high:

high [1]: pronounced with the body of the tongue raised up near the palate (the roof of the mouth). The term is used especially to describe vowels such as [i] ("ee") and [u] ("oo"). (See the diagrams of the principal organs of articulation and phonetic symbols for vowels.) Sometimes certain consonants, such as the palato-alveolar fricative "sh" [], are also considered high. Contrast low [1], mid [1]; see also close, open. [Spanish: alto [1]]

high [2]: with a pitch that is phonetically (or acoustically) high, that is, with relatively fast vibrations of the basic pitch of the voice. In this sense, one can say that in general the voices of women and children are higher than those of men. [Spanish: alto [2]]

high [3]: in a tonal language, the highest-frequency contrastive pitch. High tone is often written with an acute accent; e.g. á can mean 'a with high tone'. Contrast low [3] and mid [2] tone. [Spanish: alto [3]]
