Keyterm Filtering for Voice AI
Technical Positioning
A solution to reduce keyterm hallucinations in Speech-to-Text (STT) transcripts, specifically for non-English languages and non-standard accents, improving accuracy where existing providers like Deepgram fail.
SaaS Insight & Market Implications
This product addresses a critical accuracy gap in voice AI, specifically for non-English and accented English STT. Current STT providers struggle with keyterm hallucination, leading to incorrect transcripts. This directly impacts data quality for downstream applications relying on voice data, such as customer service analytics or content moderation. The 60% reduction in hallucinations on test data suggests a significant improvement in data fidelity. The focus on Hindi and Indian-accented English highlights a specific, underserved market segment with high growth potential for voice-enabled services. Offering streaming and self-hosting options indicates an understanding of enterprise deployment requirements, positioning it as a valuable component for businesses building robust, multilingual voice AI solutions. This targets a clear developer pain point: unreliable STT output for specialized terminology and diverse linguistic inputs.

Show HN: Keyterm Filtering for Voice AI
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.
