The use of the library is four lines. Three set up the library (`phonemizer.backend.EspeakBackend(language="en-us", preserve_punctuation=True, with_stress=True)`), the other calls it (`phonemes_list = self.phonemizer.phonemize([text])`). Plus I guess the import statements. Even ignoring Google vs Oracle I don't think those lines by themselves meet any threshold of originality.

Obviously you can't run them (with the original library) without complying with the GPL. But I don't see why I couldn't independently of that also give you this text file under Apache 2.0 to do with as you want (which for the record still doesn't allow you to run them with the original library without complying with the GPL, but that'd be phoneme forcing you to do that, not this project)

You would have to be very specific about the dual-licensing to avoid confusion about what you are allowed to do under Apache conditions though. You can't just say "it's dual-licensed"
