AssemblyAI builds advanced speech language models that power next-generation voice AI applications. Its industry-leading speech-to-text delivers highly accurate transcription along with speaker detection, summarization, PII redaction, and an LLM gateway.

The Universal-3 Pro Streaming model is the most accurate real-time STT model for voice agents with entity detection, speaker labels, and code switching capabilities. It's built specifically for handling challenging scenarios like disfluencies, alphanumerics, and noisy environments. The platform offers both async and real-time streaming support with features including sentiment analysis, content moderation, and multilingual support across 99+ languages.

The Universal-3 Pro Streaming is a first-of-its-kind realtime Speech Language Model built for the hard stuff voice agents actually encounter, including disfluencies, emails, URLs, names, account numbers, alphanumerics, and code-switching across languages. It operates effectively in noisy conditions while maintaining super low latency.

Developers can easily integrate AssemblyAI into AI notetakers, voice agents, AI medical scribes, call analytics tools, and more. The platform solves common voice agent failures that cluster around edge cases like incorrect credit card numbers, turn detection cutting off customers mid-sentence, and speaker labels scrambled in multi-party calls.

The product targets developers building voice AI applications and offers a comprehensive API with clear documentation and simple setup. It provides scalable real-time performance for applications requiring accurate speech recognition and audio intelligence features.
