Methods
-
addEventListener(
String type, EventListener? callback, [JSAny options]) → void -

addEventListener()
method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.inherited -
cancel(
) → void -
The
cancel()
method of the SpeechSynthesis interface removes all utterances from the utterance queue. -
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 withdispatchEvent()
.inherited -
getVoices(
) → JSArray< SpeechSynthesisVoice> -
The

-
pause(
) → void -
The
pause()
method of the SpeechSynthesis interface puts theSpeechSynthesis
object into a paused state. -
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 -
resume(
) → void -
The
resume()
method of the SpeechSynthesis interface puts theSpeechSynthesis
object into a non-paused state: resumes it if it was already paused. -

SpeechSynthesisUtterance utterance) → void -
The
speak()
