In Taiwanese phonetics, aspiration is the strong burst of breath that accompanies the release of obstruents. The aspirated consonants are ph, th, kh, ch, zh (IPA: [pʰ], [tʰ], [kʰ], [tɕʰ], [tsʰ]). They are composed of the symbols for the plain, unvoiced, unaspirated consonant (see tenuis consonant), followed by the letter h for aspiration.
You may have already noticed that this is a bit different from English, which always aspirates p, t, and k when they occur at the beginning of words.
