## Definition

Text-to-speech (TTS) is AI technology that converts written text into spoken audio, generating natural-sounding human voices from text input for use as voiceover in video and audio production.

## Extended Definition

Modern AI text-to-speech has reached a quality level where synthetic voices are largely indistinguishable from human recordings at normal listening speeds. Leading TTS providers including ElevenLabs, Murf, Play.ht, and OpenAI TTS offer voice cloning (replicating a specific person's voice from a sample), emotion and tone control, pacing adjustment, and multilingual support. In video production, TTS enables creators to generate professional voiceover from a script in seconds, without recording equipment or on-camera presence. This is foundational for faceless video workflows, multilingual dubbing, and content scaling. The choice of voice, pacing, and emphasis directly affects viewer engagement, so creators typically test multiple voices and adjust pronunciation manually for technical terms. BlitzReels integrates TTS into its video generation pipeline, allowing voice selection alongside visual and caption configuration.
