Universal-3 Pro by AssemblyAI

Universal-3 Pro by AssemblyAI is a pioneering promptable Speech Language Model designed for developers needing highly accurate, context-aware speech-to-text transcription. It uniquely allows natural language prompts to guide the model before transcription begins, enabling customized outputs for specific domains like medical, legal, business, and customer intelligence. The model supports nuanced requirements such as preserving disfluencies, tagging non-speech audio, role-based speaker labeling, code-switching between languages, and producing both verbatim and clean transcripts, all without requiring custom model training.
