Acoustic Voice Analysis Online — a Praat Alternative
Praat is the reference tool for acoustic analysis, but its scripting workflow is a barrier for many busy clinicians. Vocametrix provides the same core acoustic measures — AVQI, CPP, jitter, shimmer, HNR, formants, breathiness and more — through a guided online interface, with no scripts to install, edit or maintain.
Open the online voice analysis tool →What you can measure
Overall voice quality (AVQI), cepstral peak prominence (CPP), harmonics-to-noise ratio (HNR), jitter and shimmer, formant frequencies, breathiness (ABI) and voice range (ambitus) — each computed automatically from your recording.
Built for speech-language pathologists
Record or upload audio, get reproducible measures, and export them straight into your clinical notes. The tools were designed with input from practising speech therapists to fit real assessment workflows.
Frequently asked questions
Is Vocametrix a replacement for Praat?
Vocametrix is not Praat, but it reproduces the most commonly used acoustic voice measures through a guided online interface, so most clinicians no longer need to write or maintain Praat scripts for routine assessment.
Do I need to install anything?
No installation or scripting is required for the online tools — you work directly in the browser-based platform.
