Voice Gender

Voice Gender is an AI-powered audio analysis tool that examines vocal recordings for gender-associated acoustic patterns. Record a sample or import an audio file and the app analyzes characteristics like fundamental frequency, formant patterns, and speech rhythm to produce a vocal profile.

The app is designed as a research and exploration tool, useful for voice training, linguistics study, and understanding how AI approaches vocal analysis. Results include a breakdown of the acoustic features examined and how each contributes to the overall assessment. It is educational rather than definitive.

Voice Gender is a practical utility for anyone curious about voice science, working on voice training goals, or exploring how AI interprets acoustic signals.

What Voice Gender Analyses

📊 Fundamental Frequency (F0)

The pitch of a voice — its fundamental frequency — is one of the primary acoustic markers that differs across vocal presentations. Voice Gender measures your average F0, your pitch range, and your pitch variability across a sample, displaying results as a frequency histogram alongside reference ranges.

🎵 Formant Patterns

Formants are resonant frequencies produced by the shape and length of the vocal tract. Voice Gender analyses F1, F2, and F3 formant values — patterns that contribute significantly to perceived vocal quality and gender presentation — and displays them against established phonetic benchmarks.

🔊 Resonance and Timbre

Beyond raw frequency, Voice Gender evaluates resonance placement (chest vs. head resonance), harmonic-to-noise ratio (an indicator of vocal clarity), and spectral tilt. These factors influence how a voice is perceived in terms of warmth, brightness, and authority.

Use Cases

Voice Training

Voice coaches and their clients use Voice Gender to track measurable progress. By comparing recordings over weeks or months, you can see exactly how pitch range, formants, and resonance shift as training progresses — turning subjective impressions into objective data.

Voice Acting and Performance

Performers exploring character voices use Voice Gender to understand the acoustic difference between various vocal presentations, giving them a technical reference point to recreate specific qualities consistently.

Academic and Linguistic Research

Students and researchers studying phonetics, sociolinguistics, or gender and language use Voice Gender as a lightweight field tool for collecting and comparing vocal samples.

Privacy

All audio analysis is performed on-device. Voice recordings are never stored on external servers or shared with third parties. See the privacy policy for full details.
