“…Syntax processing and semantic lexicon might be altered independently, but they remain difficult to evaluate given the severe phonological alterations and the absence of baseline assessments in these young children. Prosody processing seems relatively spared (Kim Dufor, Ferragne, Dufor, Astésano, and Nespoulous, 2012). Clinical observations report that environmental sound identification is altered in the acute phase of the disease in the most severe cases (e.g., global auditory agnosia, see Cockerell et al, 2011), and that it recovers earlier than does word identification (Kaga, 1999;Korkman, Granström, Appelqvist, and Liukkonen, 1998).…”

Verbal-auditory agnosia and aphasia are the most prominent symptoms in Landau-Kleffner syndrome (LKS), a childhood epilepsy that can have sustained long-term effects on language processing. The present study provides the first objective investigation of music perception skills in four adult patients with a diagnosis of LKS during childhood, covering the spectrum of severity of the syndrome from mild to severe. Pitch discrimination, short-term memory for melodic, rhythmic and verbal information, as well as emotion recognition in music and speech prosody were assessed with listening tests, and subjective attitude to music with a questionnaire. We observed amusia in 3 out of 4 patients, with elevated pitch discrimination thresholds and poor short-term memory for melody and rhythm. The two patients with the most severe LKS had impairments in music and prosody emotion recognition, but normal perception of emotional intensity of music. Overall, performance in music processing tasks was proportional to the severity of the syndrome. Nonetheless, the four patients reported that they enjoyed music, felt musical emotions, and used music in their daily life. These new data support the hypothesis that, beyond verbal impairments, cerebral networks involved in sound processing and encoding are deeply altered by the epileptic activity in LKS, well after electrophysiological normalization.

“…Narzędzie to charakteryzuje się dbałością o dobór materiału leksykalnego pod względem frekwencyjności występowania jednostek leksykalnych w języku oraz ich budowy morfologicznej. Nowością w teście, w stosunku do powszechnie stosowanych narzędzi, jest dokonywana przez dziecko, na podstawie relacji między charakterystyką prozodyczną a zawartością semantyczną, ocena słyszanego zdania pod względem jego zrozumiałości i poprawności oraz próba korekty błędów podczas własnej realizacji zdania [29].…”

Celem artykułu jest prezentacja narzędzi przeznaczonych do oceny słuchu prozodycznego i ekspresji prozodii mowy. Przedmiotem opisu i oceny są przede wszystkim te narzędzia, które są najczęściej wykorzystywane w badaniach naukowych i praktyce klinicznej.Analizowany materiał stanowią publikacje o zasięgu międzynarodowym i krajowym (artykuły, pozycje zwarte, testy i instrukcje do testów). Większość prezentowanych w artykule narzędzi pozwala na dokonanie wieloaspektowej oceny cech i jednostek suprasegmentalnych, lecz są wśród nich i takie, które przeznaczone są do diagnozy tylko wybranych zjawisk prozodycznych. Za szczególnie przydatne w praktyce klinicznej należy uznać te narzędzia, które umożliwiają odrębną diagnozę słuchu prozodycznego i realizacji prozodii.

“…The PURR algorithm has been used by various authors to evaluate the role of prosody in the perception of foreign accent [15], emotion [16] or speaking styles [17]. Similarly, other studies have used delexicalization methods based on the modulation of f0 on pure tones [18], or on synthetic 'hum' stimuli [19] as implemented in Praat [20].…”

Perceptual evaluation of non-controlled emotional speech requires delexicalization to neutralize semantic variation. However, most existing methods imply losing spectral cues crucial to emotional attribution, related to both laryngeal and supralaryngeal settings. We propose a method relying on voice morphing to retain part of the spectral information of the original stimuli, as an additional step to diphone synthesis delexicalization. After previous assessment of intelligibility loss, this study evaluates the naturalness of angry and neutral expressions in French films, delexicalized using low-pass filtering and the proposed method implemented with MBROLA and STRAIGHT. Results show that morphing-based delexicalization, which leads to accurate emotional attribution, is rated with a higher degree of naturalness than low-pass filtering. Implications for research in affective speech are discussed with regards to other delexicalization methods proposed in the literature.
