Book Description
Systems designers are expressing greater interest in speech-based user interfaces for a variety of civilian and military applications. Such interfaces provide hands free operation and a more natural way for humans to interact with systems. One difficulty with speech-based user interfaces is poor operation in noisy environments such as military operations. The Physiological Sensor, developed at ARL, is an example of an alternative sensor for automatic speech recognition This sensor detects speech by measuring acoustic signals through the speaker's skin. While the signal produced is not typical of that from an airborne acoustic microphone, the possibility exists for using this sensor as a microphone. We investigate several possible methods for using the Physiological Sensor as a microphone for automatic speech recognition.

Book Description
The Army Research Laboratory (ARL) is developing sensor technology to monitor the soldier's voice and physiology by using enhanced acoustic sensors. The physiological sensor consists of liquid or gel contained within a small, conformable, rubber bladder or pad that also includes a hydrophone. This enables the collection of high signal-to-noise ratio cardiac, respiratory, voice, and other physiological data. The pad also minimizes interference from ambient noise because it couples poorly with airborne noise. It is low cost and comfortable to wear for extended periods. When the sensor pad is in contact with a patient's thorax, neck, or temple region, sounds can be immediately and continuously monitored. This can aid in the remote assessment, diagnosis, and treatment of cardiac and respiratory functions, as well as provide human stress and performance indicators such as heart and breath rates, voice stress, and gross motor indicators. The neck sensor picks up the wearer's voice well, with fidelity sufficient to be used as a hands-free voice activation mechanism using speech recognition software, or for voice communications. The pulse is also detectable from the carotid artery, and excellent breath sounds are present as well. This attachment area is often unobstructed by other equipment or clothing, and is easy to attach quickly to a subject.

Book Description
This two-volume set focuses on the interface between physiologic mechanisms and diagnostic human engineering. Today numerous biomedical sensors are commonplace in clinical practice. The registered biosignals reflect mostly vital physiologic phenomena. In order to adequately apply biomedical sensors and reasonably interpret the corresponding biosignals, a proper understanding of the involved physiologic phenomena, their influence on the registered biosignals, and the technology behind the sensors is necessary. The first volume is devoted to the interface between physiologic mechanisms and arising biosignals, whereas the second volume is focussed on the interface between biosignals and biomedical sensors. The physiologic mechanisms behind the biosignals are described from the basic cellular level up to their advanced mutual coordination level during sleep. The arising biosignals are discussed within the scope of vital physiologic phenomena to foster their understanding and comprehensive analysis.

Book Description
The book explores new ways to reconstruct and enhance speech that is compromised by various neuro-motor disorders – collectively known as “dysarthria.” The authors address some of the extant lacunae in speech research of dysarthric conditions: they show how new methods can improve speaker recognition when speech is impaired due to developmental or acquired pathologies; they present a novel multi-dimensional approach to help the speech system both assess dysarthric speech and to perform intelligibility improvement of the impaired speech; they display well-performing software solutions for developmental and acquired speech impairments, and for vocal injuries; and they examine non-acoustic signals and muted nonverbal sounds in relation to audible speech conversion.

Book Description
In this paper, we treated all stages of emotion analysis, from data collection to classification using short-term observations, and evaluated several fusion methods as well as a hybrid decision scheme. We also compared the results from multimodal classification with the unimodal results. As in our earlier work (Kim et al. 2005) where we relied on longer observation phases and a different set of features, the best results were obtained by featurelevel fusion method in combination with feature selection stage. In this case, not only userdependent, but also user-independent emotion classification could be improved compared to the unimodal methods.
