Book Description
This report presents the results of a large study of new objective measures for speech quality. The study defined a figure-of-merit for a particular objective quality measure using correlation analysis between a data base of subjective speech quality measures and a data base of objective speech quality measures. Both data bases were derived from approximately twenty hours of coded and distorted speech. The subjective test used was the Diagnostic Acceptability Measure (DAM) developed at the Dynastat Corp. The study concentrated on three classes of objective measures: those based on a model of the ear, those based on parametric subjective quality estimate, and those based on preclassified distortion sets. All three classes of objective measures performed well, but the best results were obtained for the class of parametric measures. Keywords include: Objective testing, Subjective testing, Voice communication, Speech communications, Coding, and Speech coding.

Book Description
It is becoming crucial to accurately estimate and monitor speech quality in various ambient environments to guarantee high quality speech communication. This practical hands-on book shows speech intelligibility measurement methods so that the readers can start measuring or estimating speech intelligibility of their own system. The book also introduces subjective and objective speech quality measures, and describes in detail speech intelligibility measurement methods. It introduces a diagnostic rhyme test which uses rhyming word-pairs, and includes: An investigation into the effect of word familiarity on speech intelligibility. Speech intelligibility measurement of localized speech in virtual 3-D acoustic space using the rhyme test. Estimation of speech intelligibility using objective measures, including the ITU standard PESQ measures, and automatic speech recognizers.

Book Description
Speech Processing and Soft Computing includes coverage of synergy between speech technology and bio-inspired soft computing methods. Through practical cases, the author explores, dissects and examines how soft computing may complement conventional techniques in speech enhancement and speech recognition in order to provide robust systems. The material is especially useful to graduate students and experienced researchers who are interested in expanding their horizons and investigating new research directions through review of the theoretical and practical settings of soft computing methods in very recent speech applications.

Book Description
Speech quality measurement--in terms of user acceptability--is considered from 3 points of view: subjective testing, objective testing, and communicability testing. It is assumed that good intelligibility is always present. Subjective testing is considered from the perspective of isopreference, relative preference, and absolute-preference, with isometric and parametric test methodologies, with the results of PARM and QUART as a basis. It is felt that the best approach for future subjective testing will be a parametric approach using representative male and female talkers to cover the expected range of pitch. Objective testing is considered as a possible alternative to subjective testing. A two part experimental study of the relationship between a number of objective measures and the subjective acceptability measures available from the PARM study is described. In the communicability test, the user is expected to perform on the data some cognitive task which is measurable. The rationale is that the user will be better able to perform if the quality is high, than if his cognitive resource, assumed fixed, is saturated due to poorer quality transmission.

Book Description
The U.S. Social Security Administration (SSA) provides disability benefits through the Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) programs. To receive SSDI or SSI disability benefits, an individual must meet the statutory definition of disability, which is "the inability to engage in any substantial gainful activity [SGA] by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months." SSA uses a five-step sequential process to determine whether an adult applicant meets this definition. Functional Assessment for Adults with Disabilities examines ways to collect information about an individual's physical and mental (cognitive and noncognitive) functional abilities relevant to work requirements. This report discusses the types of information that support findings of limitations in functional abilities relevant to work requirements, and provides findings and conclusions regarding the collection of information and assessment of functional abilities relevant to work requirements.
