Interface SpeechRecognitionEvent

The SpeechRecognitionEvent interface of the Web Speech API represents the event object for the result and nomatch events, and contains all the data associated with an interim or final speech recognition result. Available only in secure contexts.

composedPath initEvent preventDefault stopImmediatePropagation stopPropagation
AT_TARGET: 2
bubbles: boolean

The bubbles read-only property of the Event interface indicates whether the event bubbles up through the DOM tree or not.

MDN Reference

BUBBLING_PHASE: 3
cancelable: boolean

The cancelable read-only property of the Event interface indicates whether the event can be canceled, and therefore prevented as if the event never happened.

MDN Reference

cancelBubble: boolean

The cancelBubble property of the Event interface is deprecated. Use Event.stopPropagation() instead. Setting its value to true before returning from an event handler prevents propagation of the event. In later implementations, setting this to false does nothing. See Browser compatibility for details.

MDN Reference

CAPTURING_PHASE: 1
composed: boolean

The read-only composed property of the Event interface returns a boolean value which indicates whether or not the event will propagate across the shadow DOM boundary into the standard DOM.

MDN Reference

currentTarget: EventTarget | null

The currentTarget read-only property of the Event interface identifies the element to which the event handler has been attached.

MDN Reference

defaultPrevented: boolean

The defaultPrevented read-only property of the Event interface returns a boolean value indicating whether or not the call to Event.preventDefault() canceled the event.

MDN Reference

eventPhase: number

The eventPhase read-only property of the Event interface indicates which phase of the event flow is currently being evaluated.

MDN Reference

isTrusted: boolean

The isTrusted read-only property of the Event interface is a boolean value that is true when the event was generated by the user agent (including via user actions and programmatic methods such as HTMLElement.focus()), and false when the event was dispatched via EventTarget.dispatchEvent(). The only exception is the click event, which initializes the isTrusted property to false in user agents.

MDN Reference

NONE: 0
resultIndex: number

The resultIndex read-only property of the SpeechRecognitionEvent interface returns the lowest index value result in the SpeechRecognitionResultList "array" that has actually changed.

MDN Reference

results: SpeechRecognitionResultList

The results read-only property of the SpeechRecognitionEvent interface returns a SpeechRecognitionResultList object representing all the speech recognition results for the current session.

MDN Reference

returnValue: boolean

The Event property returnValue indicates whether the default action for this event has been prevented or not.

MDN Reference

srcElement: EventTarget | null

The deprecated Event.srcElement is an alias for the Event.target property. Use Event.target instead.

MDN Reference

target: EventTarget | null

The read-only target property of the Event interface is a reference to the object onto which the event was dispatched. It is different from Event.currentTarget when the event handler is called during the bubbling or capturing phase of the event.

MDN Reference

timeStamp: number

The timeStamp read-only property of the Event interface returns the time (in milliseconds) at which the event was created.

MDN Reference

type: string

The type read-only property of the Event interface returns a string containing the event's type. It is set when the event is constructed and is the name commonly used to refer to the specific event, such as click, load, or error.

MDN Reference

  • The composedPath() method of the Event interface returns the event's path which is an array of the objects on which listeners will be invoked. This does not include nodes in shadow trees if the shadow root was created with its ShadowRoot.mode closed.

    MDN Reference

    Returns EventTarget[]

  • The Event.initEvent() method is used to initialize the value of an event created using Document.createEvent().

    Parameters

    • type: string
    • Optionalbubbles: boolean
    • Optionalcancelable: boolean

    Returns void

    MDN Reference

  • The preventDefault() method of the Event interface tells the user agent that the event is being explicitly handled, so its default action, such as page scrolling, link navigation, or pasting text, should not be taken.

    MDN Reference

    Returns void

  • The stopImmediatePropagation() method of the Event interface prevents other listeners of the same event from being called.

    MDN Reference

    Returns void

  • The stopPropagation() method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases. It does not, however, prevent any default behaviors from occurring; for instance, clicks on links are still processed. If you want to stop those behaviors, see the preventDefault() method. It also does not prevent propagation to other event-handlers of the current element. If you want to stop those, see stopImmediatePropagation().

    MDN Reference

    Returns void
