Voca is a speech and audio viewer for Chromebooks and Chrome/new Edge browser. Voca displays the sound coming into the microphone graphically on the screen. Available viewing option are: spectrogram, frequency display, waveform and audio volume history. This tool is useful for encouraging speech and seeing different patterns generated by different sounds.
Voca is also available as a Web App for use in Chrome browser on all platforms. Launch it from the icon below in a new tab.
The Voca app is not currently supported by iOS/Safari so sadly won’t run on an iPad or iPhone. On MacOSX it will run if Chrome browser or new Edge browser is installed and used to launch the app.
It is possible to license the Sensory Web Apps to run from your own servers. Please contact us at [email protected] if you would like to license the web apps for use on your network or in your application.
