1. Note that currently only the speech synthesis part is available in Firefox Desktop — the speech recognition part will be available soon, once the required internal permissions are sorted out.

2. From version 44: this feature is behind the media.webspeech.recognition.enable preference (needs to be set to true). To change preferences in Firefox, visit about:config.
