Fast, scalable speech-to-text and voice AI APIs
Deepgram is one of the strongest developer-first speech APIs on the market, with excellent per-minute economics, fast streaming, and a broad feature set including diarization and keyterm prompting. It is aimed squarely at developers, so non-technical users will find little to use directly. Pricing is transparent and usage-based, and the free $200 in credits makes it easy to evaluate. For production voice apps at scale, it is a top contender.

Speech AI models and APIs for developers
AssemblyAI is a polished, accuracy-focused speech API with a rich set of audio-intelligence features and strong developer experience. It is a close competitor to Deepgram; the right choice usually comes down to your accuracy needs, feature mix, and pricing at your volume. It is developer-only, so non-technical users won't use it directly. The free tier is generous enough to evaluate thoroughly before committing.
