Frequently Asked Questions

What exactly does voice and speech synthesis technology do and what are its basic principles?

Voice and speech synthesis is a technology that converts written text into human-like audio. Its basic principles include text analysis, phonetic transformation, and acoustic modeling. The text is first analyzed to decipher its grammatical structure and meaning. Then, using this information, the words in the text are converted into basic sound units called phonemes. Finally, acoustic modeling synthesizes these phonemes to produce a vocal output that is similar to the human voice.

How far back does voice and speech synthesis technology go, and what significant milestones have been achieved along the way?

The origins of voice and speech synthesis technology are quite old. The first mechanical speech devices date back to the 18th century. However, modern speech synthesis studies began in the mid-20th century. Important milestones include formant synthesis, articulatory synthesis, unit selection synthesis, and finally the development of deep learning-based neural TTS (Text-to-Speech) systems. Each stage has contributed to the production of more natural and understandable voices.

What are the most advanced voice and speech synthesis methods used today and what are the advantages of these methods over others?
