Minor bugs

[henningzakrisson]

Hi! I found this by accident and have tried it out for my TTRPG campaign - great work! I however had to edit quite a bit of code to get it to run locally on my Macbook Air M1. Here are some examples:

Here, I get an error because it is trying to run `.strip()` on `None`. So I guess the key exists in the config, but it isn't filled in, causing the default value 'ogg' not to be used. For me this created a file path that is double - the `audio_file` is already the full path so the join is not required.

I also had to manually change
cuda to cpu in the recognize input because even if I say y to the prompt in the beginning, it will try to run it over cuda and fail.

Figured you might be interested in hearing this so I wanted to share. Thanks once again for the package!
