Book excerpt: As clinicians and researchers, it is our ultimate goal to improve our patients' quality of life. This goal is achieved through reliable measurements such as speech intelligibility, which is a standard assessment of a patient's impairment level. Attempts to correlate this measurement with a patient's daily communication outside the clinic have been weak or uncertain. In this study we explore the correlation between speech intelligibility and self-report measures in a population of head and neck cancer patients, alaryngeal tracheoesophageal speakers (TEP). Participants: 24 individuals using TEP, 66 naïve listeners who performed intelligibility ratings of the speakers in quiet and in noise. The strength of these relationships was compared across the quiet and noise conditions. There was a weak correlation (r =0.201 and r= 0.003) between speech intelligibility in quiet and self-report measures. A slightly stronger correlation (r = 0.435 and r=0.311) was found between speech intelligibility in noise and self-report measures. The results of the study suggest that intelligibility in noise is a better predictor of self-rated communication function than intelligibility in quiet.

Available in PDF, EPUB and Kindle. Book excerpt: Malignancies involving structures of the head and neck frequently impact the most fundamental aspects of human existence, namely, those functions related to voice and speech production, eating, and swallowing. Abnormalities in voice production, and in some instances its complete loss, are common following treatment for laryngeal (voice box) cancer. Similarly, speech, eating, and swallowing may be dramatically disrupted in those where oral structures (e.g., the tongue, jaw, hard palate, pharynx, etc.) are surgically ablated to eliminate the cancer. Consequently, the range and degree of deficits that may be experienced secondary to the treatment of head and neck cancer (HNCa) are often substantial. This need is further reinforced by the Centers for Disease Control and Prevention who have estimated that the number of individuals who will be newly diagnosed with HNCa will now double every 10 years. This estimate becomes even more critical given that an increasing number of those who are newly diagnosed will be younger and will experience the possibility of long-term survival post-treatment. Contemporary rehabilitation efforts for those treated for HNCa increasingly demand that clinicians actively consider and address multiple issues. Beyond the obvious concerns specific to any type of cancer (i.e., the desire for curative treatment), clinical efforts that address physical, psychological, communicative, and social consequences secondary to HNCa treatment are essential components of all effective rehabilitation programs. Comprehensive HNCa rehabilitation ultimately seeks to restore multiple areas of functioning in the context of the disabling effects of treatment. In this regard, rehabilitation often focuses on restoration of function while reducing the impact of residual treatment-related deficits on the individual’s overall functioning, well-being, quality of life (QOL), and ultimately, optimize survivorship. Regardless of the treatment method(s) pursued for HNCa (e.g., surgery, radiotherapy, chemoradiation, or combined methods), additional problems beyond those associated with voice, speech, eating and swallowing frequently exist. For example, post-treatment changes in areas such as breathing, maintaining nutrition, limitations in physical capacity because surgical reconstruction such as deficits in shoulder functioning, concerns specific to cosmetic alterations and associated disfigurement, and deficits in body image are common. Those treated for HNCa also may experience significant pain, depression, stigma and subsequent social isolation. Concerns of this type have led clinicians and researchers to describe HNCa as the most emotionally traumatic form of cancer. It is, therefore, essential that clinicians charged with the care and rehabilitation of those treated for HNCa actively seek to identify, acknowledge, and systematically address a range of physical, psychological, social, and communication problems. Efforts that systematically consider this range of post-treatment sequelae are seen as critical to any effort directed toward enhanced rehabilitation outcomes. Actively and purposefully addressing post-treatment challenges may increase the likelihood of both short- and long-term rehabilitation success in this challenging clinical population. Current information suggests that successful clinical outcomes for those with HNCa are more likely to be realized when highly structured, yet flexible interdisciplinary programs of care are pursued. Yet contemporary educational resources that focus not only on management of voice, speech, eating, and swallowing disorders, but also address issues such as shoulder dysfunction due to neck dissection, the significant potential for cosmetic alterations can offer a much broader perspective on rehabilitation. Contemporary surgical treatment frequently involves reconstruction with extensive procedures that require donor sites that include both soft tissue from a variety of locations (e.g., forearm, thigh, etc.), as well as bone (e.g., the scapula). Collectively, resources that address these issues and many other concerns and the resultant social implications of HNCa and its treatment can serve to establish a comprehensive framework for clinical care. Consequently, providing a highly specialized and comprehensive educational resource specific to HNCa rehabilitation is currently needed. The proposed edited book is designed to address this void in a single authoritative resource that is also accessible to the clinical readership. Integral to this proposed book is information that guides clinical approaches to HNCa rehabilitation, in addition to offering emphasis on the direct impact of changes in voice, speech, and swallowing and the impact of such losses on outcomes. Finally, while several other published sources currently exist (see attached list), the emphasis of these books is directed either toward the identification and diagnosis of malignant disease, clinical and surgical pathology, associated efforts directed toward biomedical aspects of cancer and its treatment, or those with a focus on a single clinical problem or approach to rehabilitation. Therefore, the content of the proposed multi-chapter text centers on delivering a systematically structured, comprehensive, and clinically-oriented presentation on a range of topics that will provide readers at a variety of levels with a strong, well-integrated, and empirically driven foundation to optimize the clinical care of those with HNCa. The primary audience for this textbook is undergraduate and graduate-level students in Speech-Language Pathology, as well as practitioners, especially hospital-based practitioners, in Speech-Language Pathology; other key audiences include junior and senior level otolaryngology residents and fellows, translational researchers in head and neck cancer, related medical specialists (e.g., radiation oncology), oncology nurses, and potentially other rehabilitation professionals such as occupational therapists, counseling psychologists, social workers, and rehabilitation counselors.
Book Synopsis The Effect of Noise on Speech Intelligibility and Perceived Listening Effort for Speakers with Head and Neck Cancer by : Holly Durr

