The addFromURI() method of the SpeechGrammarList interface takes a grammar present at a specific URI and adds it to the SpeechGrammarList as a new SpeechGrammar object.
Note that some speech recognition services may support built-in grammars that can be specified by URI.
addFromURI(src) addFromURI(src, weight)
A string representing the URI of the grammar to be added.
A float representing the weight of the grammar relative to other grammars present in the SpeechGrammarList. The weight means the importance of this grammar, or the likelihood that it will be recognized by the speech recognition service. The value can be between 0.0 and 1.0; If not specified, the default used is 1.0.
