Models and voices

Every agent picks three things independently, from a catalog of providers:

• a language model, which decides what to say
• a transcriber (speech-to-text), which hears the caller
• a voice (text-to-speech), which speaks the reply

You are not locked to one vendor for all three, and you can change any of them without touching the prompt.

Defaults

An agent works without choosing anything: each stage falls back to a platform default. Change them on the agent's settings when you have a reason to - a cheaper model, a better voice for a language, a transcriber that handles your accents.

Language model

model.provider and model.model pick the model. temperature controls how varied the replies are.

Transcriber language

transcriber.language defaults to multi, which auto-detects. Leave it there unless you are certain every caller speaks one language.

A fixed, wrong language is the single most common cause of misheard names and numbers, and of keyword routing that never matches - the agent is being told to hear a language the caller is not speaking.

Voice

Pick the provider and the voice. Available voices come from the provider, so the list changes with the provider you choose.

Bring your own keys

You can use your own account with any provider. Add the key once under credentials and agents will use it instead of the platform's.

When a provider runs on your key, that provider's cost is yours and Glytos does not charge for it. The platform fee still applies to the call. See Pricing and credits.
