Notes

Partial support refers to some attributes missing.
Firefox currently has a media.webspeech.recognition.enable flag in about:config for this, but actual support is waiting for permissions to be sorted out.
Reported to be in development for Samsung Internet for GearVR, due Q1/2017
Edge and Opera appear to have support for the SpeechRecognition API but no events for it appear to fire.
Safari 14.1 and TP 119+ include prefixed support for webkitSpeechRecognition without support for SpeechGrammar or SpeechGrammarList. Siri needs to be enabled. Not available in SafariViewController and web apps added to Home Screen.

^* Partial support with prefix.
