SpeechRecognition extension type

The SpeechRecognition interface of the Web Speech API is the controller interface for the recognition service; this also handles the SpeechRecognitionEvent sent from the recognition service.

Note: On some browsers, like Chrome, using Speech Recognition on a web page involves a server-based recognition engine. Your audio is sent to a web service for recognition processing, so it won't work offline.

Properties

continuous ↔ bool
The continuous property of the SpeechRecognition interface controls whether continuous results are returned for each recognition, or only a single result.
getter/setter pair
grammars ↔ JSObject
The grammars property of the SpeechRecognition interface returns and sets a collection of SpeechGrammar objects that represent the grammars that will be understood by the current SpeechRecognition.
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
interimResults ↔ bool
The interimResults property of the SpeechRecognition interface controls whether interim results should be returned (true) or not (false). Interim results are results that are not yet final (e.g. the SpeechRecognitionResult.isFinal property is false).
getter/setter pair
lang ↔ String
The lang property of the SpeechRecognition interface returns and sets the language of the current SpeechRecognition. If not specified, this defaults to the HTML lang attribute value, or the user agent's language setting if that isn't set either.
getter/setter pair
maxAlternatives ↔ int
The maxAlternatives property of the SpeechRecognition interface sets the maximum number of SpeechRecognitionAlternatives provided per SpeechRecognitionResult.

Methods

abort() → void
The abort() method of the Web Speech API stops the speech recognition service from listening to incoming audio, and doesn't attempt to return a SpeechRecognitionResult.
addEventListener(String type, EventListener? callback, [JSAny options]) → void
The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
inherited
dispatchEvent(Event event) → bool
The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeEventListener(String type, EventListener? callback, [JSAny options]) → void
The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.
inherited
start() → void
The start() method of the Web Speech API starts the speech recognition service listening to incoming audio with intent to recognize grammars associated with the current SpeechRecognition.
stop() → void
The stop() method of the Web Speech API stops the speech recognition service from listening to incoming audio, and attempts to return a SpeechRecognitionResult using the audio captured so far.
toString() → String
A string representation of this object.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
