This paper examines how ordinary listeners, naïve with respect to the phonetics and phonology of prosody, perceive the location of prosodic boundaries that demarcate speech “chunks” and prominences that serve a “highlighting” function, in spontaneous speech (Buckeye corpus). Over 70 naïve listeners marked the locations of prominences and boundaries in a(More)
Two transcribers have labeled prosodic events independently on a subset of Switchboard corpus using adapted ToBI (TOnes and Break Indices) system. Transcriptions of two types of pitch accents (H* and L*), phrasal accents (Hand L-) and boundary tones (H% and L%) encoded independently by two transcribers are compared for intertranscriber reliability. Two(More)
Does prosody help word recognition? This paper proposes a novel probabilistic framework in which word and phoneme are dependent on prosody in a way that reduces word error rates (WER) relative to a prosody-independent recognizer with comparable parameter count. In the proposed prosody-dependent speech recognizer, word and phoneme models are conditioned on(More)
This study examines the effects of prosody on the acoustic cues of stop consonants, based on speech from the Boston University Radio News corpus. An investigation of VOT, f0, closure duration, burst amplitude and spectral characteristics provide evidence for a primary effect of accent (a level of phrasal prominence) on these measures as cues to stop voicing(More)
This paper describes automatic speech recognition systems that satisfy two technological objectives. First, we seek to improve the automatic labeling of prosody, in order to aid future research in automatic speech understanding. Second, we seek to apply statistical speech recognition models of prosody for the purpose of reducing the word error rate of an(More)
This paper presents a novel approach to the automatic detection of pitch accent in spoken English. The approach that we propose is based on a time-delay recursive neural network (TDRNN), which takes into account contextual information in two ways: (1) a delayed version of prosodic and spectral features serve as inputs which represent an explicit trajectory(More)
This study investigates whether the stress foot is a planned timing unit in American English, by examining the durational characteristics of the foot in three different prosodic contexts i) within an intermediate phrase, ii) across an intermediate phrase and iii) across an intonational phrase. The results show that as the number of syllables in a foot(More)
This paper reports on an acoustic experiment to investigate prosodic and segmental factors governing the degree of spirantization of intervocalic /g/ in Castilian Spanish. Significant variation in the degree of /g/-spirantization, measured here in terms of relative acoustic energy, is found to be conditioned by stress and the quality of the vowels adjacent(More)
