broad transcription
【正确答案】：Broad transcription is one of the two ways to transcribe speech sounds. It is the transcription with letter-symbols only. It is normally used in dictionaries and teaching textbooks. For example, the symbol [I] is used for the sound [1] in words like leaf [li:f], feel [fi:l], build [bild], and health [helθ], though the [1] in all these four sound combinations differ slightly.
