13. Processamento auditivo (central): o discurso de um grupo de fonoaudiólogos / (Central) auditory processing: the speech of a group of speech-language pathologist/audilogist
The (central) auditory processing is the efficiency and effectiveness with which the central auditory nervous system processes the sounds, from its reception to its interpretation. Perceptual, cognitive and linguistic mechanisms have an influence on recognizing, decoding and interpreting the information heard. Because it consists of a cerebral activity, it i

14. Conjunto dos números irracionais: a trajetória de um conteúdo não incorporado às práticas escolares
The main objective of this work is to investigate the difficulties that appeared along the history for the development of the mathematical content irrational numbers and which are the approaches present in the text books. The subject irrational numbers is considered important in the basic education of Mathematics and it comes for the students, in the text bo

15. UM SISTEMA DE GERAÇÃO DE EXPRESSÕES FACIAIS DINÂMICAS EM ANIMAÇÕES FACIAIS 3D COM PROCESSAMENTO DE FALA / A SYSTEM FOR GENERATING DYNAMIC FACIAL EXPRESSIONS IN 3D FACIAL ANIMATION WITH SPEECH PROCESSING
Esta tese apresenta um sistema para geração de expressões faciais dinâmicas sincronizadas com a fala em uma face realista tridimensional. Entende-se por expressões faciais dinâmicas aquelas que variam ao longo do tempo e que semanticamente estão relacionadas às emoções, à fala e a fenômenos afetivos que podem modificar o comportamento de uma face

16. Errors in nonword repetition: bridging short- and long-term memory
According to the working memory model, the phonological loop is the component of working memory specialized in processing and manipulating limited amounts of speech-based information. The Children's Test of Nonword Repetition (CNRep) is a suitable measure of phonological short-term memory for English-speaking children, which was validated by the Brazilian Ch

17. Conversion grapheme-phone for a system of recognition of voice with support the great vocabularies for the Brazilian Portuguese / Conversão grafema-fone para um sistema de reconhecimento de voz com suporte a grandes vocabulários para o português brasileiro
Speech processing has become a data-driven technology. Hence, the success of research in this area is linked to the existence of public corpora and associated resources, as a phonetic dictionary. In contrast to other languages such as English, one cannot find, in public domain, a Large Vocabulary Continuos Speech Recognition (LVCSR) System for Brazilian Port

18. A new method for determining the number of gaussians in hidden Markov models for continuos speech recognition systems / Metodo para a determinação do numero de gaussianas em modelos ocultos de Markov para sistemas de reconhecimento de fala continua
Nowadays, HMM-based speech recognition systems are used in many real time processing applications, from cell phones to auto mobile automation. In this context, one important aspect to be considered is the HMM complexity, which directly determines the system computational load. So, in order to make the system feasible for practical purposes, it is interesting

19. INTERPOLAÇÃO MODIFICADA DE LSFNULLS / MODIFIED INTERPOLATION OF LSFNULLS
Os novos serviços de telecomunicações têm impulsionado o desenvolvimento de melhorias nos algoritmos de codificação de voz, devido à necessidade de se melhorar a qualidade da voz codificada, utilizando a menor taxa de transmissão possível. Esta dissertação analisa e propõem melhorias em um método para o ajuste de parâmetros LSFs de modo a torn�

20. Algoritmos OPWI e LDM-GA para sistemas de conversão texto-fala de alta qualidade empregando a tecnologia SCAUS / Algorithm OPWI and LDM-GA for high quality text-to-speech synthesis based on automatic unit selection
This Thesis presents two new algorithms for Unit Selection Based Text-to-Speech systems (USBTTS). The first algorithm is the OPWI (Optimized Prototype Waveform Interpolation), which was designed to be used as a Back-End module for USB-TTS. The second algorithm is the LDM-GA (Linguistic Data Mining Using Genetic AIgorithm), which was designed to minimize trai

22. Aspectos da avaliação audiológica periférica e central na neuropatia auditiva/dessincronia auditiva: um estudo de caso / Aspects of audiologic peripherical and central evaluation on auditory neuropathy/auditory dys-synchrony: a case study
Objective: The goal of this research was to describe the peripherical and central audiological findings of a child with auditory neuropathy/auditory dys-synchrony. Methods: It was performed an audiological evaluation, eletrophysiological and behavioral, with tests that appraise the peripherical and central auditory system. Results: The result found in audiom

23. Sistema de conversão texto-fala para a lingua portuguesa utilizando a abordagem de sintese por regras
This work contains a description of the text-to-speech conversion system for the Portuguese of Brazil developed at the Signal Processing Laboratory of the Electrical and Computer Engineering School of Unicamp. The system receives as input a generic text in Portuguese and produces as output the corresponding speech signal. The text-to-speech conversion proces

24. Um ambiente para a analise superficial de linguas baseado em automatos finitos
Syntactic analysis is an important component of most natural language processing systems. Typically parsers were implemented using techniques derived from Context Free Grammars. The increasing need for efficient systems was one of the reasons to search for new approaches to syntactic analysis. Some natural language applications do not need complete parsing o
