Unable to create audio on Raspberry Pi3 about mimic1

[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."

[aatchison]

I'm working on building and testing on my pi.

[forslund]

Yes, should be fixed. Closing.

[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

[forslund]

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.

[zeehio]

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.

[BongoEADGC6]

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

[BongoEADGC6]

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

[penrods]

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.

[forslund]

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.

[forslund]

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.

[zeehio]

Sorry for giving you trouble... I bet there is a const correctness issue. I maybe added a const where I should have not and then that const tells the compiler to optimize something.

[forslund]

@zeehio no need to apologize. The work in cleaning up the build system was huge and one or two bugs are to be expected =)

It's not easy to check all platforms for issues, since this has only cropped up on raspberry Pi it may be some quirk with gcc for that architecture as well.

[forslund]

@BongoEADGC6, @trqx can any of you try the branch rpi-ap-voice-fix. To verify that what worked for me actually works for others as well. I still have to figure out the correct way to remove the warnings.

@forslund
I guess git clone https://github.com/MycroftAI/mimic.git -b rpi-voice-ap-fix --depth=1 get only what I need right? Compilation will take a bit of time ony a zero tho.

@forslund I can confirm, warnings are back and ap voice works with this branch on armv6h.

[forslund]

Thanks for testing @trqx, tonight I'll re-add the fixes for the warnings one by one and see which one breaks it and how to circumvent it.

[forslund]

I've pushed an update to the branch and it seems to be working and produces no warnings. I've tested on my Raspberry Pi and on my desktop computer and both seem to work fine.

@BongoEADGC6 or @trqx could one of you verify this before we merge?

[aatchison]

Ok, so I've finally built Mimic twice on the pi. Both the release branch and #100 give me just a pop.
Here is the strace
http://pastebin.com/uXKhHvsu

[aatchison]

Interestingly enough, I can also not run mimic as sudo.
root@raspberrypi:/home/pi/mimic# ./mimic -t hello audio_open_alsa: failed to set hw parameters. Invalid argument.

strace:

[forslund]

Thanks for testing @aatchison. Did you do a complete build and install? It looks like you are running the system mimic not the locally compiled mimic? I'm guessing you're configuring with --enable-shared, is this correct?

I've been running my tests directly from the build directory and doing a basic configuration without any specific flags. I'm building a shared lib version now and will try to install it as well.

As for the root issue, I'm having no issues on vanilla Raspbian.

[BongoEADGC6]

I tried to clone and build the GitHub repo today. Seems to build cleanly but still getting static. Guessing I need to reimage my SD to a clean raspbian image again.

I did two complete rebuilds of the #100 branch and for my raspberry Pi it's working ok.

No problem what so ever with the statically built mimic.

The one I built with --enable-shared and then installing it in the system had some trouble. To run the installed binary I had to help the sysem finding the mimic libraries using
export LD_LIBRARY_PATH=/usr/local/lib

If I didn't specifiy the path I got the following error message:

"mimic: error while loading shared libraries: libttsmimic_lang_all_langs.so.0: cannot open shared object file: No such file or directory"

Looking at @aatchison's strace dump it seem to find the file in the correct place (/usr/local/lib/). Can you try the file before it's installed, running ./mimic in the build dir?

[forslund]

For reference this is my procedure:

git clone https://github.com/MycroftAI/mimic.git -b rpi-voice-ap-fix --depth=1 mimic-rpi
cd mimic-rpi
./autogen.sh
mkdir build
cd build
../configure --enable-shared
make

Here I can test the executable before installing:

./mimic -voice ap -t "Hello there, you are looking well. would you like to see a tree house?"

Install on system:

sudo make install

Test system installation

export LD_LIBRARY_PATH=/usr/local/lib
mimic -voice ap -t "Hello there, you are looking well. would you like to see a tree house?"

I have tested this around five times now, Alan Pope speaking loud and clear. Doing the same for master will result in a low buzzing.

@aatchison do you think older mimic installations could be interfering somehow? If they were not uninstalled properly?

[BongoEADGC6]

@forslund I realized I was trying to clone the main repo, and not your branch. The steps you listed above worked perfectly fine for me.

[forslund]

@BongoEADGC6 Nice to hear. I'm still trying to figure out why this works and master doesn't but I'll probably push it as a quick fix during the weekend.

[forslund]

@BongoEADGC6 the branch has been merged, could you verify that master works for you and close this issue if you're happy.

[BongoEADGC6]

I tried to rebuilt from the mycroft-core and was still unable to.

[forslund]

I see mycroft core hasn't updated the mimic version number...I'll make a PR to update it tonight

[zeehio]

I believe this was fixed at MycroftAI/mycroft-core@4a498d9 . Am I right?
