In an earlier post I described how to install deepspeech on a Raspberry Pi 4. That wasn’t exactly a really smooth install, but I managed in the end.

Upgrading to deepspeech 0.7 is much easier:

Activate the virtual environment:

source dev/deepspeech-train-venv/bin/activate

Upgrade deepspeech

pip install --upgrade deepspeech
