This is an outdated fork of https://github.com/jasperproject/jasper-client.

With these patches it is possible to use Jasper with different languages.
Only the Time, Unclear, Joke (partial) and Life plugins are translated yet.

I wanted to use Jasper in German, so I did the following on my Arch Linux laptop:
- Set up Jasper
- Make sure everything works in English. I needed to change `aplay -D hw:1,0 str(filename)` to `aplay str(filename)` in client/stt.py
- Get the language model, I got mine from [here](http://goofy.zamia.org/voxforge/de/).
- In my case, the fst was in `phonetisaurus/dict-xsampa.fst` and the hmm_dir was `voxforge-de-r20141117/model_parameters/voxforge.cd_cont_3000`. After some fiddeling I realized that there are different formats, `ARPA` and `XSAMPA`. pocketsphinx needs `ARPA`, but my model was `XSAMPA` - luckily there [is a script](https://github.com/gooofy/voxforge) to convert inbetween them. I changed a regular expression, added an option for the conversion and included this script. You need to add the line `fst_ist_xsampa: true` below the line with `fst_model` in your `profile.yml`.
- Now the keywords need to be changed. gettext does this, I added a draft translation. To convert it, go to Jasper's root folder and execute `msgfmt messages.po`. The phonetized words seem to be cached in `~/.jasper/vocabularies`, so you should flush it with `rm -rf ~/.jasper/vocabularies`.
- Next, configure espeak to speak in the right language, that is `voice: 'german'` in the profile.yml.
- I did not really like the espeak voice so I wanted to try PicoTTS instead. It turns out that the Pkgbuild is not working anymore because the source repository has been taken down (DMCA). [PicoPi](https://github.com/DougGore/picopi) worked fine for me:
  - Download, compile, install
  - Change `pico/tts/main.cpp` and replace the path `ttsEngine->init(synth_done, '../lang')` to the absolute path to the `lang` directory, because otherwise you need to be in the `tts` directory when running `./testtts`.
  - Compile again and add PicoPiTTS to `client/tts.py`. [Here](https://gist.github.com/MakeMeASandwich/cb284bae65f8b7870942) is a gist, it's hacky and insecure but works.
