so i'm going back to a former project of mine: getting Achernar to work with piper. it will use en-us-chirp3-hd-achernar. my original plan was to use Gemini Achernar, problem being Gemini is very unpredictable and can generate very varying results, you will not get the same voice without trying like a bunch of different times, so it's google cloud Achernar. we'll see how far we can take this with colab from Google...
