Keyterm prompting is a valuable way to help your STT better recognize unique terms like brand names etc, but for non-English languages/non-standard accents, providers like Deepgram tend to hallucinate keyterms in STT transcripts. So the output transcript contains the given keyterms, even when those keyterms are not present in the input audio.

I'm currently collecting feedback to improve this product. Right now it cuts down keyterm hallucinations by about 60% on in-house test data, so I'm curious to see how it performs in public.

The product is free to use while in beta (Hindi and Indian-accented English are supported). Would love to hear how it performs on your data. Feel free to drop a comment if you’re interested in features like additional language support, streaming and self-hosting.
