Unable to create audio on Raspberry Pi3

[BongoEADGC6]

I've tried quite a few times to create voices with Mimic on my rPi3.

I'm able to run ./bin/mimic -t "Hello. Doctor. Name. Continue. Yesterday. Tomorrow." -o hello.wav
but when i run aplay hello.wav I hear no audio, but any other wav file plays just fine.

I installed this with mycroft-core using ./dev_setup.sh

[BongoEADGC6]

./bin/mimic -t "Hello. Doctor. Name. Continue. Yesterday. Tomorrow." -o /tmp/hello.wav -v
times faster than real-time: 2.618549
(4.479819 seconds of speech synthesized in 1.710802)

aplay /tmp/hello.wav
Playing WAVE '/tmp/hello.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

Does sound output work?
./bin/mimic -t "Hello. Doctor. Name. Continue. Yesterday. Tomorrow."

Mycroft's configuration should use the alsa backend if I'm not mistaken.

Edit: I'll start building mimic on my rPi and test it out later tonight.

In order to find out what is going on, try specifying the voice name as well, just to make sure we are explicit about it:

./bin/mimic -voice ap -t "Hello. Doctor. Name. Continue. Yesterday. Tomorrow."

Update: Fix the command, as @forslund wrote it right.

[forslund]

I think the voice name is shorter, just ap (but I might recall incorrectly):

./bin/mimic -voice ap -t "Hello. Doctor. Name. Continue. Yesterday. Tomorrow."

or the path to the voice file

./bin/mimic -voice ./voices/mycroft_voice_4.0.flitevox -t "Hello. Doctor. Name. Continue. Yesterday. Tomorrow."

I get no sound at all. I've even exported it to a windows machine to play through VLC. No luck on that either.

This was after i upgraded to a new version. Everything was working previously.

What version does Picroft report? It scrolls by during the bootup, surrounded by =====. Are you at 0.8.6?

Oh wait, I just read above. Are you not using a Picroft install? Just using the dev setup from Github method?

[BongoEADGC6]

That's correct, Mr. Penrod.

I've since tried to install using the apt package and that worked. I'd like to avoid that however since the apt package method does not include the ability to use virtualenv to install python modules. (EDIT: sudo pip seems to work for this actually. Didn't think of that before.)

I've remove the mycroft-core folder and started again, but that did not work either.
So something may be broken in the dev_setup.sh from an already existent install.

Can you upload the wav somewhere so I can take a look at it.

also it would be interesting to see if the unittest passes. Try running make check.

Got the same issue after a fresh compilation on a pi 0: slt, rms voices works, ap outputs nothing.
It does work when I use  -voice "voices/mycroft_voice_4.0.flitevox" which I believe is "ap".

[forslund]

Thanks @trqx, yes ap is the precompiled version of voices/mycroft_voice_4.0.flitevox. That narrows it down somewhat.

Managed to reproduce and starting to bisect the issue

[forslund]

Seems to be 3cad70a that introduces this behaviour.

[BongoEADGC6]

@forslund Where would be preferable to upload the audio file?

I've added it here

[forslund]

@BongoEADGC6 since I've managed to get my rPi up and running there is no need to upload it. I've reproduced the issue and am investigating.
