Pitch Visualizer

Pitch and resonance visualization for clinical documentation

Measures

Pitch (F0): Contour, distribution, mean, and range

Formants (F1, F2, F3): Vowel-specific resonance analysis — requires Sustained Vowel Mode

Reference bands: Adult speaking pitch ranges (Baken & Orlikoff 2000) and vowel-keyed F3 zones (Hillenbrand 1995)

Musical scale reference: Note-to-frequency mapping

Recording Tips for Best Results

What to Record

Natural speech or reading aloud (10-15 seconds), or sustained vowel (3-5 seconds)

Environment

Quiet room, normal speaking volume

What to Avoid

Singing, whispering, shouting, background noise

Any Device Works

Phone, computer, or any recording app

Want Formant Analysis (F1, F2, F3)?

After uploading a sustained vowel recording (/a/, /i/, or /u/), enable "Sustained Vowel Mode" before clicking Analyze. This extracts formant frequencies for resonance assessment.
