Speech Enhancement With Inventory Style Speech Resynthesis

We present a new method for the enhancement of speech. The method is designed for scenarios in which targeted speaker enrollment as well as system training within the typical noise environment are feasible. The proposed procedure is fundamentally different from most conventional and state-of-the-art denoising approaches. Instead of filtering a distorted signal we are resynthesizing a new “clean” signal based on its likely characteristics. These characteristics are estimated from the distorted signal. A successful implementation of the proposed method is presented. Experiments were performed in a scenario with roughly one hour of clean speech training data. Our results show that the proposed method compares very favorably to other state-of-the-art systems in both objective and subjective speech quality assessments. Potential applications for the proposed method include jet cockpit communication systems and offline methods for the restoration of audio recordings.

Effects Of Perceived Financial Accessibility Of Colleges And Universities On Studentsâ¿ Assesment Of Institutional Desirability

This study focused on the effects of socioeconomic exclusivity indicators on college students¿ attitudes toward a hypothetical private liberal arts university. Students enrolled in two undergraduate courses in Education at an elite private liberal arts university in the northeast were randomly presented with one of three versions of an admissions brochure describing a fictitious university. The three versions of the brochure varied in their portrayals of the institution¿s financial exclusivity, ranging from high exclusivity to low exclusivity. Each student was asked to review the brochure and respond to a questionnaire, containing items pertaining to the overall desirability of the institution, as well as its student culture, academic program, campus traditions, and alumni network. Based on Thorstein Veblen¿s theory of the leisure class and Pierre Bourdieu¿s theory of social reproduction, it was hypothesized that students would judge the institution most favorably in all areas under the high exclusivity condition and least favorably under the low exclusivity condition. It was further hypothesized that differences in students¿ ratings of institutional desirability would be mediated by their own financial aid statuses. Results of a two-way multivariate analysis of variance (MANOVA) revealed significant (p < .05) interactive effects of institutional exclusivity and student aid status on the perceived desirability of the academic program and campus traditions of the institution. While recipients of need-based financial aid tended to rate more socioeconomically exclusive institutions more favorably on these two variables, those who were not receiving need-based financial aid tended to rate such institutions less favorably. Implications of the findings for student affairs practice are discussed and recommendations for further research are presented.

Training in Mental Health: Evaluation of the Telephone Conference Network

The Telephone Conference Network, sponsored by The Pennsylvania State University's Coordinating Council for Health Care, is designed as a cost-effective format for providing inservice training in geriatric mental health for individuals who serve the elderly. Institutions which subscribe to the Telephone Conference Network are equipped with a conference speaker and telephone hook-up providing a two-way line of communication, and may choose from a variety of inservice programs. Mailed evaluations were completed by participants (N=73) in the "Skills to Manage Moods" program, a series of four 1-hour sessions designed to teach participants the skills needed to help patients cope with depression and to deliver the program to others. The majority of respondents reported high levels of satisfaction with the Telephone Conference Network system and the specific program in which they participated. Although 85 percent reported that they would be able to use the skills learned in the program on the job, 50 percent reported that they would not be interested in teaching these skills to others. The convenience and efficiency of the Telephone Conference Network were the most frequently mentioned strengths of the system, while the physical facilities and the program delivery format adopted by the individual institutions were the most frequently mentioned weaknesses. These data suggested several recommendations for Network subscribers and for professionals offering telephone conference programs, including ensuring optimal class enrollment and adequate physical facilities, and participant involvement in program implementation.
