A voice analysis tool is software that measures the acoustic properties of your voice from an audio recording. Instead of a subjective opinion, it produces objective numbers — a voice score — that describe how healthy, clear, and stable your voice sounds.
How does a voice analysis tool work?
When you analyse your voice with an online tool like My Voice Score, it runs through four stages:
- Audio capture: You upload a recording or record directly in the browser.
- Voice activity detection: Silence and background noise are removed so only speech is analysed.
- Acoustic feature extraction: The engine (built on the research-grade Praat library) measures pitch, jitter, shimmer, harmonics-to-noise ratio (HNR), and cepstral peak prominence (CPPS).
- Scoring: Those raw features are converted into easy-to-read 0–100 scores for voice health, vocal fatigue, clarity, and communication.
What can a voice scoring tool measure?
- Voice health — overall vocal wellness
- Vocal fatigue — signs of tiredness or strain
- Hoarseness & roughness — breathiness and irregularity
- Clarity & articulation — how intelligible your speech is
- Communication score — pace, fillers, and expressiveness
Who uses voice analysis tools?
Singers, teachers, podcasters, call-centre agents, and public speakers use them to monitor vocal load. Speech-language pathologists (SLPs) and voice therapists use them for screening and tracking therapy progress.
Is it a medical diagnosis?
No. A voice analysis tool is a screening and self-monitoring aid. It highlights acoustic patterns often linked to vocal issues, but it does not replace evaluation by a qualified clinician. See our medical disclaimer.
