In this work, we cons ider that a syllable is at syntactic boundary when it is at the beginning or at the end of a constituent, minor or major. Our data indicate that, in Spanish, syllables that are at bo undaries announce so by having a longer duration than syllables that are not in this positi on. Therefore, we regard that syllabic duration is one of the prosodic strategies to mark the boundary of a syntactic constituent. We will try to show if the same temporal strategy i s used in all the rates, or if it is different depending on the rate. We under stand by speech rate the time utilized by a speaker to utter a determined amount of phonetic syllables, without including pauses; the more syllables a speaker produces, the faster his speech rate is.esSyllableDuration (music)Syllabic verseMathematicsSpeech recognitionLinguisticsarticle
