Human.speak doesn't in Ubuntu, and job hangs.

[JamesNewton]

This sample job (from the help panel)

new Job({name: "j1",
         do_list: [
           Human.speak({speak_data: "hi there folks",
                        rate: 0.25,
                        wait: true}),
           IO.out("done")
         ]})

in Ubuntu 18.04, DDE 3.8.7,

1. Doesn't produce any sound
2. Causes the job to hang.
   I tried to debug it, but found the code confusing. It seems to execute the speech requirement, and then get suck in instruction.js in a jqx library?

It doesn't appear that DDE installs a text-to-speech package, and instead uses espeak on the robot and some native call otherwise? Perhaps I missed it in Package.json?

There dont' seem to be good alternatives which don't require the installation of other packages.
https://www.npmjs.com/search?ranking=optimal&q=text-to-speech

but the key is that if it doesn't work, it shouldn't lockup the job.

DDE uses SpeechSynthesisUtterance https://developer.mozilla.org/en-US/docs/Web/API/SpeechSynthesisUtterance which is part of Web Speech API It works on Mac in Chrome in both DDE3 and DDE4 (browser based). From https://askubuntu.com/questions/761975/chromium-is-not-generating-voice we see that Ubuntu/linux is deficient, but some pundits claim that overall the implementation is poor for many configurations. https://dev.to/jankapunkt/cross-browser-speech-synthesis-the-hard-way-and-the-easy-way-353 claims to have a solution. Let's give this a try on your linux system and see if we can get it to work. I'm a bit reluctant to not use the web api standard, but if I can see where its erroring, quite possibly when calling: var msg = new SpeechSynthesisUtterance(); or var voices = window.speechSynthesis.getVoices(); or speechSynthesis.speak(msg) If I wrap the offending call in a try catch, then, if it errors, we can catch it, then call the EasySpeech pkg from the above URL. Let's do this in our next call.
