As one of the most mature technologies for AI applications, intelligent voice technology is developing rapidly in the fields of smart home, smart vehicle, and smart wearables. In 2022, the scale of the global intelligent voice industry will reach 35.12 billion US dollars, maintaining a high growth rate of 33.1%. Speech synthesis, also known as Text to Speech (TTS) technology, is an important research direction in the field of speech processing, which aims to allow machines to generate natural and beautiful human speech. Speech synthesis technology can be applied to different scenarios alone, or it can be embedded into the overall solution of voice interaction as a tail link. Speech synthesis technology is internally divided into front-end and back-end. The front-end is mainly responsible for language analysis and processing of text, and its processing content mainly includes language, word segmentation, part-of-speech prediction, polyphonic word processing, prosody prediction, emotion, etc.
