We use the HTMLSelectElement selectedOptions property to return the currently selected element. Next, we need to figure out which voice to use. We first create a new SpeechSynthesisUtterance() instance using its constructor - this is passed the text input's value as a parameter. We are using an onsubmit handler on the form so that the action happens when Enter/ Return is pressed. Next, we create an event handler to start speaking the text entered into the text field. onresult = function ( event ) Speaking the entered text But it is not needed for this simple demo, so we are just specifying one (which is actually the default anyway.) This can sometimes be useful, say if a result is not completely clear and you want to display a list if alternatives for the user to choose the correct one from.
SpeechRecognition.maxAlternatives: Sets the number of alternative potential matches that should be returned per result. Final results are good enough for this simple demo. SpeechRecognition.interimResults: Defines whether the speech recognition system should return interim results, or just final results. 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 recognition 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. Connecting via mobile or Wi-Fi expands the accuracy and capability.Const colors = const grammar = '#JSGF V1.0 grammar colors public = ' + colors. This is in stark contrast to Google’s mobile OS Android, which has had deep voice integration for years, and can transcribe “okay, Google” commands even without a data connection. Dictation outside of Google Docs currently requires third-party extensions. While Google Docs can do voice dictation, it requires an active data connection, and even that capability isn’t extended to other text entry points on an OS level. Exactly when the feature will be ready for end users, even in the preview canary builds, isn’t available at this time. CHROME SPEECH TO TEXT OFFLINE
The flags are listed as “Experimental accessibility dictation extension” and “Experimental accessibility dictation offline.” There’s also a bug tracking entry that mentions offline speech recognition. The Chrome Story blog spotted two flags in a canary (alpha) build that indicate that system-wide voice dictation is coming, even when the device is offline.

A recent update to the Chrome OS code indicates that they might get even more friendly.

Chromebooks often appeal to first-time computer buyers, or those who find Windows or MacOS too intimidating.
