speechSynthesis API example gives error

Question

The example given on Web Speech API Specification

    speechSynthesis.speak(SpeechSynthesisUtterance('Hello World'));

gives the following error on chrome:

Uncaught TypeError: DOM object constructor cannot be called as a function.

Can anyone help here?

Thanks!

Answer 1

I think there is a type in the specifications and you are expected to use the new keyword with the SpeechSynthesisUtterance object. Try this:

speechSynthesis.speak(new SpeechSynthesisUtterance('Hello World'));
