Hi,
i found the implementation of PicoTTS not working for the dockerized setup. It would be a really nice addition in order to facilitate an offline setup.
I had success running the command “apk add --no-cache picotts --repository=http://dl-cdn.alpinelinux.org/alpine/edge/testing && apk add --no-cache sox --repository=http://dl-cdn.alpinelinux.org/alpine/edge/testing” in the container, however this is not a permanent solution as it would be gone the next time the container updates…
