What Is Text-to-Speech (TTS)?
Definition
Text-to-speech is an AI technology that converts written text into natural-sounding spoken audio. Modern TTS systems use neural networks to produce speech that closely mimics human intonation, rhythm, and emotion, moving far beyond the robotic voices of earlier systems.
How It Works
Modern TTS systems use transformer-based neural networks trained on thousands of hours of human speech. The text is first converted into phonemes, then a neural vocoder generates the audio waveform. Advanced systems support multiple voices, emotions, and speaking styles. In the dubbing context, TTS is the engine that generates the translated audio — but standalone TTS tools like ElevenLabs produce audio only, without video output or lip sync.
