[已关闭问题] 关于自由变体
这段话不太懂，厉害的翻译一下：If two sounds occurring in the same environment do not contrast; namely, if the substitution of one for the other does not generate a new word form but merely a different pronunciation of the same word, the two sounds then are said to be in “free variation”. The plosives, for example, may not be exploded when they occur before another plosive or a nasal (e. g., act, apt, good morning). The minute distinctions may, if necessary, be transcribed in diacritics. These unexploded and exploded plosives are in free variation. Sounds in free variation should be assigned to the same phoneme.
