Detailed Description

Goal of this feature is to give with Fedora a voice control software in order to help users to interact with system. This feature may be also useful for people with phisical disabilities.

Already exists a good start point, an older gnome applet named Gnome Voice Control. It's based on CMU Sphinx and GStreamer.

Alternatively, there's also Simon Listens, a good project based on Qt.

Development of Gnome Voice Control is ended by some years, but Simon Listens it's currently developped.

I think both they are interesting.

This is only a proposal, my programming skills are weak.

Benefit to Fedora

This feature will provide a new, advanced interaction way and will enhance accessibility for people with disabilities.


I suppose the big work is to port old application source into new Gnome libraries (Gnome Voice Control isn't updated since 2007).

How To Test

Excluding hardware problems (audio cards), I think this feature needs only some usability tests.

User Experience

User could activate the option "Voice Control" from "Accessibility Applet", so it can start to give some voice commands to pc. Like "BROWSER, MAIL, POWER OFF, etc.."


Old Gnome-voice-control dependencies are (from original website): libwnck-dev, libatspi-dev, gnome-panel-dev, startup-notification-devel libtool gnome-common intltool cmusphinx3

Simon listens dependencies are (compiling from source): gettext gettext-kde kdeartwork kdelibs5-dev libxtst-dev libqt4-sql-sqlite libphonon-dev libattica-dev libattica0 zlib1g-dev

Contingency Plan

Leave this feature out of the release. No user impact.

Release Notes

Fedora now supports Vocal Control. Thanks to an advanced Voice Recognition software, Fedora can receive some simple commands directly from your voice.
