web speech api - speech synthesis .lang property not working

问题

im trying to use web speech api to transcript a word in Portuguese, i set the property to 'pt-BR' ( unfortunately Portuguese - european is not supported) but, always replies in english.

Can someone help?

Thanks

code:

        <script type="text/javascript"> 
            var synth = window.speechSynthesis;
            function falatarea(){
                var utteranceY = new SpeechSynthesisUtterance();
                    utteranceY.text = "teste";
                    utteranceY.lang = "pt-BR";
                    utteranceY.voice = "pt-BR";
                    window.speechSynthesis.speak(utteranceY);
                    }
        </script>

Seems like Chrome broke recently. I had code working, now its not.

As a work-around, you can set the .voice

voices = window.speechSynthesis.getVoices()

var utterance = new SpeechSynthesisUtterance("lo que practico");

utterance.voice = voices[3];
utterance.lang = voices[3].lang;

window.speechSynthesis.speak(utterance);

Perhaps the API changed as before when a female/male voice were both available it was not possible to pick one in particular. I still set lang for other browsers (or older chromes).
