One of the interesting topics on multimedia domain is concerned with empowering computer in order to speech production. Speech synthesis is granting human abilities to the computer for speech production. Data-based approach and process-based approach are the two main approaches on speech synthesis. Each approach has its varied challenges. Unit-selection speech synthesis and statistical parametr...
OBJECTIVE This study aimed to evaluate the long-term speech perception and speech intelligibility of congenitally and prelingually deaf children after cochlear implantation. It was a longitudinal study following 63 congenitally or prelingually deaf children up to 5 years after implantation. They each received a nucleus multichannel cochlear implant before they were 10 years old. METHODS Perce...
Oronasal region, as an important organ of taste and smell, being respected for its impact on the resonace, which is crucial for any normal speech production. Different congenital, acquired and/or developmentalpdefect, may not only have impacts on the quality of respiration, phonation, resonance, also on the process of a normal speech. This article will enable readers to have more focus in such ...
We retrospectively studied outcome of a sample of 36 congenitally deaf children who were fitted with either a conventional hearing aid (HA, N = 14) or a cochlear implant (CI, N = 22), and who received many years of audio-phonatory training by our multi-disciplinary team. In order to rate speech discrimination perception, we developed a new metric of speech discrimination performance based on se...
In this paper it is shown experimentally that a new blind signal separation method in the frequency domain improves significantly the speaker signal to interference ratio (SIR) and the phoneme recognition score of a continuous speech, speaker-independent acoustic decoder in a two-simultaneousspeaker environment. The implemented two-sensor separation method is based on evolutionary minimization ...
Background & Aim: When inner ear is disturbed, both hearing sensitivity and selective property decrease. Early rehabilitation for proper progression of speech and language appropriate to age is mandatory. Several studies were performed to compare factors that affect the results of cochlear implantations to select the best candidates on the basis of different criteria. This study was underta...
Abstract: We consider a new scenario in blind speech separation problem in which the number and the features of active sources change with time in opposite to the previous methods in which all sources are active all the time. Accordingly, we propose the new DESICA algorithm for source separation which is a compound of the ICA and DESPRIT algorithms. In this algorithm, using the ICA, the separat...
Background and purpose: Speech sound disorders are the most common speech disorders in children which are associated with other problems and can lead to social problems, attention deficit and academic skills challenges. The aim of this study was to investigate articulation characteristics, phonological awareness and language skills in children with speech sound disorders. Materials and metho...
