Variation in lingual coarticulation at certain juncture boundaries.
The acoustic spectra of [m] produced by speakers of American English in various [mV] contexts was studied for coarticulatory variations caused by the [vowel] under conditions of varying juncture boundaries occurring between [m] and [vowel]. Dispersion analysis was used to estimate the coarticulatory variation in [m] spectra. Low level junctures marked by short pauses do not disrupt nasal-vowel coarticulation. However, higher leveljunctures such as between extraposed clauses or phrases and the body of an utterance are more often than not marked with long pauses, and concomitant reduction of nasal-vowel coarticulation.
