Aspirated consonant

In Taiwanese phonetics, aspiration is the strong burst of breath that accompanies either the release of obstruents. In MTL, aspirated consonants are written using the symbols for voiceless consonants (p, t, k, c, z) followed by the aspiration modifier letter h. The aspirated consonants are: ph, th, kh, ch, zh. POJ also uses h to denote aspiration. This is similar to how the International Phonetic Alphabet (IPA) writes aspirated consonants uses the aspiration modifier letter ⟨◌ʰ⟩ following symbols for voiceless consonants. French, Standard Dutch, and Spanish are some languages that do not have aspirated consonants.
