--- Comment #9 from Simon Bates <sbates at ocadu.ca> ---
Hi,

I am experiencing this issue also. I can reproduce the issue with the following steps:

1. Open Safari Technology Preview 153 (additional OS details below)
2. Open the developer Console
3. Run the following: window.speechSynthesis.speak(new SpeechSynthesisUtterance("hello"))

Expected:

* To hear "hello" spoken

Actual:

* Nothing heard

When I run the JavaScript command above (window.speechSynthesis.speak(new SpeechSynthesisUtterance("hello"))) on Firefox and Chrome on the same computer, I hear "hello" being spoken.

I am able to get speech to work if I explicitly set the voice before sending the utterance to the speak method. If I run the following on the Safari Technology Preview 153, I am able to hear speech:

u = new SpeechSynthesisUtterance("hello");
u.voice = window.speechSynthesis.getVoices()[0];
window.speechSynthesis.speak(u);

Machine details:

* macOS 12.5.1
* Intel MacBook Pro
* I am in Canada (maybe there is a locale component to this?) and window.navigator.language is "en-CA" for me

Thanks very much for looking into this issue.

Regards,
Simon
