SUMMARY:Speech perception across the adult lifespan with clinically normal hearings by Christian FULLGRABE
DESCRIPTION:Speech perception across the adult lifespan with clinically normal hearings by Christian FULLGRABE (MRC Institute of Hearing Research\, Nottingham\, UK)\nSubjective reports suggest that older listeners experience increased listening difficulties in noisy environments\, and experimental investigations seem to confirm this age-dependent deficit. However\, older persons are generally unaware of their peripheral hearing status (i.e.\, the presence of a hearing loss) and most published studies used lax audiometric inclusion criteria. Hence\, lower speech intelligibility could\, at least partially\, be explained by a reduction in audibility with age. Also\, most aging studies limited their age comparison to groups of ""young"" (e.g. ≤ 30 years) and ""older"" listeners (e.g. ≥ 60 years)\, making it impossible to pinpoint the onset of the putative age effect. This talk will present two cross-sectional investigations of central age effects on speech perception\, using participants with clinically normal hearing. Performance on supra-threshold temporal-processing and a battery of cognitive tasks (including tests of processing speed\, working memory and attention) was assessed\, and compared with speech identification in quiet and in different (steady and fluctuating) background noises. To determine when during adulthood a decline with age in these abilities first becomes apparent\, participants were sampled continuously from the entire adult age range (18-91 years). Despite a large individual variability\, the results show an age-dependent decline in speech identification\, especially above 70 years. Sensitivity to temporal information and cognitive performance deteriorated as early as middle age\, and both correlated with speech-in-noise perception.

SUMMARY:Runt yak wahoo : baboon speak by Caralyn KEMP
DESCRIPTION:Runt yak wahoo : baboon speak by Caralyn KEMP (BLRI)\nPrimates vocalise to maintain contact with conspecifics\, warn of predators\, alert group members to food and to advertise territory\, sexual availability and size\, but we know surprisingly little about how and why these calls are produced. Can they be varied and is this context dependent? Are these calls vocal responses to emotional states or can they be produced voluntarily? How does the production of these calls compare to human speech? Studying these questions not only helps us to understand what our closest relatives are saying\, but also helps us to understand the evolution of our own speech. As part of a larger study considering these questions\, I am examining the vocalisations of a captive group of Guinea baboons at the Primate Cognition and Behavior Platform in Rousset. The main goal of this aspect of the project is to produce a large-scale database in order to 1) characterise the vocal repertoire of this baboon species\, 2) determine the acoustic features of the vocalisations\, and 3) test the descriptive adequacy of existing categories. Determining the precise repertoire of baboon vocalisations will allow us to specify the 'acoustic space' that the vocal track of baboons can produce and how this compares to human vowel production. Taking into consideration the social context in which these vocalisations are produced and how specific situations alter vocal production\, we aim to determine whether the baboons are capable of producing these calls voluntarily.

SUMMARY:Sonifying handwriting movements for the diagnosis and the rehabilitation of movement disorders by Jérémy DANNA
DESCRIPTION:Sonifying handwriting movements for the diagnosis and the rehabilitation of movement disorders by Jérémy DANNA (BLRI)\nExcept for the slight scratching of the pen\, handwriting is a silent activity. Transforming it into an audible activity might sound curious. However\, because audition is particularly appropriate for the perception of fine temporal and dynamical differences\, using sounds to gain information about handwriting movements seems judicious. We use the sonification that consists in adding synthetic sounds to silent movements in order to provide support for information processing activities. The idea is to associate a melodious sound\, which flows\, to a fluent handwriting\, and a dissonant sound\, which squeaks\, to a jerky handwriting. By sonifying the relevant variables of handwriting in dysgraphic children or in Parkinsonian patients\, it could be possible to detect their handwritings troubles 'by ear' only.\n\nMy talk will be organized in two parts. First\, I will expose an experiment showing that adding relevant auditory information is sufficient for discriminating the handwriting of dysgraphic children and the skilled handwriting of proficient children 'by ear' only. I will also present an experiment in progress in which real-time auditory feedback are supplied to help dysgraphic children to improve their handwriting movements. Secondly\, I will present the BLRI project that consists in using computerized analysis and sonification of handwriting movements for the early diagnosis of Parkinson Disease.
