Widget: Audio Add TTS Support to match Dashboard 1.0 Functionality

[kd9lsv]

Description

Discussed on #52.
@bartbutenaers pointed to create issue to not lose track.

Functionality was missing from #1506
Didn't include the Text to Speech functionality in new 2.0 node.

Pictures from Dashboard 1.0

No hurry on additional functionality.

Have you provided an initial effort estimate for this issue?

Thanks for doing the administrative work!

Reminder for myself: the frontend code for TTS in the old dashboard can be found here.

If I remember correctly, there was one issue with that implementation: you have a dropdown in the ui-audio's node config screen, that allows you to select which language needs to be spoken. But that "TTS voice" dropdown contains the languages available on the server running Node-RED, not the device running the frontend dashboard in the browser. So you can select a supported language in the config screen, but might not have speech in that language in your dashboard (if the client device doesn't support that particular language)...

Don't think we can solve that problem. But need to add it at least to the documentation.

Perhaps it is better to call it "preferred" TTS voice, to lower the expectations...

Since I developed the ui-audio node, you can assign this one to me (after Chistmas eve whenever you have more time).
