AssemblyAI has released a new Voice Agent API that simplifies the creation of real-time voice AI applications in Python. This API consolidates speech-to-text, LLM integration, text-to-speech, turn detection, and tool calling into a single WebSocket connection. The service is priced at a flat rate of $4.50 per hour, aiming to reduce the complexity and cost associated with building such systems. AI

AssemblyAI has released a Voice Agent API that allows developers to build sophisticated voice applications for specific industries. The API integrates speech-to-text, LLM, and text-to-speech capabilities into a single WebSocket, simplifying the development of complex conversational agents. This enables the creation of applications like telehealth triage systems that can capture patient symptoms and route them appropriately, or AI-powered cold-calling agents that qualify leads and book meetings, all while adhering to industry-specific compliance requirements.
