1. Bone-Anchored Hearing Implants: Surgical and Audiological Comparison of Different Surgical Techniques
Abstract Introduction The bone-anchored hearing implant system (BAHS) is an effective amplification system that transmits the sounds received by an external operating system to the inner ear by bypassing the middle ear placed in the temporal bone. Objective This study compares the results of patients who underwent bone-anchored hearing implant system (BAHS

4. Active Bone Conduction Prosthesis: BonebridgeTM
Introduction Bone conduction implants are indicated for patients with conductive and mixed hearing loss, as well as for patients with single-sided deafness (SSD). The transcutaneous technology avoids several complications of the percutaneous bone conduction implants including skin reaction, skin growth over the abutment, and wound infection. The Bonebridge

5. Benefício do sistema de frequência modulada em crianças usuárias de aparelhos de amplificação sonora individual e implante coclear / Benefit of the frequency modulation system for children users of individual sound amplification devices and cochlear implants
The child with sensorineural hearing loss presents more difficulty to understand speech in noise compared with children with normal hearing. Therefore, it is important to consider the use of resources, such as the frequency modulation (FM) system, which help users of hearing aids (HA) and cochlear implants (CI) in speech recognition in noise. OBJECTIVE: veri

6. Percepção da fala em crianças usuárias de implante coclear com duas estratégias de processamento do sinal do sistema HiResolution / Speech perception in children with cochlear implants with two sound processing strategy of the HiResolution system
Improvements in speech perception with cochlear implant (CI) over the years is related, among others factors, to the technological advance of the sound processing strategy. The purpose of the present study was to investigate speech perception performance in CI children, with two different Advanced Bionics sound processing strategy. Subjects were 11 prelingua

7. Uso de parâmetros multifractais no reconhecimento de locutor / Use of multifractal parameters for speaker recognition
Esta dissertação apresenta a implementação de um sistema de Reconhecimento Automático de Locutor (ASR). Este sistema emprega um novo parâmetro de características de locutor baseado no modelo multifractal "VVGM" (Variable Variance Gaussian Multiplier). A metodologia adotada para o desenvolvimento deste sistema foi formulada em duas etapas. Inicialmente

8. Efeitos do(s) letramento(s) na constituição social do sujeito: considerações fonoaudiológicas / Effects of literacy (ies) to the social constitution of the subject: speech therapy considerations
Introduction: This paper reflects on speech therapy, reading and writing, from relationships between literacy processes, social practices and discursive circulation of children in the process of sociocultural formation. Recent studies have defined literacy as a set of social practices that use writing (as a symbolic and technological system) in given context

9. A novel word boundary detector based on the teager energy operator for automatic speech recognition
This work is part of a major research project and contributes into the development of a speaker-independent speech recognition system for isolated words from a limited vocabulary. It proposes a novel spoken word boundary detection method named TEO-based method for Spoken Word Segmentation (TSWS). Based on the Teager Energy Operator (TEO), the TSWS is present

12. Text not informed by the author / Efeito de áudio em 3D na compreensibilidade de uma entre duas mensagens simultâneas em língua estrangeira: aplicação em grupos de controladores de tráfego aéreo experientes e novatos
This study aimed to verify whether the dichotic or spatialized (3D audio system) presentation of two simultaneous sentences in English facilitate the identification of a target information comparing to dihotic (nonspatialized) presentation. The subjects in this study were air traffic controllers having as L1 (mother tongue) Brazilian Portuguese, and were div
