I just noticed that when enabled in the language learning options:
Books in chinese language (such as the Kindle User's Guide Chinese Edition in these screenshots) will (unsurprisingly) display pinyin above chinese characters:
And have an active pinyin
level menu:
The feature doesn't seem to be implemented in a way similar to wordwise. I couldn't find an equivalent of the
mnt_us/system/kll/kll.en.en.klld wordwise data base with accompanying
mnt_us/bookASIN.sdr/LanguageLayer.en.ASIN.kll in the sdr directory for the book.
By curiosity, has anybody researched how/where pinyin is implemented?
