What it is
AssemblyAI LeMUR (Large Model Untouched by Rules) is a framework that lets developers query LLMs over AssemblyAI transcripts — summaries, Q&A, action items — with a thin API. For voice-agent use cases it pairs naturally with AssemblyAI streaming ASR and external TTS to power workflows that are voice-in but mostly post-call analysis.
Watch out for: Built around post-call rather than ultra-low-latency realtime agents.
