User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:92.0) Gecko/20100101
Firefox/92.0

Steps to reproduce:

Using the firefox snap, open the devtools console, and enter:

    speechSynthesis.speak(new SpeechSynthesisUtterance("Testing 1 2
3"));

Actual results:

Nothing (no text is being spoken).

Expected results:

speech-dispatcher should be speaking "Testing 1 2 3".

This is a snap-specific issue, speech synthesis works well with an
unconfined build of firefox. More details at

The [Bugbug](https://github.com/mozilla/bugbug/) bot thinks this bug
should belong to the 'Core::Web Speech' component, and is moving the bug
to that component. Please revert this change in case you think the bot
is wrong.

I can confirm it doesn't work for me, neither in the snap nor in the
upstream tarball.

For the snap, [this thread](https://forum.snapcraft.io/t/text-to-speech-

After bug 1666703 is fixed, there are still a few roadblocks:
 - we need to add `libspeechd2` as a `stage-packages` component in the firefox snap
 - we need to `prime` `usr/lib/*/libspeechd.so.*`

That is still not enough. By default, communication is done over a
socket `$XDG_RUNTIME_DIR/speech-dispatcher/speechd.sock`, granting this
would need some snapd interface change.

Experimenting further by forcing `SPEECHD_ADDRESS=inet_socket` (as well
as in the configuration file `/etc/speech-dispatcher/speechd.conf`, one
still cannot get `speechSynthesis.getVoices()` to return more than an
empty array. It looks like `libspeechd2` somehow handles some auto
spawning of the daemon, and I assume this is getting blocked by the
Snap-level sandboxing.

This can be bypassed by issuing `spd-say -L` aside of a running Firefox,
and once you have a process spawn quickly isssuing a
`speechSynthesis.getVoices()` to connect to it. Once that is done,
Speech Synthesis can work.

Auto spawning seems to simply require the executable to be within the
Snap. Ubuntu people suggested we rather rely on socket activation as
reported on https://github.com/brailcom/speechd/issues/448. That, in
combination with bug 1787245 should be enough.
