Understanding Voice Pitch
Vocal pitch is determined by the rate at which your vocal folds vibrate, measured as fundamental frequency (F0) in Hertz (Hz). Research on speaking fundamental frequency shows that typical masculine voices average around 120 Hz, while feminine voices average around 210 Hz. The range between 155–165 Hz is often described as androgynous.
Voice training works by building new muscle memory in the larynx and vocal tract. Consistent practice with real-time feedback helps develop awareness of pitch, resonance, and intonation patterns. Voice Whiz provides this feedback by displaying your F0 as a live graph while you speak.
For more on voice science and clinical approaches to voice training, see resources from the American Speech-Language-Hearing Association (ASHA) and published research such as Titze, I.R. (1994), Principles of Voice Production.
Note: Voice Whiz is a voice analysis tool, not a medical device. It does not replace professional speech therapy. For clinical voice concerns, consult a certified speech-language pathologist.
