To Reproduce
Steps to reproduce the behavior:

1. clone repository and cdinto it
2. create/increase swap to 1GB (for scipy build)
3. sudo mycroft-pip install .
4. configure "hotword" in mycroft.conf
5. reboot/restart Mycroft and look into voice.log

Environment (please complete the following information):

• Device type: Mark 1
• OS: Raspbian/Debian Jessie
• Mycroft-core version: 21.2.1

Thanks for giving it a go Dominik. I hadn't tried it on a Mark 1 at all.

It's not something that I think we'll have time to prioritize, but interested if someone does find a fix.

Upgrading GLIBCXX (by installing libstdc++.so from Debian Stretch distro) leads to next error - GLIBC version does not match.
As GLIBC is deeply linked into system I do not see a chance to get this running on Mark-I / Debian Jessie.
