Setting this is good practice, and therefore recommended.

SpeechRecognition.lang: Sets the language of the recognition.

ntinuous: Controls whether continuous results are captured ( true), or just a single result each time recognition is started ( false).We also set a few other properties of the recognition instance before we move on: We then add the SpeechGrammarList to the speech recognition instance by setting it to the value of the ammars property. We also create a new speech grammar list to contain our grammar, using the SpeechGrammarList() constructor. This is done using the SpeechRecognition() constructor. The next thing to do is define a speech recogntion instance to control the recognition for our application. Plugging the grammar into our speech recognition For this basic demo, we are just keeping things simple. You can have as many terms defined as you want on separate lines following the above structure, and include fairly complex grammar definitions.Note how each is separated by a pipe character.

public declares that it is a public rule, the string in angle brackets defines the recognized name for this term ( color), and the list of items that follow the equals sign are the alternative values that will be recognized and accepted as appropriate values for the term. The second line indicates a type of term that we want to recognize.The first line - #JSGF V1.0 - states the format and version used.The lines are separated by semi-colons, just like in JavaScript.However, for now let's just run through it quickly: The grammar format used is JSpeech Grammar Format ( JSGF) - you can find a lot more about it at the previous link to its spec. Var colors = var grammar = '#JSGF V1.0 grammar colors public = ' + colors.
