Speech synthesis processing is not shipped in Chromium source code.
Ordinarily, in order to use speech synthesis at Chromium a speech
synthesis engine needs to be installed, for example, espeak or espeak-
ng, and speech-dispatch needs to be installed
$ sudo apt install python3-speechd
then launch Chromium with
--enable-speech-dispatcher
flag.
However, no voices are loaded at snap version of Chromium at
Chromium 85.0.4183.102 (Official Build) snap (64-bit)

also has serious issues with Web Speech API implementation.
It should be possible to run
$ spd-conf
then edit the speech synthesis engine configuration file to modify
variations, which should be reflected in speechSynthesis.getVoices(),
however, that also does not currently work for non-snap Chromium, where
snap Chromium loads no voices at all.
Also, the queue to speech-dispatcher is severely broken at non-snap
Chromium, requiring executing speechSynthesis.cancel() to cycle through
the code that worked within the last few releases at
https://guest271314.github.io/SSMLParser/, where the code outputs the
expected result at Firefox 80 and Nightly 82.

Title:
Speech Synthesis Not Working
Status in chromium-browser package in Ubuntu:
Confirmed
Bug description:
In Ubuntu 16.04.5, Firefox supports Speech Synthesis by utilizing
Text-To-Speech voices provided by default from the operating system.
In Windows 10, both both Firefox and Chrome support Speech Synthesis
by utilizing Text-To-Speech voices provided by default from the
operating system.
However,in Chromium 68 and 69, although the API is supported, Chromium
cannot speak, because it doesn't seem to know how to load those Text-
To-Speech voices that Firefox is successfully utilizing.
Here's what users said at Ask Ubuntu, regarding the issue:

For example, this page should speak the text is shows:

The link above does not work in Chromium 69 on Ubuntu, however it does
work in the following browser/os combinations:
- Firefox (Ubuntu 16.04.5)
- Chrome (Windows 10)
- Firefox (Windows 10)
