Resources for studying Mandarin assimilation, connected speech, and elision

[歐博思]

I was wondering are there any good resources for studying patterns of assimilation, connected speech, elision, etc? Such as how the Wikipedia article on Beijing-nese mentions the j/q/x ->y and zhi/chi/shi ->r phenomenon.

San Duanmu's 'The Phonology of Standard Chinese' has a section on consonant reduction, vowel devoicing, syllable mergers etc. You can also look at 曹文's 汉语语音教程 for a more detailed account of sound change in connected speech.
