Understanding your vocal frequency in Hz

What Hz measures

Hertz means cycles per second. In voiced speech, the vocal folds open and close in a repeating pattern. Its repetition rate is the fundamental frequency, often written F0. A detector estimates that rate from a short audio window. The perceived sensation related to F0 is pitch, but the two are not identical: context, hearing and the rest of the sound all influence perception.

How to read a measurement

Use the same comfortable phrase, microphone distance and room when comparing sessions. A median across several seconds is usually more useful than one instant. Normal speech moves up and down, so variation is expected. Basaltone analyzes audio locally in the browser during the public test and stores no recording through that test.

The limit of a single number

F0 does not measure resonance, formants, vocal weight, articulation or speaking pattern. It also cannot determine identity, health or whether a voice will be perceived in a particular way. Treat Hz as one repeatable training marker, not a diagnosis or a verdict.
