I want to measure the voice frequency in Hz. Is there any open source or tool available in Ubuntu?

This list is by no means exhaustive:

Spek - helps to analyse your audio files by showing their spectrogram. Perhaps the easiest for novice users and available from the Software Centre.

Audacity - the reference audio editor for Linux, but with a complex user interface; also available from the Software Centre.

JAAA - audio signal generator and spectrum analyser designed to make accurate measurements; available from the Software Centre.

Spectrum3d - an audio spectrum analyser in 3D for Linux; works in real time from the mic or in non-real time from an audio file.

Toscanalyzer - among many other features: frequency band analysis on 4 bands and sub-band; frequency band distribution in stereo space; representation of spectrum with frequency and tonal scaling.

SoundRuler - a tool for measuring and graphing sound and for teaching acoustics.

Spectrum Analyzer - an oldie programmed for DOS that is supposed to run on Wine.

i am asking the speaking frequency. ie., i am recording my voice using mic. i saved this file, might be mp3 or wav format. i get the frequency range from this stored file. how to i get it? –  Muthu Aug 20 at 5:31
    
I do not fully understand, once you have the spectrogram what else do you wish to get? –  Luís de Sousa Aug 20 at 7:02
    
I am trying to measure the pitch of a human voice. I believe it is measured in frequencies. So how do I measure the frequency of a human voice? Do I record a person reciting the vowels in their regular voice? How do I label the voice as low, medium, high pitch based on the frequencies? –  Muthu Aug 20 at 7:37

These later questions of yours are not related to any software, much less to Ubuntu. I recommend the Physics site for that matter. –  Luís de Sousa Aug 20 at 7:56

A lightweight application which does just this is lingot.

Other options:

  • fmit - Free Music Instrument Tuner
  • gtkguitune - Guitar and other instruments tuner
  • gxtuner - Tuner for Jack
  • zita-at1 - JACK autotuner

Note: when you run lingot from within your Ubuntu desktop environment, set the audio device to pulse.
