A hearing-impaired colleague thought transcripts would be quite useful: I have to agree. My wife is deaf in one ear--although she has it restored with a special hearing aid through the magic of a metal screw in her skull--and I had concerns about audio or video only publishing. Luckily, through colleague recommendations, I found CastingWords, a firm that charges a ridiculously small amount of money for complete transcriptions. I handed them a set of difficult, acronym-filled podcasts, and received fantastically good transcripts that require very little editing to fix a few misheard names and abbreviations.
I've posted the first transcript, from Podcast No. 13 with Steve Shaw of Kineto Wireless, as part of the extended entry for that podcast. In the future, I will plan to have transcriptions made immediately after posting, and have them available within a few days of the audio podcast.
I'll be posting transcripts over the next week or so from the other 14 podcasts broadcast to date.
