| 释义 | approximant noun[ C ] phonetics specializeduk /əˈprɒk.sɪ.mənt/ us /əˈprɑːk.sə.mənt/ a consonant sound in which air is able to flow almost completely freely: 近塞流通音，无摩擦延续音，无擦通音 The sounds /w/, /l/, and /r/ are examples of approximants in English.在英语中，w、l 和 r 都是无摩擦延续音。 Linguistics: phonology & phonetics accommodation alliterative alveolar apheresis aphesis assonance diphthong homonym intrusive labial labialize labiodental lateral postconsonantal retroflex retroflexion rhotic rhyme unpronounceable unrepeatable Examples of approximantapproximant If the nasal vowel was represented as monosegmental, one would expect it to be followed most often by the palatal approximant. The items with an approximant have a longer friction duration. What happens, in fact, is that the major par t of the approximant itself is devoiced. Although amplitude is still relatively high, there is a greater reduction than in the case of weak approximant segments. However, it occurs only when the righthand environment is a high front vowel, an approximant, or a fricative. Moreover, each local approximant has to be evaluated efficiently. Replacing by a rational approximant the problem reduces to a periodic case and a similar picture is obtained. The second difference between their patterns concerns the outcome of coalescence for stop+approximant clusters. We have seen that stops followed by an approximant have a prolonged friction interval, and this is especially visible in the voiceless stop. In this section we discuss a more flexible way to construct a greedy approximant. It is usually described as an approximant or a semivowel. The first considers the production of 0 t 0 and 0d 0 in different vocalic or approximant contexts. The two alveolar affricates and the alveolar approximant appeared later.
