A definite and very frequent process of assimilation is
observed when [s], [z] sounds are followed by the palatal [j] in the
unstressed part of the phrase. The alveolars tend to become
palato-alveolar in informal conversational style.

The palatal [j] is strong enough to affect the manner of
articulation of the preceding [t], [d] sounds. In accordance with
the tempo and style of speech, individual fluency, number of
recipients and other situational factors the assimilated segment
preceding [j] may consist of several sections with gradually
changing features. The process most often leads to an affricate:
would you [wudju: wud'ju wuʤu]
could you [kudju: kudtju kuʤu]
mind you [maindju: maindtju mainʤu]
can't you [ka:ntju: ka:nt∫ju ka:nt∫u]
about you [əbautju: əbaut∫ju əbаut∫u]
The elision of consonants is no less frequent process in
informal speech than a vowel elision. The most common
consonants involved in elision are [t] and [d]. Elision usually
occurs in a syllable final sequence when the sound stands between
two consonants. It is said to be more common for [t] and [d] to be
elided between the other two consonants than it is for them to be
pronounced.
