Clock does not speak in olpc build 12.1.0

[manuq]

After toggling Talking clock, I can't hear the speak. Log attached.

FWIW: Clock expects the builds espeak to work, you should be able to go to the terminal and type...

espeak hello world

...and have it speak to you, build 12.1.0 fails with an "wave_pulse.cpp: Assertion 'stream' failed." (11.3.1 and most past builds work OK). Happy to move to streamer-espeak if this is an elegant way to avoid an ever occurring bug in espeak, though it's a shame if espeak from the terminal can't be used as shipped.

I have the same problem in XO 1.75 os8. Same happens in XO 1.5 os8

The speak functionality should be ported to the gst python API. The global text to speech implementation can be a good reference, sugar/src/jarabe/model/speech.py .

Fixed in Clock-8. Now defaults to gstreamer espeak plugin, with a fallback mode to the espeak command for older Sugar builds. However note that there seems to be an activity translation build issue in 12.1.0 so the only time text spoken is the default "What Time Is It" (this happens when translations are not found). The translations work fine in 11.x.x and an very early 802 build, but not in 12.1.0 build 8 (please re-test if you can!).

Confirmed this bug in OS9, Clock8, says "What Time Is It"

The i18n has been changed.

"What Time is It" used to be msgctxt, now i tis the msgid itself.

See several similar changes that caused the POT to be different. These need to be fixed in the code t ogettext picks up the real strings.

Can't say for sure this will solve it, but if the msgid is "What time is it", that is all that will get translated.

For reference, Pootle's local copy of the POT was pushed back to Gitorious in December:

​http://git.sugarlabs.org/clock/mainline/commit/30726bdba87892aa4a7a6e81dee2f199d0153e49

but the code changes that the potupdater script would have picked up happened earlier. Judging from the revised POT creation date in Nov, I guess.

Ariel and me, found that there is a gst issue..

452 try:
453 pipe = gst.parse_launch(pipeline)
454 bus = pipe.get_bus()
455 bus.add_signal_watch()
456 bus.connect('message', gstmessage_cb, pipe)
457 pipe.set_state(gst.STATE_PLAYING)

commenting this code seems to fix the problem, but the code needs to be changed, as we saw it gst is being run inside a thread to use espeak, and this call to espeak in the thread doesn't have all the needed configuration for espeak that is in speaker.py.

I separated the POT issue in a new ticket: #3668

[garycmartin]

Fixed (speaks, and uses the correct spoken accent and other voice settings) in Clock-9 release.
