Purpose: To study comparatively the speech recognition skills in quiet and noise background situation in children with cochlear implants using two different speech processors. Methods: It was evaluated 26 children with cochlear implant device Nucleus 24M or 24K, Cochlear Corporation, divided in two groups according to the speech processor used. The Group 1 consisted of 16 children who used the ...


 Humans use language to give and receive information through various types of media, including audio visual media. In speech events, sentences show the intent purpose communicating. The words spoken by a speaker can indicate or speakers so that other people understand them more easily. every communication process, events acts occur. Speech are strongly influenced context situation. This i...

In most approaches based on computational auditory scene analysis (CASA), the ideal binary mask (IBM) is often used for noise reduction. However, it is almost impossible to obtain the IBM result. The error in IBM estimation may greatly violate smooth evolution nature of speech because of the energy absence in many speech-dominated time-frequency (TF) units. To reduce the error, the ideal ratio ...

Accurate recognition of speech in noisy environment is still an obstacle for wider application of speech recognition technology. Noise reduction, which is aimed at cleaning the corrupted testing signal to match the ideal training conditions, remain to be an effective approach to improving the accuracy of speech recognition in noisy environment. This paper introduces a new algorithm of noise red...

The shortage of pediatricians has been identified as one of the largest social problems in Japan. This study aimed to compare the assumed ideal nighttime working conditions of pediatric hospitalists in Japan with the actual current situation. By using available data on the age-related numbers of pediatricians in Japan, we described the ideal working conditions for pediatric hospitalists in Japa...

OBJECTIVE The purpose of this study was to determine the maximum benefit provided by a time-frequency gain-manipulation algorithm for noise-reduction (NR) based on an ideal detector of speech energy. The amount of detected energy necessary to show benefit using this type of NR algorithm was examined, as well as the necessary speed and frequency resolution of the gain manipulation. DESIGN NR w...

To assess the effects of physiological feedback during actual exposure to a feared situation and during a subsequent exposure, 60 speech-anxious subjects were exposed to one of five false feedback conditions during the second of three consecutive speeches: heart rate decreasing, no change in heart rate, heart rate increasing, and two control procedures. No anxiety differences were found among t...
