AssemblyAI, a company best known for speech-to-text APIs, has introduced its first text-to-speech model, AssemblyAI-TTS-1. The service is priced at $15 per 1 million characters and supports six languages at launch, positioning it for developers building voice agents.
The API offers unlimited concurrency without requiring a contract, a pricing structure aimed at startups and enterprises that need scalable voice output. By entering the TTS market, AssemblyAI is expanding beyond transcription to cover the full speech pipeline, from understanding spoken input to generating natural responses.
This move intensifies competition in the voice AI space, where low-cost, high-concurrency TTS is increasingly critical for real-time agent applications. AssemblyAI's existing developer base could give it an advantage in cross-selling the new model alongside its established STT offerings.
