| 释义 | > as lemmasmid-front (a) Phonetics. Of a vowel sound: produced with (the highest part of the body of) the tongue at a relatively medium height in the mouth; showing auditory characteristics typical of sounds traditionally described as being so articulated; esp. in mid-back, mid-central, mid-front. Cf. high adj. 7, low adj. 6.Since the early 20th cent., the use of the terms high, mid, and low to designate vowel sounds has been associated with the system of cardinal vowels formulated by Daniel Jones, originally based on X-ray photographs of the interior of the mouth, in which both mid-high and mid-low front and back vowels are distinguished. However, many phoneticians now consider the most important factor to be the position of the major constriction formed by the tongue, of which tongue height is simply an approximate and not invariably reliable indication. The method of classification with reference to tongue height continues to be the one most widely employed, since it is a convenient means of categorizing auditory perceptions of vowel sounds.

M. Bell Visible Speech: Sci. Universal Alphabetics 72 The ‘Definers’ stand at the upper end of the stem for the ‘high’ vowel of each class; at the lower end for the ‘low’; and at both ends for the ‘mid’ vowel of each series. 1874 H. Sweet in Trans. Philol. Soc. 533 The short vowels do not seem to have changed much in the last few generations. The most noticeable fact is the loss of æ among the vulgar. It is modified by raising the tongue into the mid-front-wide, resulting in the familiar ceb for cæb. 1908 H.
