AssemblyAI has released AssemblyAI-TTS-1, its first text-to-speech model aimed at voice agents. The company says the model costs $15 per 1 million characters.

The API offers unlimited concurrency without requiring a contract. At launch it supports six languages, and the source does not list which ones.

## Why it matters if you build agents

Developers building voice agents get a per-character speech price and can run many simultaneous requests without signing a contract.

Before switching a voice pipeline to AssemblyAI-TTS-1, check whether the six launch languages cover your users.
