Given that the FSF considers Apache-2.0 to be compatible with GPL-3.0 [0], how could the fact that phonemizer is GPL-3.0 possibly be an issue?

Compatible means they can be linked together, BUT the result is GPL-3.

The result can only be distributed under the terms of the GPL-3. That's actually a crucial difference: there's nothing preventing Kitten TTS from being Apache licensed, soliciting technical contributions under that license, and parts of its code being re-used in other software under that license. Yes, for the time being, this limits what you can do with Kitten TTS if you want to use the software as a whole (e.g. by embedding it into your product), but the license itself is still Apache and that can have value.
