  • Phonetics - Stress, Intonation, Rhythm | Britannica
    Phonetics - Stress, Intonation, Rhythm: Vowels and consonants can be considered to be the segments of which speech is composed Together they form syllables, which in turn make up utterances Superimposed on the syllables there are other features that are known as suprasegmentals These include variations in stress (accent) and pitch (tone and intonation) Variations in length are also usually

    Phonetics - Vowel Sounds, Articulation, Acoustics: Vowels traditionally have been specified in terms of the position of the highest point of the tongue and the position of the lips Figure 2 shows these positions for eight different vowels The highest point of the tongue is in the front of the mouth for the vowels in heed, hid, head, and had Accordingly, these vowels are classified as front
