AssemblyAI is a speech AI platform for developers who need transcription and voice features without training their own models. The homepage lists pre-recorded, real-time, and sync speech-to-text APIs, a speech understanding API, a voice agent API, and a dictation API. It also lists a text-to-speech API as coming soon. The platform supports 99 languages and offers a self-hosted voice AI cloud. Pricing text says you can start free and pay as you go after that, with no commitments required.
