The free Report on six of the best voice analysis apps for Singing Teachers

There is a wide selection of voice analysis software available on the web that can be used to produce spectrograms. They have a range of features and most are available for free trial. Recently we asked our accredited teacher Anne Leatherland to check out some of the free and paid voice analysis apps for iPhone or iPad, and alternatives for Android. You can download the free Report here.

Below are some of the other voice analysis programmes I have tried out over the years.


Drew University Music Department LAS3 Lab.
A free version of this software, called ‘VoceVista – RealTime’ is available for download from the Vocalist web site. It’s a good program to start with if you’re learning about computer voice analysis and only takes a few minutes to download. The free version is limited to recording a maximum of eight seconds but does allow you to save examples. The fully featured version costs around $65. The Drew University Music Department has a web site with articles describing VoceVista’s use in the vocal studio (link below).
More information on the software is available from the VoceVista web site:
