I see, TIL. Thanks for the explanation. I was thinking/imagining more along the lines of being able to drill down into phoneme pronunciation, adding micro-pauses to or pitch-bending certain syllables based on rules, for example, or having a firehose of machine readable annotations for a given utterance, including indications of the exact start and end times/samples of individual phonemes in the audio stream so you can then mix your own audio track that has additional augmentations in it into the final output, for example using your own synthesizer to modulate tones in the background representing the current indentation level. Yes, ridiculously complex; but by front-loading that complexity (and winning the data accessibility fights) it would be possible to do a lot of cool stuff... I understand some people swear by JAWS as the generally best-in-class solution, which has admittedly put me off NVDA as I feel I'd sort of absorb a sort of biased sense of what's possible or how audio output software works in general. I guess I should just install NVDA already since it's the realistic option - if I started testing stuff in JAWS and talking about it the only reasonable assumption people would be able to make was that I was using a copy that had drifted ashore from the high seas, which would be kind of true...
