Error

There is an error when downloading the tiny model for Spanish. It will not let me download it (Download failed: HTTP 404 for encoder_model.ort)

Also, when choosing the default language I want to translate from (i.e., Español), when I close and reopen the app, my preferences for that language are not saved. Also, it doesn’t seem to pick up any Spanish being spoken. If I use the default language (Japanese, I think), it does detect audio of the speaker speaking. But since they aren’t speaking Japanese, it’s not useful.

Even though no words in the audio are being detected, I don’t see a location where I can see the saved recordings either. It isn’t under “saved transcripts”, unless that is only for when words are detected.

When clicking “start”, the 0:00 on the right never increases. I’m not sure the cause.

The green bar indicating it is detecting sound, it will show words, but only on the default language. And I have to click “TV Mode” first and then exit
