Variation Of Duration And Fundamental Frequency

Decent Essays

Variation in duration and fundamental frequency and assimilation in different segmental contexts This paper will examine two things. The first is the way duration and fundamental frequency vary according to phrasal position. The second is how F2 transitions for /d/ and /g/ change according to adjacent segmental context. From this, I will determine whether categorical assimilation has occurred in fad bag and fag bag. 1. Introduction 1.1 Duration Much research has been carried out concerning the duration of sentences. One of the main findings is that there is a lengthening effect in the rhyme of the final syllable (Wightman et al., 1992). There are many other factors that contribute to duration, but this is the most prominent effect. According to Wightman, this effect is caused by preboundary lengthening. This is the lengthening of segments prior to a prosodic boundary. Another cue is the insertion of a pause at major boundaries (Wightman et al., 1992). Alternative research, carried out by Lehiste in 1974, concerned the rate of speech when phrases contain a larger number of words. Lehiste found out that the duration of words in the sentence “Say… instead” was longer than the same word in the sentences “Sometimes it’s useful to say the word … instead” and “The word … is sometimes a useful example”. She concluded that the length of the utterance had a greater effect on the duration of the words than the number of syllables preceding or following the word. Lehiste also
