AssemblyAI launches Voice Agent API with flexible integration options

By PulseAugur Editorial · [1 sources] ·

AssemblyAI has introduced its Voice Agent API, offering two integration lanes for voice AI stacks. The first lane, Voice Agent API, is a fully managed service handling speech-to-text, LLM routing, and text-to-speech. The second lane, Universal-3.5 Pro Realtime, allows developers to integrate AssemblyAI's STT model into their existing infrastructure, preserving their current LLM, TTS, and orchestration logic. This approach aims to improve transcription accuracy for critical data like names and numbers, offering features such as agent context, conversation memory, and multi-language support. AI

IMPACT Enables developers to integrate advanced STT capabilities into existing voice AI stacks without full rebuilds, potentially improving accuracy for critical data.
