The emma read-only property of the SpeechRecognitionEvent interface returns an Extensible MultiModal Annotation markup language (EMMA) — XML — representation of the result.

Note: EMMA is defined in the specification EMMA: Extensible MultiModal Annotation markup language. You can see muliple EMMA examples in the spec.

Syntax

var myEmma = event.emma;

Value

A valid XML document. The exact contents can vary across user agents and recognition engines, but all supporting implementations will expose a valid XML document complete with an EMMA namespace. If the speech recognition system does not supply EMMA data then the user agent will return null.

Examples

recognition.onresult = function(event) {
  var color = event.results[0][0].transcript;
  diagnostic.textContent = 'Result received: ' + color + '.';
  bg.style.backgroundColor = color;
  console.log(event.emma);
}
