Returning to ANKI after a long layoff and it seems I can not add audio using Hypertts. I updated to the later version, that did not help. The error message I get says the API keys have expired. I have, I believe, gone through every Japanese voice available and nothing works.
It’s my understanding that hypertts is free, up to a certain limit, which I have not exceeded.
I’d love to resume studying but without that wonderful audio it would be of little value. If anyone could help, please do so.
