The voice library — human-sounding synthetic speech, filterable by language and accent, and clonable from your own audio.

Pick this when

The voice itself is the product decision: you want a specific accent, gender or a cloned voice rather than a stock one.

What makes it different

Filterable library (English, British, male…) with a voice ID you paste straight into Retell

Voice cloning from roughly 20 minutes of audio

Multilingual voice tags for agents that must switch language

What it does

Generates human-like speech in many voices and languages

Supplies voice IDs to voice-agent platforms as a custom provider

Clones a voice from a sample

What it does not do

Common wrong expectations

Doesn't build the agent — it supplies the voice the agent speaks in

Where it sits in a stack

The voice layer of any phone or audio agent; billing unifies with the platform that calls it.

None currently — though a spoken summary of a session page is a plausible accessibility idea if audio ever becomes interesting.
