Speech synthesis is a technology that generates artificial speech by mechanical and electronic means, and TTS technology (also known as text-to-speech conversion technology) is part of speech synthesis, which is a technology that transforms textual information generated by a computer itself or by external input into an understandable and fluent spoken output.
TTS speech synthesis technology is one of the key technologies to realize human-computer speech communication. Computers with human-like speaking ability are an important competitive market for the information industry in this era. Compared with speech recognition ASR, the technology of speech synthesis is relatively more mature and is a technology with a wider range of applications.
With the rapid development of artificial intelligence industry, speech synthesis system has been more widely used. In addition to the initial clarity and intelligibility of speech synthesis, people have higher and higher requirements for the naturalness, rhythm and sound quality of speech synthesis. The quality of speech library is also a key factor to determine the effect of speech synthesis.
