Other Comments

Yes, it's finally here! I reached out to the developer to request several new features like progress bars to indicate ongoing downloads and a voice manager, the ability to download and use multiple voices at once, and better handling of non-English characters. Leave positive reviews and 5 stars to support the developer. He is quite receptive to user feedback and wants to keep the app free.

I'll be giving this one a go.

I love the fact that these voices are now available on my iphone! There is no lagging between swiping and verbalization, there is no excess battery drainage that I can see, and this is just a wonderful app! Five Stars!

I’m not sure what’s going on. I’ve done everything I can within the screen that comes up after tapping the Help button. I don’t see it at all in my voiceover settings even after I have installed the Voice model. Is there anything I’m doing wrong?

Not something I'll personally use. I'm glad there is more choice for those that want it. An awesome job to the dev for bringing it to the iPhone.

I may try it out just to see what it is like. but I'll mostly stay with eloquence.

Make it so that one can play a sample without downloading and installing the voices? That would make it easier to preview and decide if one likes it or not before commiting to download and installing then beeing able to hear a sample.

so, if i install a voice, download, and install a 2nd the first voice not then available? and yes samples need to be available why i wonder are all the voices not offered as high quality?

seems good choice though of voices.

I have previously trained several piper tts voices on my computer with use with NVDA and Orca, but I am not sure what format they want the voices in to add to the app. First I tried uploading the onnx and onnx.json files seperatly, which did not work. Then I tried the NVDA way of a tar.gz with both files and the model card, then zip, then I tried tar, with no success. What am I supposed to do to get this working?

I installed the german Karlson voice. Then I installed something else cause I didn't like it. But no matter what voice or language I install it doesn't work, every voice is german karlson. Tried reinstalling the app and then no voice made any sound till I downloaded karlson again. And now I again only have karlson.
