Available in PDF, EPUB and Kindle. Book excerpt: Para que un sistema de reconocimiento automático de habla (ASR) sea usado en un ambiente real, debe ser preciso y robusto. Un sistema de reconocimiento de habla robusto debe tratar con habla espontánea que típicamente contiene titubeos, pausas, correcciones, palabras fuera del vocabulario, ruidos provocados por el locutor y ruidos en el medio ambiente, entre otros. En esta tesis se hace un estudio sobre el problema del habla fuera del vocabulario, en un intento por mejorar el reconocimiento de voz y aumentar la robustez de los sistemas ASR. La estructura experimental de esta tesis es un sistema ASR de diálogo dirigido llamado CONMAT, instalado en la Universidad de las Américas-Puebla. CONMAT es un conmutador automático con el dominio de nombres de personas y nombres de lugares dentro de la universidad. La meta de esta tesis consiste en hacer que el reconocedor encuentre palabras clave (nombres de personas y nombres de lugares) en frases con habla fuera del vocabulario y a la vez rechace las frases que contienen únicamente habla fuera del vocabulario. Las técnicas aquí investigadas combinan identificación de palabras clave (word spotting) con niveles de confianza. Se experimentan varias estrategias para modelar habla fuera del vocabulario, incluyendo el uso de fonemas, sílabas y palabras completas. Además, las técnicas se experimentan con el uso de modelos de lenguaje estocásticos (bigrams), con el propósito de disminuir el costo computacional que presentan los modelos "filler" o modelos basura. Todos los experimentos realizados en esta tesis usan el reconocedor basado en segmentos SpeechWorks, y son evaluados conforme a desempeño y costo computacional. El desempeño de reconocimiento es dado por una figura de mérito (FOM) especialmente diseñada en esta tesis para medir el desempeño de sistemas de diálogo dirigido. El costo computacional reportado en cada experimento representa el tiempo de reconocimiento por cada segundo de habla. En esta tesis se usa un corpus de de.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: El objetivo principal de los sistemas de reconocimiento de voz es proveer una forma más natural de interacción humano-computadora. En la actualidad existen diversos laboratorios de investigación que han desarrollado distintos trabajos en el área de reconocimiento de voz. El objetivo principal de estas investigaciones es crear sistemas de reconocimiento del lenguaje hablado capaces de reconocer voz con las menores restricciones posibles. Uno de estos laboratorios es el Center for Spoken Language Understanding (CSLU) del Oregon Graduate Institute (OGI), el cual ha desarrollado un conjunto de herramientas llamada CSLU Toolkit, en el cual se cuenta con utilerías para la investigación, desarrollo y transferencia de tecnología de sistemas de reconocimiento de voz. Estas herramientas apoyan a varias actividades involucradas en la creación de sistemas de reconocimiento tales como: procesamiento de señales, colección de datos de voz, reconocimiento del lenguaje hablado y desarrollo de aplicaciones, entre otras El objetivo de esta investigación es diseñar e implementar un Sistema Tutor Animado para la enseñanza del lenguaje hablado en México usando el CSLU Toolkit. Para tal efecto es necesario entrenar un reconocedor de voces de niños, que es a quien va dirigido el proyecto. Dicho reconocedor será una primera versión que servirá de base para futuras investigaciones.

This book was released on 1905 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: RESUMEN El comportamiento de los sistemas actuales de reconocimiento del habla se degrada rápidamente en presencia de ruido de fondo cuando las etapas de entrenamiento y de test no pueden llevarse a cabo en las mismas condiciones ambientales. El propósito de esta tesis es el estudio y la aplicación al reconocimiento automático del habla en ambientes ruidosos de nuevas representaciones de la señal de voz que sean robustas por sí mismas al ruido y reflejen exactamente las diferencias fonéticas entre espectros de voz. De forma natural, la estrecha relación existente entre el tipo de representación de la señal y la medida de distancia idónea para confrontar los vectores de parámetros ha conducido también al estudio de distancias en esta tesis. Para la evaluación de las técnicas propuestas se ha utilizado un sistema de reconocimiento de palabras aisladas mediante modelos ocultos de Markov. El hecho de que el sistema sea de palabras aisladas permite prescindir de las implicaciones de los niveles de conocimiento superiores al acústico: sintáctico, semántico, pragmático ... Por otro lado, los modelos ocultos de Markov son los que en estos momentos proporcionan unas mejores prestaciones en todos los sistemas en desarrollo. La aportación fundamental de esta tesis es la introducción de la predicción lineal de la parte causal de la secuencia de autocorrelación de la señal de voz como una técnica de parametrización robusta del habla en presencia de ruido. Esta técnica está estrechamente relacionada con la representación SMC y con el uso de un sistema sobredeterminado de ecuaciones de Yule-Walker. Su uso en reconocimiento de habla ruidosa es muy interesante debido a su simplicidad, su eficiencia computacional y sus altas tasas de acierto, que superan ampliamente a las técnicas mencionadas y a la clásica predicción lineal sobre la señal en condiciones severas de ruido. A partir de un estudio comparativo de distintas técnicas en el caso de ruido blanco y ruido real, se han extraído.

Download or read book Teaching Tech Together written by Greg Wilson and published by CRC Press. This book was released on 2019-10-08 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hundreds of grassroots groups have sprung up around the world to teach programming, web design, robotics, and other skills outside traditional classrooms. These groups exist so that people don't have to learn these things on their own, but ironically, their founders and instructors are often teaching themselves how to teach. There's a better way. This book presents evidence-based practices that will help you create and deliver lessons that work and build a teaching community around them. Topics include the differences between different kinds of learners, diagnosing and correcting misunderstandings, teaching as a performance art, what motivates and demotivates adult learners, how to be a good ally, fostering a healthy community, getting the word out, and building alliances with like-minded groups. The book includes over a hundred exercises that can be done individually or in groups, over 350 references, and a glossary to help you navigate educational jargon.

Download or read book Handbook of Child Language Disorders written by Richard G. Schwartz and published by Psychology Press. This book was released on 2010-10-18 with total page 1140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Child Language Disorders provides an in-depth, comprehensive, and state-of-the-art review of current research concerning the nature, assessment, and remediation of language disorders in children. The book includes chapters focusing on specific groups of childhood disorders (SLI, autism, genetic syndromes, dyslexia, hearing impairment); the linguistic, perceptual, genetic, neurobiological, and cognitive bases of these disorders; and the context of language disorders (bilingual, across dialects, and across languages). To examine the nature of deficits, their assessment and remediation across populations, chapters address the main components of language (morphology, syntax, semantics, and pragmatics) and related areas (processing, memory, attention, executive function such as reading and writing). Finally, even though there is extensive information regarding research and clinical methods in each chapter, there are individual chapters that focus directly on research methods. This Handbook is a comprehensive reference source for clinicians and researchers and can be used as a textbook for undergraduate, masters, and doctoral students in speech-language pathology, developmental psychology, special education, disabilities studies, neuropsychology and in other fields interested in children's language disorders.
