Currently only English command processing is supported. To activate, you need to click on the indicator in the address bar and issue a voice command (the microphone is disabled in the background).
The proposed add-on differs from typical voice control systems in that it is not focused on replacing the mouse and keyboard when manipulating the interface, but is positioned as an auxiliary tool for processing questions in natural language, acting as a voice assistant. For example, the user can send commands such as "what's the weather like now", "find the Gmail tab", "mute", "save as PDF", "zoom in", "open the mozilla website".
After installing the add-on, the user is prompted to grant the right to collect and analyze voice patterns, with their transfer to Mozilla servers to increase the accuracy of the service (the data is collected anonymously and is not transferred to third parties). At the same time, sending telemetry with voice data is optional and can be refused.
On editions of soeren-hentzschel.at, the commands are processed using the Google Cloud Speech Service, but in the add-on code Mozilla servers (settings can be overridden on build). In the file that defines the privacy policy, the ability to send voice data to both Mozilla and Google Cloud Speech.
