AssemblyAI details Python WebSocket workflow for streaming text to speech

AssemblyAI published a Python tutorial on streaming text to speech over WebSocket connections, framing it as a workflow for voice agents rather than a simple file-generation task. The company said the approach is designed to handle three live-call problems that saved audio files do not solve: LLM replies that are still being generated, caller interruptions, and long-running sessions that must stay healthy throughout a conversation. According to the tutorial published on Wed, 28 Oct 2026, the AssemblyAI Text-to-Speech API supports three routes: HTTP for one-shot synthesis, WebSocket for a single session across a conversation, and an OpenAI-compatible speech endpoint. The post says the Python SDK gained text-to-speech support in release 1.8.2 and shows how to install it with pip, set ASSEMBLYAI_API_KEY, and call TextToSpeech.synthesize() to produce a WAV file.
