Experiments were conducted to determine the extent to which a fundamental frequency or formant frequency transition influenced segregation of a simultaneous pair of single-formant harmonic complexes. Results showed that even a minute transition facilitated segregation. The effect was larger for formant frequency than fundamental frequency transitions. It is concluded that dynamic aspects of spe...

The present paper consists in replicating Repp and Crowder’s (1990) neutralisation hypothesis according to which the auditory trace left by the first vowel in a pair decays toward a central point in the acoustic space, triggering order effects in perception. Two ‘same-different’ tasks were undertaken by French listeners. A prototype and four satellite tokens were synthesized for ten vowel categ...

OBJECTIVES To investigate at the age of 2 years the effects of childhood recurrent acute otitis media (RAOM) on central auditory processing by using cortical event-related potentials elicited by syllable stimuli. DESIGN During a 1-year period, 22- to 26-month-old children fulfilling the criteria for tympanostomy tube insertion in Oulu University Hospital, Oulu, Finland, were recruited to the ...

In the present study, cortical responses of two sustained Italian vowels, /a/ and /i/, were analyzed in perception and production tasks by using the event-related potential (ERP) technique. First, we showed that the earlier auditory waveform complex, N1/P2, was elicited in both experimental tasks by acoustically presented vowels. More interestingly, the cortical activity of auditory cortex seem...

There is a consensus concerning the view that both auditory and motor representations intervene in the perceptual processing of speech units. However, the question of the functional role of each of these systems remains seldom addressed and poorly understood. We capitalized on the formal framework of Bayesian Programming to develop COSMO (Communicating Objects using Sensory-Motor Operations), a...

We investigate how supervision (in the form of explicit instruction) interacts with distributional learning in the acquisition of the perception of a novel vowel contrast in a second language. An experiment with non-Dutch-speaking Bulgarians reveals that listeners who receive bimodal distributional training without explicit instruction can acquire new Dutch vowel contrasts, and that listeners w...

ABSTRACT Dynamic vocal analysis (DVA) is an auditory-perceptual and acoustic assessment strategy that provides estimates on the biomechanics aerodynamics of production by performing frequency intensity variation tasks using voice spectrography. The objective this experience report to demonstrate use DVA in functionality dysphonic non-dysphonic individuals, with a special focus laryngeal muscula...

This study was designed to identify English speech contrasts that might be appropriate for the computer-based auditory-visual training of Spanish learners of English. It examines auditory-visual and auditory consonant and vowel confusions by Spanish speaking students of English and a native English control group. 36 Spanish listeners were tested on their identification of 16 consonants and 9 vo...
