Prerecorded voices would require limited phrases. This assumption doesn't hold for routing engines adding street names into the instructions. Also supporting multiple routing engines doesn't help either ...

In theory, its possible. I don't know whether Valhalla imports multiple names (if available) when making the tiles. As soon as the names are available, should be possible to tag them in the instructions. Its not done yet, as far as I know.

I haven't filed the issue describing it in Valhalla's repo since I am not sure we can actually make use of this output (yet?). I think I saw somewhere mimic/flite issue regarding reading multi-language text, but it wasn't resolved at that time. Which brings the question up regarding partitioning: is it modRana/Poor Maps/... who is supposed to split the sentence and later glue it together or TTS? I would expect TTS to do that, but maybe its naïve.
