What is AssemblyAI?
AssemblyAI provides AI models, APIs, and infrastructure for speech transcription and understanding. It is designed for development teams adding voice capabilities to products, with support for asynchronous processing, real-time interaction, and voice-agent workflows.
The platform exposes transcription, speech analysis, and voice-related capabilities through developer interfaces for applications such as meetings, customer service, media, and voice interaction. Implementation depends on the selected models, APIs, and product architecture. Its central role is to provide integrable speech AI.
