence-level speaking-rate value as an additional input. The speaking-rate value, the ratio of the number of input phonemes to the length of input speech, is adopted in the proposed system to control the speaking speed. Furthermore, the proposed SCTTS system can control the speaking speed while retaining other speech attributes, such as the pitch, by adopting the global style token-based style encoder. The proposed SCTTS does not require any additional well-trained model or an external speech database to extract phoneme-level duration information and can be trained in an end-to-end manner. In addition, our listening tests on fast-, normal-, and slow-speed speech showed that the SCTTS can generate more natural speech than other phoneme duration control approaches which increase or decrease duration at the same rate for the entire sentence, especially in the case of slow-speed speech.
