Speech Synthesis

Also known as: Text-to-speech, TTS

Converting written text into spoken audio with natural prosody and timing.

What Speech Synthesis is

Neural text-to-speech closed most of the gap with human recording, adding control over pace, emphasis and emotion.

How it works

Text is normalised and converted to phonetic and prosodic representations, a neural model produces an acoustic representation, and a vocoder renders the waveform. Streaming models generate audio fast enough for live conversation.

Why it matters

It is the output half of every voice assistant and a core accessibility technology.
