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.
Vowels form one of the two principal classes of speech sound, the other being that of consonants. Vowels vary in quality, in loudness and also in quantity (length). They are usually voiced, and are closely involved in prosodic variation such as tone, intonation and stress. Vowel sounds are produced with an open vocal tract. The word vowel comes from the Latin word vocalis, meaning vocal (i.e. relating to the voice). In English, the word vowel is commonly used to refer both to vowel sounds and to the written symbols that represent them.
