OBJECTIVES Clinicians often base the implementation of therapies on the presence of postural instability in subjects with Parkinson's disease (PD). These decisions are frequently based on the pull test from the Unified Parkinson's Disease Rating Scale (UPDRS). We sought to determine whether combining the pull test, the one-leg stance test, the functional(More)
Acoustic speaker diarization is investigated for situations where a collection of shows from the same source needs to be processed. In this case, the same speaker should receive the same label across all shows. We compare different architectures for cross-show speaker diarization: the obvious concatenation of all shows, a hybrid system combining first a(More)
Exploiting a tissue-conductive sensor – a stethoscopic microphone – the system developed at NAIST which converts Non-Audible Murmur (NAM) to audible speech by GMM-based statistical mapping is a very promising technique. The quality of the converted speech is however still insufficient for computer-mediated communication, notably because of the poor(More)
A randomized controlled trial was conducted on 142 adult male and female patients for primary inguinal hernias by the Shouldice or the Bassini-Kirschner surgical technique. Follow-up after one year revealed 7 recurrences out of 72 patients having had Bassini-Kirschner's operation and three recurrences out of 70 patients having had Shouldice's operation (p =(More)
The NAM-to-speech conversion proposed by Toda and colleagues which converts Non-Audible Murmur (NAM) to audible speech by statistical mapping trained using aligned corpora is a very promising technique, but its performance is still insufficient, mainly due to the difficulty in estimating F 0 of the transformed voice from unvoiced speech. In this paper, we(More)
Although the segmental intelligibility of converted speech from silent speech using direct signal-to-signal mapping proposed by Toda et al. [1] is quite acceptable, listeners have sometimes difficulty in chunking the speech continuum into meaningful words due to incomplete phonetic cues provided by output signals. This paper studies another approach(More)
Non-audible murmur (NAM) is an unvoiced speech received through body tissue using special acoustic sensors (i.e., NAM microphones) attached behind the talkers ear. Although NAM has different frequency characteristics compared to normal speech, it is possible to perform automatic speech recognition (ASR) using conventional methods. In using a NAM microphone,(More)
RÉSUMÉ Afin de récupérer les mouvements des articulateurs tels que les lèvres, la mâchoire ou la langue, à partir du son de parole, nous avons développé et comparé deux méthodes d'inversion basées l'une sur les modèles de Markov cachés (HMMs) et l'autre sur les modèles de mélanges de gaussiennes (GMMs). Les mouvements des articulateurs sont caractérisés par(More)
Appendicitis is a frequently encountered surgical emergency which can be diagnosed by clinical and laboratory criteria. But there are some atypical cases that ultrasound can help to diagnose. From April the 9th 1992 to April the 11th 1993, we have examined by ultrasound 465 patients entered in our hospital for right lower quadrant pain. 190 patients have(More)