This book was released on 2019 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: Patients treated for head and neck cancer (HNC) often experience significant difficulties in verbal communication, which may lead to reduced quality of life (Dwivedi et al., 2009). The purpose of this study was to determine the effect of different levels of background noise on a) speech intelligibility and b) perceived listening effort in speakers treated for HNC (excluding laryngeal cancer) with intact or impaired speech. This study also sought to identify the relative contribution of background noise, speech intelligibility, and speaker severity on perceived listening effort. Methods: 10 speakers treated for nasal, oral, or oropharyngeal cancer were: a) 100% intelligible in quiet and did not exhibit any imprecise phonemes (n=5; speakers with intact speech); or, b) 100% intelligible in quiet, but exhibited imprecise phonemes (n=5; speakers with impaired speech). Six sentences of increasing length from each speaker were included to assess speech intelligibility and perceived listening effort (Speech Intelligibility Test; Yorkston et al., 1996). 30 inexperienced listeners participated by listening to these sentences under 3 noise conditions: quiet, +7 dB SNR, and +5 dB SNR. For each sentence, listeners completed two tasks: (1) transcription; and (2) a rating of perceived listening effort. Results: All speakers exhibited worse speech intelligibility and increased demands on perceived listening effort with increased background noise. There was a significant interaction between speaker group and noise. While there was a stronger effect for imprecise speakers (significant differences from one noise condition to the next), control speakers appeared to plateau from +7 dB SNR to + 5 dB SNR. Noise, speech intelligibility, and speaker severity predicted 59% of the variance in perceived listening effort ratings. Conclusions: Speakers with mild speech impairment experienced greater deficits in the two levels of noise than control speakers with intact speech, above and beyond what might be expected from noise alone. This study highlights the vulnerability of those with mild communication disorders secondary to HNC in these relatively low levels of background noise. Listeners tolerated increased background noise for control speakers but not speakers with imprecise speech. Given that many speakers may present as intelligible but face significant penalties in the presence of noise, measures in quiet do not appear to capture the barriers these patients face. Assessment, education, counseling, and treatment that is informed by functional contexts (including background noise) would be beneficial for these patients.

This book was released on 1955 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was undertaken to determine the relationships between talker intelligibility in noise and several voice variable measures derived from intensity, duration and pitch analyses of several speech samples. In addition, the best combination of the voice variables for predicting speech intelligibility in noise was determined. A talker intelligibility score as well as measures on 14 speech variables were determined from an analysis of speech samples obtained from 88 subjects. Product-moment intercorrelations among all the variables were computed. All the relationships between talker intelligibility in noise and the voice variables investigated were found to be linear. Mean syllable intensity and mean syllable duration were found to make the highest contribution to talker intelligibility scores. When combined with other speech variables, intensity and duration were most highly correlated with pitch variability. A multiple correlation coefficient of 0.88 was found for the relationship between talker intelligibility in noise and mean syllable intensity, mean syllable duration and pitch variability. (Author).

