That is, the degree to which a person might take a machine’s perspective into account. Our study aims to identify whether users produce allocentric or egocentric language within speech-based HMD when there is asymmetry in the information available to both partners. Through an adapted referential communication task, we manipulated the presence or absence of visual distractors and occlusions, similarly to previous referential tasks used in psycholinguistic research. Results show that people are sensitive to the presence of distractors and occlusions and tend to produce more informative expressions to help machine partners account for the visual asymmetries. We discuss the fndings on how allocentric production in HMD is explained by how the division of labour manifests in spoken HMD. The fndings further our understanding of the language production mechanis...

Clearly the ability to accurately determine “what works” and “what doesn’t” offers valuable and essential information to patient care and service delivery. Concerns of this type have led to an ever-increasing awareness of “outcomes” as an important and necessary health-care metric. Interest in outcomes research is not a new area of inquiry, and it has expanded significantly over the past 20 years. Understandably, speech-language pathology as a profession has long centered its focus on verbal communication. Despite the obvious relevance of gathering objective voice and speech measures in those treated for laryngeal cancer, such measures may be inadequate in documenting rehabilitation success. That is, measures of voice and speech must be viewed within a larger context of postlaryngectomy communicative functioning. Therefore, this chapter provides an overview of issues specific to the continued need to document outcomes in postlaryngectomy voice and speech production.

Because of the loss of the larynx and the requirement that one acquires a new voicing source, SI will always be reduced in this population. It is well-recognized that SI will be impacted by a variety of factors specific to the speaker, as well as the listener. However, while SI has been widely considered in those who have undergone total laryngectomy and use either the artificial electrolarynx or esophageal speech or have undergone tracheoesophageal voice restoration, consideration of collective factors on assessments of intelligibility has not yet been fully addressed. Thus, this chapter provides information pertaining to SI in alaryngeal speakers. In doing so, a variety of factors that underlie fundamental changes in alaryngeal speech production that will have a direct impact on SI are...

In seeking to meet this objective, several aspects of instruction are addressed. This includes a description of the structures used for the esophageal “voicing” process and its utility for this postlaryngectomy method of alaryngeal speech. Anatomical, physiological, and aerodynamic features are described. Relationships between physical structures and physiologic events are described. A framework that outlines the procedural aspects of teaching esophageal speech from the acquisition of one’s first esophageal sound to functional communicative use of the method is then addressed. A major component of this chapter is directed toward advocacy for collaborative efforts of instruction between the speech-language pathologist (SLP) and highly proficient esophageal speakers who can serve in the role of a lay instructor. Given an increasing lack of qualified esophageal speech teachers in the current era, we encourage collaborative efforts between the SLP and proficient esophageal speakers. Such collaborative efforts between the professional and laryngectomee community may foster improved instruction and facilitate better outcomes in those who wish to acquire esophageal speech.

It is believed that this reduction in F0 is a result of edema of the vocal folds caused by tobacco smoke. This study investigated F0 changes during smoking and no‐smoking periods. Data were collected before, during, and after a 40‐hour period of no‐smoking. Analysis of the voice recordings showed a rise in voice F0 for the two smoking subjects during the 40‐hour no‐smoking period. Age‐ and sex‐matched control subjects did not show a rise in their F0 during the same tasks. Results suggest that the pitch‐lowering effects of cigarette smoking may be reversed after as few as 40 hours of smoking cessation.

Using this method, five normal children (6–12 years of age) and five normal young adults (21–34 years of age) were assessed. Evaluation of this simplified PGG acquisition method revealed that PGG waveforms were obtained without difficulty from all 10 subjects. The method outlined is safe and simple for use with children and adults, as well as time-effective. These findings suggest that utilization of PGG in the clinical setting is quite feasible when the current procedure is employed. Additionally, issues pertaining to the effectiveness and feasibility of using this method as a standard clinical procedure for diagnostic purposes are discussed.

Conservation or partial laryngectomy surgical procedures seek to remove malignant tissue but also preserve some laryngeal structures, particularly when larger tumors exist. These procedures attempt to maintain both sphincteric and phonatory function of the postoperative larynx. The extent of surgical resection does not always correlate well with a patient's postoperative voice outcome. Thus, preconceived notions of postsurgical vocal function are often problematic. This tutorial discusses: (a) the rationale underlying the use of conservation laryngectomy procedures, (b) the clinical identification of the anatomical and subsequent physiologic basis of voice change following conservation laryngectomy, (c) the potential for functional compensation by the patient following conservation surgery, and (d) a rationale for voice refinement using treatment meth...

Specifically, the three most common alaryngeal speech methods are presented in relation to typical speech intelligibility outcomes. Factors that interact with intelligibility highlight how formal measures of intelligibility are necessary, but insufficient, for determining communicative success. A multidimensional context in which the communicative dyad is presented as an additional factor must be considered. In this paper, we outline several clinical examples that highlight the importance of this factor and its implications for rehabilitation.

Existing empirical research alludes to the stigmatization of falls for older adults, but until now the explicit link between the study of falls and stigma has not been made. After applying the concepts of identity threat, modified labeling theory, and attribution theory, the research implications of stigma on an older adult's willingness to report and discuss falls will be outlined. As many research investigations use the number of prior falls to assign individuals to study groups, the influence of stigma may be widespread and confounding research findings. By better recognizing and understanding the contribution of stigma to the willingness of older adults to report and discuss falls, we will be better able to mitigate its effects.
