@cmurrayis This is caused by not entering the environment variable correctly or not entering them at all... Check you entered environment variables correctly in your docker run command

DEFAULT_SPEED=1 -e DEFAULT_LANGUAGE=EN -e DEFAULT_SPEAKER_ID=EN-Default

Ah cheers - Should wake up a little more before trying things!
