review bone conduction devices and contralateral routing of sound systems in single sided deafness
Laryngoscope, 2015Co-Authors: Jeroen P M Peters, Adriana L Smit, Inge Stegeman, Wilko GrolmanAbstract:OBJECTIVES/HYPOTHESIS: Systematically review the literature on the clinical outcome of bone conduction devices (BCD) and contralateral routing of sound systems (CROSS) for patients with single-sided deafness (SSD). DATA SOURCES: PubMed, Embase, Cochrane Library, and CINAHL databases were searched up to April 7, 2014. REVIEW METHODS: All studies investigating BCD and CROSS for patients with SSD on Speech perception in noise, sound localization, or quality of life were selected and critically appraised. RESULTS: In total, 46 articles were retrieved, of which six satisfied the eligibility criteria. Critical appraisal showed that five studies (n = 91) carried a moderate to high directness of evidence and a low to moderate risk of bias. Subsequently, study characteristics and outcome measurements were extracted. Due to large heterogeneity between studies, pooling of data was not feasible. Studies did not show a clear advantage of BCD or CROSS on Speech perception in noise. BCD and CROSS lead to the same sound localization ability as the unaided condition. Quality of life did not differ significantly between conditions; however, subjective Speech Communication did improve. CONCLUSION: No high level of evidence studies compare BCD and CROSS in patients with SSD. Literature showed no beneficial effect of BCD or CROSS regarding Speech perception in noise and sound localization. Subjective Speech Communication demonstrated a moderate improvement with BCD and CROSS. High evidence studies comparing all treatment options for single-sided deafness should be conducted.

Statistical Voice Conversion Techniques for Body-Conducted Unvoiced Speech Enhancement
IEEE Transactions on Audio Speech and Language Processing, 2012Co-Authors: Tomoki Toda, Mikihiro Nakagiri, Kiyohiro ShikanoAbstract:In this paper, we present statistical approaches to enhance body-conducted unvoiced Speech for silent Speech Communication. A body-conductive microphone called nonaudible murmur (NAM) microphone is effectively used to detect very soft unvoiced Speech such as NAM or a whispered voice while keeping Speech sounds emitted outside almost inaudible. However, body-conducted unvoiced Speech is difficult to use in human-to-human Speech Communication because it sounds unnatural and less intelligible owing to the acoustic change caused by body conduction. To address this issue, voice conversion (VC) methods from NAM to normal Speech (NAM-to-Speech) and to a whispered voice (NAM-to-Whisper) are proposed, where the acoustic features of body-conducted unvoiced Speech are converted into those of natural voices in a probabilistic manner using Gaussian mixture models (GMMs). Moreover, these methods are extended to convert not only NAM but also a body-conducted whispered voice (BCW) as another type of body-conducted unvoiced Speech. Several experimental evaluations are conducted to demonstrate the effectiveness of the proposed methods. The experimental results show that 1) NAM-to-Speech effectively improves intelligibility but it causes degradation of naturalness owing to the difficulty of estimating natural fundamental frequency contours from unvoiced Speech; 2) NAM-to-Whisper significantly outperforms NAM-to-Speech in terms of both intelligibility and naturalness; and 3) a single conversion model capable of converting both NAM and BCW is effectively developed in our proposed VC methods.

a Speech Communication aid system for total laryngectomies using voice conversion of body transmitted artificial Speech
Journal of the Acoustical Society of America, 2006Co-Authors: Keigo Nakamura, Tomoki Toda, Hiroshi Saruwatari, Kiyohiro ShikanoAbstract:There are several problems associated with using existing electrolarynxes. For example, the loud volume of the device itself might disturb smooth interpersonal Communication, and its generated Speech is also unnatural. To improve the quality of Speech Communication using such a medical device, this paper proposes a novel Speech Communication aid system for total laryngectomies. This system detects articulated Speech caused by a new sound source as an alternative to the existing electrolarynx through the soft tissues of the head with a nonaudible murmur (NAM) microphone attached to the surface of the skin [Nakajima et al, Proc. InterSpeech 2005, pp. 293–296 (2005)]. The new sound source outputs signals of extremely low energy that cannot be heard by people near the speaker. Such body‐transmitted artificial Speech is converted to a more natural voice by statistical voice conversion [T. Toda and K. Shikano, Proc. InterSpeech 2005, pp. 1957–1960 (2005)]. The performance of the proposed system is evaluated in ...

cosmo communicating about objects using sensory motor operations a bayesian modeling framework for studying Speech Communication and the emergence of phonological systems
Journal of Phonetics, 2015Co-Authors: Clement Moulinfrier, Julien Diard, Jeanluc Schwartz, Pierre BessiereAbstract:While the origin of language remains a somewhat mysterious process, understanding how human language takes specific forms appears to be accessible by the experimental method. Languages, despite their wide variety, display obvious regularities. In this paper, we attempt to derive some properties of phonological systems (the sound systems for human languages) from Speech Communication principles. We introduce a model of the cognitive architecture of a communicating agent, called COSMO (for “Communicating about Objects using Sensory–Motor Operations') that allows a probabilistic expression of the main theoretical trends found in the Speech production and perception literature. This enables a computational comparison of these theoretical trends, which helps us to identify the conditions that favor the emergence of linguistic codes. We present realistic simulations of phonological system emergence showing that COSMO is able to predict the main regularities in vowel, stop consonant and syllable systems in human languages.

adverse conditions improve distinguishability of auditory motor and perceptuo motor theories of Speech perception an exploratory bayesian modeling study
Language and Cognitive Processes, 2012Co-Authors: Clement Moulinfrier, Jeanluc Schwartz, Pierre Bessiere, Raphael Laurent, Julien DiardAbstract:In this paper, we put forward a computational framework for the comparison between motor, auditory, and perceptuo-motor theories of Speech Communication. We first recall the basic arguments of these three sets of theories, either applied to Speech perception or to Speech production. Then we expose a unifying Bayesian model able to express each theory in a probabilistic way. Focusing on Speech perception, we demonstrate that under two hypotheses, regarding Communication noise and inter-speaker variability, providing perfect conditions for Speech Communication, motor, and auditory theories are indistinguishable. We then degrade successively each hypothesis to study the distinguish- ability of the different theories in ''adverse'' conditions. We first present simulations on a simplified implementation of the model with mono-dimensional sensory and motor variables, and secondly we consider a simulation of the human vocal tract providing more realistic auditory and articulatory variables. Simulation results allow us to emphasise the respective roles of motor and auditory knowledge in various conditions of Speech perception in adverse conditions, and to suggest some guidelines for future studies aiming at assessing the role of motor knowledge in Speech perception.
