EUSIPCO - Improved vocal tract model for Speech synthesis
1996Co-Authors: Minsheng Liu, Arila LacroixAbstract:Speech synthesis of Nasal and non-Nasal Speech sounds are studied on the basis of an improved model where a Nasal tract is included in the vocal tract. The transfer function of the model is analysed. Because of the closure of the oral tract, the three-port adaptor at the velum is reduced to a two-port adaptor, so that the model parameters can be estimated by inverse filtering from the Speech signal. Moreover this method is applied to investigate Nasalization of vowels.

improved vocal tract model for the analysis of Nasal Speech sounds
International Conference on Acoustics Speech and Signal Processing, 1996Co-Authors: Minsheng Liu, Arila LacroixAbstract:This paper presents the extended tube model for the vocal and Nasal tract, in which the velum is described by means of a three-port-adaptor, which can be reduced to a two-port-adaptor. In this way the transfer function is derived, then its properties are investigated, so that this model can be used for the Speech analysis of the Nasal and non-Nasal sounds and can be simply implemented by the inverse filtering method. Moreover the losses in the vocal and Nasal tract are analysed and the shape of the Nasal tract is also estimated.

postnatal growth retardation facial dysmorphism spondylocarpal synostosis cardiac defect and inner ear malformation cardiospondylocarpofacial syndrome a distinct syndrome
American Journal of Medical Genetics Part A, 2010Co-Authors: Sérgio B Sousa, Daniel Sidi, Genevieve Baujat, Arnold Munnich, Deborah Krakow, Veronique Abadie, Damien Bonnet, Valerie CormierdaireAbstract:We report on two unrelated cases born to nonconsanguineous parents with a similar clinical presentation: hypotonia since the neonatal period, severe failure to thrive, postnatal growth retardation, facial dysmorphism, congenital cardiac defects (septal defect and non progressive multiple valve dysplasia), shortened extremities, carpal/tarsal and extensive vertebral synostosis, delayed carpal bone age, deafness, and inner ear malformations. Presently, both patients present with normal psychomotor development. Additional abnormal findings include extra oral frenulum, Nasal Speech, and vesico-ureteral reflux. Molecular analysis in one patient excluded the Noggin gene and Filamin B (FLNB) was excluded in the other patient. Although some features are similar to spondylocarpotarsal synostosis syndrome, the exclusion of FLNB and this constellation of findings suggest a new entity, closely similar to an autosomal dominant condition reported by Forney et al. 1966 in a unique family. Identification of similarly affected patients should aid in the further elucidation of this syndrome. © 2010 Wiley-Liss, Inc.

Nasal Speech sounds detection using connectionist temporal classification
International Conference on Acoustics Speech and Signal Processing, 2018Co-Authors: Milos Cernak, Sibo TongAbstract:Phone attributes, known also as distinctive or phonological features, belong to important classification of the Speech sounds used in automatic Speech processing. Training of conventional phone attribute detectors (classifiers), either based on acoustic measurements or deep learning approaches, requires decent phone boundary segmentation. This paper proposes a solution to train a phone attribute detector without phone alignment using an end-to-end phone attribute modeling based on the connectionist temporal classification. Experiments, performed for the Nasal phone attribute on the LibriSpeech database, confirm that the proposed system outperforms conventional deep neural network detector, trained even on the same training data. Further improvements are observed with more training data. Conventional complex system that consists of feature extraction, phone force-alignment and deep neural network training is replaced by a more simpler Python package based on PyTorch, released as open-source.
