AssemblyAI

With AssemblyAI's industry-leading Speech AI models, transcribe speech to text and extract insights from your voice data

AssemblyAI provides speech AI models and APIs that developers use to transcribe speech to text and extract insights from voice data. The site positions it as voice AI infrastructure for builders, with models, APIs, and infrastructure in one place so voice can be added to any product on any stack.

The product line splits into transcription (pre-recorded, real-time, and sync speech-to-text APIs), understanding (a speech understanding API, guardrails and safety, and an LLM gateway), interaction (a voice agent API and a dictation API), and inference (self-hosted or cloud). The dictation API returns text that is ready to send, with filler removed, self-corrections resolved, and names spelled correctly. Use cases listed include voice agents, AI notetakers, call analytics, medical transcription, agent assist, and AI scribes, with support for 99 languages. Developers get documentation, an API reference, cookbooks, a changelog, a status page, and a playground. In this directory it appears under Music & Audio with a transcriber tag.

Pricing is published on a dedicated page but not detailed here, and the site offers a get-started path alongside a contact option. Try the playground first to test a transcript before integrating the API.
