This is an annoying quirk of English language, but most of TTSs (including Edge) pronounce longer "shhhh" like /ˈɛs ˈeɪtʃ ˈeɪtʃˈeɪtʃ/. This could be demonstrated with simple:
edge-playback -t '"Hey, shhhhh", she whispered.'
Only shh is pronounced correctly (whatever that means). So I suppose that in the book pre-processing (of course, with an optional switch on, like --shhh) all shh+[^a-gi-z] could be replaced with shh.
Just for record: I myself replace all shhh+s with shush in the exported text file, it is also read quite well by TTS.
