The phrase read-only property of the SpeechRecognitionPhrase interface returns a string containing the word or phrase you want boosted in the recognition engine's contextual bias.
A string.
The SpeechRecognition.phrases property holds an array of SpeechRecognitionPhrase objects representing contextual biasing phrases. This array can be modified just like a normal JavaScript array, for example by pushing new phrases to it dynamically:
recognition.phrases.push(new SpeechRecognitionPhrase("thistle", 5.0));You can then access these objects and their properties like so. To return the phrase value of the added phrase, you could do this:
// Should return "thistle"
recognition.phrases[0].phrase;
