NeuroVocal Studio — Voice analyzer

Your voice says more than you think

Every sentence you speak carries dozens of signals the ear can't catch: micro-shifts in rhythm, tension, hesitation. NeuroVocal Studio listens for them and turns any recording into a clear verdict — no weird spectrograms, and your voice never leaves your phone.

Record or importAudio or video, it doesn't matter: the analysis comes back instantly.

A verdict, not chartsNo raw data dumps: it tells you what it found, in plain language.

Watch it liveAlerts evolve along the timeline as you play back — you see the hot moments of the speech.

Your voice stays with youAll analysis happens on your device. Nothing travels to any server.

🔧 For the curious: how it works insideThe analysis engine, explained — only if you feel like diving in▾

At its heart is an analysis engine with variable-by-variable fusion and a lightweight machine-learning layer — designed to run entirely on the device, never sending audio to a server.

Acoustic feature extraction. Multiple dimensions are pulled from the signal: pitch and its behavior, energy, rhythm, pauses, and micro-variations beyond human hearing.

Variable-by-variable fusion. Each variable is scored and weighted separately before combining — instead of one opaque index, the verdict is built piece by piece, making it more robust to noisy recordings.

Light ML layer. A compact model interprets the whole and produces the final verdict with its intensity level — small enough to run instantly on a phone.

Synchronized timeline. Results are mapped onto playback, so alerts evolve with the speech instead of collapsing into a single final number.
