How to setup Kalliope, a voice-controlled personal assistant, if you don't run an officially supported distro like Debian |
Hello again,
It's been some time I wanted to try out a personal vocal assistant that is 100% free software, in working condition and simple to customize. Unfortunately there aren't that many that satisfy all the those conditions.
There is however an interesting project called Kalliope which apparently has all the requirements I was looking for (we are very close anyway :) ) Here's a video posted by one of the authors
Introduction
There are a few aspects of Kalliope that I've grasped in a few hours of usage and that I would like to share. First of all basic configuration is done through YAML files, where you need to describe expected input and outputs for each case. Inputs are vocal commands, while outputs can be a composition of voice, shell scripts or ad-hoc python scripts. You will find examples once you install a specific language "starter".
According to the official documentation there are just a handful of supported GNU/Linux distros. Unfortunately no Arch Linux derivative (including Parabola) is among them. Infact, after trying both the manual installation and an AUR package and given the results I decided to switch to one of the officially supported distros: Debian (at least for the moment).
Alternative installation
Now, since I don't have any working installation of Debian 8 (Jessie) I attempted to run it inside QEMU. To do this I used my qvm script I made some while ago. Once I had Debian up and running I tried the microphone test. It turned out that I didn't have any soundcards available in the virtual machine. A couple of options added in the qvm script did the trick. Now I could record and listen to my voice through QEMU.
If you are on Parabola or Arch Linux please make sure to install qemu
instead of qemu-headless otherwise the audio would be unusable. Apparently
the ALSA audio driver is not included in the qemu-headless package. See $ qemu-system-x86_64 -audio-help for more information.
According to the
official documentation,
with Debian 8, the contrib and
non-free repositories should be enabled before installing all the
dependencies. Fortunately, only one of them is non
free:
libttspico-utils. I simply removed that from the installation command and
left the sources.list file as-is:
# apt-get update
# apt-get dist-upgrade
# apt-get install git python-dev libsmpeg0 flac dialog libffi-dev libffi-dev libssl-dev portaudio19-dev build-essential libssl-dev libffi-dev sox libatlas3-base mplayer libav-tools
After that, I continued with the official
documentation.
I followed Method 1 - User install using the PIP package. Apparently
every other component is free software, but this still needs to be verified
thoroughly. Because I removed libttspico-utils, which is an offline text to
speech engine, I had to use another one. All of them except espeak are
online TTS. Here
you will find the installation instructions for espeak. The speech to text
system used is Google's one because, although cloud-based, it's much more
precise than the offline STT at the moment.
Finally I downloaded the english starter version and tested it out. Everything worked.

SSH
After testing all of this stuff, using the -x option for qvm, I made
another "discovery", by running qvm with:
$ ./qvm -n
$ ./qvm -a
i.e: connecting via SSH only. Apparently this also has the ability to route the audio. If you put this into the account, including one of the [previous posts]({{ site.baseurl }}/notes/qemu-ssh-tunnel.html), maybe in some way you could have one instance of Kalliope running in QEMU with an unlimited (!?) number of remote IO audio devices...
Cheers!
