AssemblyAI

AssemblyAI provides industry-leading Speech AI models—like its Universal model with >93.3% accuracy—via a developer-first API for transcription and deep audio intelligence.

AssemblyAI is the premier Speech AI platform, delivering state-of-the-art models for both high-accuracy transcription and deep audio understanding (Speech-to-Text and Audio Intelligence). Developers access this power through a robust, scalable API, integrating features like real-time streaming with <500ms latency. The platform goes beyond raw text: models like LeMUR apply LLMs to transcribed speech for automatic summarization, sentiment analysis, and PII redaction. Major companies, including CallRail, Fireflies, and Spotify, rely on AssemblyAI to build cutting-edge, voice-powered products and extract actionable insights from conversational data.
