What is Text-to-Speech
Converting text to natural speech
Text-to-Speech (TTS) is a technology that converts text into natural human speech using artificial intelligence.
How TTS Works
- Text analysis — parsing sentences, determining pauses and intonations
- Phonetic conversion — translating letters into sounds (phonemes)
- Prosody — adding stress, tempo, emotional coloring
- Audio generation — synthesizing the final audio signal
Synthesis Technologies
- Concatenative — splicing recorded speech fragments
- Parametric — mathematical voice modeling
