In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract. In English language there are 24 consonant sounds. In phonology class I learned the exactly pronunciation of each of them, through a chart, when I could see the place and the manner of articulation of every sound. It was very useful for me, because now I can identify the consonant sound when I heard a word, so I can recognize what it means. To learn English is indispensable know the correct way to pronunciation the words, and the consonant sounds is the 80% of the total articulation of them, so, if you recognize all of these sounds, can be said that you almost know how speak this language.
