Dammit, you cheated though! Why must you always do that? In your sentences it doesn't matter what your emotional state is, it makes no difference; bit like life really.
Hopefully, you can see that at least my chosen sentences have an emotional aspect?
An LLM could add emotional values to my previous sentences that a TTS can use for tonal variation, for example.
I can read your example in three different tonalities, of which one is the likeliest. Depending on our relationship, the interpretation could differ.
The point is, the OP suggested that emotions are just a feature of language. I argue that text is one of the worst transmission channels for emotion. But I don't argue that it's not possible at all to do so, if you suggest that. That would be just silly.
Makes me wonder: are there Unicode code points for tone of voice? If not could there be?
