Short answer

Text-to-speech (TTS) converts written text into spoken audio using generative speech models for accessibility, assistants, and media.

Why it matters

Good TTS unlocks inclusive products; voice cloning extensions require consent and fraud awareness.

Policy

Ban cloning executives without written approval.

Examples

Course narration

An instructor pastes lesson text, selects a calm voice, exports MP3, then manually fixes chapter titles misread as acronyms using a pronunciation lexicon.

IVR prompts

A support system generates dynamic balance-readout prompts with SSML for currency amounts, keeping latency low via streaming synthesis.

FAQ

What is SSML?
Speech Synthesis Markup Language is a markup format some TTS engines support to control pauses, say-as interpretation, pitch, and other pronunciation details beyond plain text.
Why does TTS mispronounce names?
Names and brand terms are long-tail linguistic items. Custom lexicons, phonetic spellings, or SSML phonemes often fix recurring errors.
Is streaming TTS different from batch?
Streaming synthesizes and delivers audio chunks with lower time-to-first-byte for interactive apps. Batch generation optimizes for full-file quality/throughput in offline workflows.
