What is Text-to-Speech (TTS) ?

TTS is an acronym for text to speech. It is a machine speaking technology, or speech synthesis technology. It is a part of man-machine dialogue, allowing machines to speak. Designed to intelligently convert text into natural speech.

TTS steps

  1. Text processing
    Converting the text into a phoneme sequence, and marking the start and end time, frequency change and other information of each phoneme, as an important preprocessing step, it involves many issues worthy of research, such as part of speech distinction, abbreviation processing, etc.

  2. Speech synthesis
    Convert information such as phoneme sequences into speech based on neural networks.

Application scenarios of TTS

  1. Robot voice
    In scenarios such as customer service robots and service robots, it can be combined with speech recognition, natural language processing and other modules to realize high-quality robot voices and make human-computer interaction more smooth and natural.

  2. Make an audiobook
    Import text materials such as electronic textbooks and novels into the speech synthesis engine in the form of text files to generate complete and rereadable audio textbooks or audio novels, which are convenient for users to use at any time.

  3. Voice broadcast
    In voice navigation applications and news apps, speech synthesis can quickly generate high-quality broadcast audio, which is convenient for users to use audio to obtain information in a timely manner when it is inconvenient for users to read messages such as walking or driving.
