I'm also a deaf person who is a bit disappointed about there not being any transcripts because I love the repro man blog, and I'm always sharing stuff from it with people who i think will enjoy it. I took Pantone Blues with me on holiday to the Derby Dales when you published it and I sat alone in my cycling gear in loads of nice rural pubs over many a pint of guinness, cackling joyfully to myself at it. I also fucking love Forteana (I subscribe to ALL the zines and journals) and Kraken Cove sounds right up my alley.
However! I have a suggestion! If you were to use something like this during the recording sessions: https://webcaptioner.com/captioner then it would automatically produce a transcript for you that you could save and add to Podbean along with the audio. Here's an example of a Government Digital Service podcast with a transcript added so you can see what that looks like.
Automatic captions aren't great, and you'll probably have to make corrections. People on this thread have led me to believe you and Fucking Amazing Dave have strong accents and maybe it'll be shit at working out what you're saying. But it's worth a try, right? Google docs have "voice typing" in them too. Or there's Otter.ai, which is free if your shows are less than 40 mins each and under 600 mins a month. There's options! And I'd love to be able to follow both series.
