^ abcdefghGujarati contrasts dental [t] and [d] with retroflex [ʈ] and [ɖ] (as well as aspirated variants). Both sets sound like /t/ and /d/ to most English speakers although the dental [t] and [d] are used in place of the English /θ/ and /ð/ (with [ð] occuring as a spirant allophone of [dʱ] in Gujarati) for some speakers with th-stopping.
^ abcThe voiced retroflex stops and the nasal /ɖʱ,ɖ,ɳ/ have flapped allophones [ɽʱ,ɽ,ɽ̃]. Intervocalically all three are flapped. The stops are also flapped when before or after other consonants.Mistry (1997:659) The stops are unflapped initially, geminated, and postnasally; and flapped intervocalically, finally, and before or after other consonants.Masica (1991:97).
^ abcWhile there is dialectal variation in this regard, for Wikipedia transcriptions [ʃ] appears contiguous with palatal segments and [ʂ] appears before retroflex consonants: [spəʂʈ] (‘clear’).Mistry (1997:658)
