The unvoiced French consonant sounds are CH, F, K, P, S, and T. All unvoiced consonants have a voiced equivalent; i.e., the pairs are pronounced in the same place in the mouth/throat but the first is unvoiced while the second is voiced: CH - J. F - V. K - G.
These two groups are known as vowels and consonants. A vowel is a speech sound produced by comparatively open configuration of the vocal tract, with the vibration of the vocal cords but without audible friction. A consonant is a basic speech sound in which the breath is at least partly obstructed. Therefore, the main difference between vowels and consonants lies in their articulation; a vowel is articulated with an open vocal tract whereas a consonant is articulated with complete or partial closure of the vocal tract.
