You probably mean "e.g." as "for example", not "i.e."?

This might be on purpose and part of the training data because "for example" just sounds much better than "e.g.". Presumably for most purposes, linguistic naturalness is more important than fidelity.

Sometimes I use “for example” and “e.g.” in consecutive sentences to not sound repetitive, or possibly even within the same sentence (e.g. in parentheses). In that case, speaking both as “for example” would degrade it linguistically.

In any case, I’d like TTS to not take that kind of artistic freedom.

I did mean "i.e." That's why it is a problem : - \