This book was released on 1951 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation isolates those variables which seem to change intelligibility in military situations in which a talker must compete with the noise of planes, gunfire, and other battle confusion. Analyses were made of the voices of both good and poor speakers. The variables compared were intensity, speech time, voice quality, and pitch factors. Loudness was the most significant single factor that differentiated high and low intelligibility. Increased loudness improves intelligibility. Syllable and word duration affected intelligibility. A longer duration helps intelligibility. The other voice variables did not seem to be important. (Author).

Abstract: Abstract of dissertation entitled Effects of speech and noise on Cantonese speech intelligibility submitted by MAK Cheuk Yan, Charin for the degree of Master of Science in Audiology at the University of Hong Kong in May 2006 The present study was conducted to examine if the increase in S/N ratio would enhance Cantonese speech intelligibility, and to investigate the effect of speech and noise levels above normal conversational level on speech intelligibility in Cantonese speakers. Sixteen normal-hearing participants, sixteen participants with mild hearing loss and fifteen participants with moderate hearing loss were evaluated. The test ear of each participant was randomly selected. Speech recognition scores were measured using the Cantonese Hearing In Noise Test (CHINT) at six noise levels of 77, 81, 85, 89, 93 and 97 dBA and five signal-to-noise (S/N) ratios of -4, -1, +2, +5 and +8 dB. The data were analyzed to investigate how speech intelligibility was affected with various S/N ratios at the same noise level, and how speech intelligibility was affected at different noise levels under the same S/N ratio. Results indicated that the normal-hearing group performed better than the two hearing-impaired groups at any noise levels or S/N ratios. Speech recognition scores were significantly better at higher S/N ratios than at lower S/N ratios in all three groups. No significant differences in the mean scores were, however, noted within the same group of vi participants as the noise levels increased, contradicted with the results from earlier studies. The findings were compared to those of previous studies in terms of the range of speech and noise levels, the speech materials, and the scoring methods used in different studies. Directions for future research, such as adopting a wider range of noise levels and using monosyllabic speech materials, were also explored. vii DOI: 10.5353/th_b3798979 Subjects: Speech, Intelligibility of Speech perception Audiometry

Book Synopsis Factors Affecting Speech Intelligibility Improvement with Exposure to Reverberant Room Listening Environments by : Eugene Brandewie
Download or read book Factors Affecting Speech Intelligibility Improvement with Exposure to Reverberant Room Listening Environments written by Eugene Brandewie and published by . This book was released on 2012 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Speech intelligibility has been found to improve with prior exposure to a reverberant room environment. It is believed that perceptual mechanisms help maintain accurate speech perception under these adverse conditions. Potential factors underlying this speech enhancement effect were examined in three experiments. Experiment 1 studied the time course of speech intelligibility enhancement in multiple room environments. Carrier phrases of varying lengths were used to measure changes in speech intelligibility over time. Results showed an effect of speech enhancement with a time course that varied with the signal-to-noise ratio between the speech and a broad-band noise masker. Additionally, greater speech enhancement was found for reverberant environments compared to anechoic space, which suggests that a de-reverberation mechanism in the auditory system may enhance the temporal processing of speech. Experiment 2 examined the influence of the specific source and listener position within the room environment on speech enhancement. Source and listener configurations in three virtual room environments were altered to create a disparity between the position of a carrier phrase and a following speech target. Results showed robust effects of speech enhancement when the source and listener configuration were mismatched which suggests that speech enhancement relies on the general decay pattern of the room environment and not the specific temporal/spatial configuration of early reflections. Experiment 3 assessed the relationships between room-associated speech enhancement and single-reflection echo suppression by measuring echo thresholds for both a traditional click-based stimuli and with speech materials. Echo thresholds were found to be uncorrelated with the results of Experiment I. This suggests that early reflections have little impact on the de-reverberation aspect of speech enhancement, which is consistent with the results from Experiment II. A two-process hypothesis is proposed to account for the results of these experiments as well as previous research on this topic. Prior exposure to a speech pattern provided via carrier phrases is argued to elicit improved temporal processing of speech that results in speech enhancement. It is also argued that a process of de-reverberation effectively reduces the attenuation of temporal information in room environments.

Book excerpt: This report summarizes the effects upon speech intelligibility of both steady-state time-varying noise, particularly time-varying aircraft and traffic noises. Though no present measure adequately predicts this effect, the articulation index (AI) is recommended as the best available. In the classroom an AI of 0.4 is considered a minimum requirement for instruction and ideally, an AI of 0.7 or greater is recommended, especially under time-varying noise conditions. (Author).
