Thank you so much for your advice! In fact I've always thought that the sounds "p", "t" and "c" were always aspirated, but now thanks to you I know that they aren't.<<
/p/, /t/, /k/, and /tS/ are normally aspirated word-initially and before stressed vowels in English dialects except in the aforementioned cases /sp/, /st/, /sk/, and /stS/ and elsewhere are unaspirated. There are some cases like some dialects aspirating word-final /p/, /t/, /k/, and /tS/ at times, but these cannot be applied to English in general.
