摘要： A speech synthesis system receives symbolic input describing an utterance to be synthesized. In one embodiment, different portions of the utterance are constructed from different sources, one of which is a speech corpus recorded from a human speaker whose voice is to be modeled. The other sources may include other human speech corpora or speech produced using Rule-Based Speech Synthesis (RBSS). At least some portions of the utterance may be constructed by modifying prototype speech units to produce adapted speech units that are contextually appropriate for the utterance. The system concatenates the adapted speech units with the other speech units to produce a speech waveform. In another embodiment, a speech unit of a speech corpus recorded from a human speaker lacks transitions at one or both of its edges. A transition is synthesized using RBSS and concatenated with the speech unit in producing a speech waveform for the utterance.

摘要翻译： 语音合成系统接收描述要合成的话语的符号输入。 在一个实施例中，话语的不同部分由不同的来源构成，其中之一是从要说明建模语音的人说话者记录的语音语料库。 其他来源可以包括使用基于规则的语音合成（RBSS）产生的其他人类语音语料库或语音。 可以通过修改原型语音单元以产生上下文适合于话语的适应的语音单元来构建话语的至少一些部分。 该系统将自适应语音单元与其他语音单元连接起来以产生语音波形。 在另一个实施例中，从人类说话者记录的语音语料库的语音单元在其一个或两个边缘处缺少转换。 使用RBSS合成转换并与语音单元连接产生话语的语音波形。
