Voice-Analysis API Development for Companies & Universities — Speech Analysis APIs & Clinical Voice Tools

We Help Companies and Universities Build Voice-Analysis APIs

Vocametrix's core business is partnering with companies and universities to design, prototype, and industrialize voice-analysis APIs and speech-technology products. Whether you are a startup adding vocal biomarkers to a health product, an enterprise integrating speech metrics into an existing platform, or a university lab turning research pipelines (Praat, eGeMAPS, custom acoustic features) into production-grade APIs, we co-develop the solution with you — from endpoint design and audio processing to deployment, documentation, and maintenance.

What can you actually ask?

Asked by: Speech Therapist
"Analyze this voice recording and give me jitter, shimmer, and HNR values."

Illustrative response — not a real analysis or clinical recommendation:

Jitter: 0.42 % (normal range) · Shimmer: 3.1 dB (slightly elevated) · HNR: 18.2 dB. The shimmer value suggests mild vocal irregularity. I recommend a follow-up comparison in 4 weeks.
