It is known that English has a set of aspirated consonants, the allophones [pʰ], [tʰ] and [kʰ] of /p/, /t/, /k/, respectively. Are there other consonants with aspirated allophones? In which cases do them occour?
I am asking it because /d/ in the beginning of words like "dance" or "doctor", I hear what looks like a small aspiration almost like [dʰ] or even a very subtle [d͡z], the difference is really clear if you compare with the /d/ in italian "dottore" or portuguese "doutor", where it sounds lika a plain [d]. I am a Portuguese native speaker and it really sounds like a different phone to me and I could not find any answer to this question.
