Gcast, a podcast service used by quite a few teachers for having their students record by phone, has announced they’re starting to charge for that feature (thanks to Ann Shelley, an ESL Community College teacher here in California for the tip). The cost will be $99 per year.
Gcast won’t charge for uploading audio files from your computer. However, if you’re going to have students record with a computer mike, I think there are a lot better and easier options on my The Best Sites To Practice Speaking English list.
There used to be several web tools that let you record by phone for free but, as far as I can tell, they all charge for that feature now. Does anybody know of a site that still lets you do it without charging?
