AssemblyAI

Developers building voice features can use AssemblyAI through its AI models for automatic speech recognition and natural language processing.

AssemblyAI is a speech-to-text and transcription service that turns spoken audio into text and pulls insights out of voice data.

It sits in the AI developer tools space, so the audience is teams writing code that needs to handle audio, not people looking for a standalone transcription app.

The platform covers three areas: speech-to-text for recorded audio, streaming speech-to-text for audio as it arrives, and speech understanding for working with what was said once it has been transcribed.

That split is useful if your product needs both batch jobs and live transcription from one vendor.

AssemblyAI targets startups and enterprises alike.

Pricing follows an enterprise model, so expect to talk to the company rather than pick a plan off a page.
