It works very intermittently for me (Chrome on Windows, with plenty of RAM and CPU). When I click the "speak" button, it makes a network request (as shown in the Chrome devtools) and immediately gets back a response that looks big enough to be an audio blob. But most of the time, instead of actually playing the audio, it just sits there with a spinner for anywhere between 30 seconds and 5 minutes before giving up, with no errors in the console.
