What is Text To Speech?

Text To Speech, also known as Text To Speech (TTS), is a technology that converts text into speech for output through computer technology. This technology can convert arbitrary input text information into standard smooth speech and read it out in real time, which is equivalent to installing an artificial mouth on the machine. Text To Speech involves many disciplines such as acoustics, linguistics, digital signal processing, and computer science. It is a cutting-edge technology in the field of Chinese information processing. Text To Speech technologies are mainly divided into two types: rule-based synthesis technologies and statistical-based synthesis technologies. Rule-based synthesis technology mainly uses Text To Speech rules and a speech feature library to convert text into speech output by writing rules. However, the synthesis sound quality and interactivity are poor, and the synthesis efficiency is high. Technology based on statistical synthesis uses a large amount of speech data for training to generate speech signals, and can adaptively learn and adjust speech characteristics. Therefore, the synthesis sound quality and interactivity are better, but the synthesis efficiency is lower. Text To Speech technology has a wide range of applications, including voice assistants, virtual anchors, voice advertisements, voice notifications and other fields. With the continuous development of technology, Text To Speech technology has begun to move towards industrialization, and large-scale application is just around the corner.

What are the advantages and disadvantages of language synthesis?

The advantages and disadvantages of language synthesis (usually referred to as Text To Speech, or Text-To-Speech, TTS) can be discussed from many aspects:

1. advantages

   1. Improve accessibility: For visually impaired people, Text To Speech technology can help them obtain information by listening, thereby greatly improving the convenience and accessibility of life.
   2. Enhance interactivity: In the field of human-computer interaction, Text To Speech enables machines to "speak" and enhances the user's interactive experience, such as intelligent voice assistants, voice navigation, etc.
   3. Improve work efficiency: In situations where a large amount of text is required to be converted to speech, such as reading documents, broadcasting news, etc., Text To Speech can greatly save time and improve work efficiency.
   4. Personalized customization: Modern Text To Speech technology supports the adjustment of multiple parameters such as timbre, speed, and intonation, and can be personalized according to user needs.
   5. Reduce costs: Text To Speech technology can significantly reduce costs compared to manual reading, especially where large-scale text to speech is required.

2. disadvantages

   1. Naturality issues: Although Text To Speech technology has made great progress, in some cases, synthesized speech may still sound less natural, especially when dealing with complex language structures and emotional expressions.
   2. Accent and dialect issues: Currently, most Text To Speech systems mainly support the pronunciation of standard Mandarin or other mainstream languages, with relatively limited support for dialects and special accents.
   3. Error Handling: When there are grammatical errors, spelling errors or special symbols in the input text, the Text To Speech system may not be able to process it correctly, resulting in problems with the output speech.
   4. Privacy and security issues: With the popularization of Text To Speech technology, how to protect users 'privacy and data security has become an important issue. For example, malicious users may use Text To Speech technology to fake other people's voices for fraudulent activities.
   5. Technical threshold: Although Text To Speech technology is relatively mature, its development and deployment still require certain technical thresholds and cost investment, which may limit the use of some small businesses and individual users.
