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...
Background and purpose: We can examine the language abilities of a person through five parameters of speech quality including speech fluency, speech complexity, speech exactness, speech rate and lexical accessibility. These parameters are examined by the secondary parameters including mean length of utterance (MLÜ), mean length of five long utterances, mean number of verb in sentence, mean nu...
Although, speech recognition systems are widely used and their accuracies are continuously increased, there is a considerable performance gap between their accuracies and human recognition ability. This is partially due to high speaker variations in speech signal. Deep neural networks are among the best tools for acoustic modeling. Recently, using hybrid deep neural network and hidden Markov mo...
Abstract Speech databases are part of the concatenative text to speech synthesis systems. Phonetic quality of the databases plays a significant role in the naturalness of the synthesized speech. This paper introduces two syllable and diphone speech databases for Persian and investigates the way of their development and their specifications and their advantages to each other. ...
background: previous studies have shown that interaural-time-difference (itd) training can improve localization ability. surprisingly little is, however, known about localization training vis-à-vis speech perception in noise based on interaural time difference in the envelope (itd env). we sought to investigate the reliability of an itd env-based training program in speech-in-noise perception a...
speech emotion can add more information to speech in comparison to available textual information. however, it will also lead to some problems in speech recognition process. in a previous study, we depicted the substantial changes of speech parameters caused by speech emotion. therefore, in order to improve emotional speech recognition rate, in a first step, the effects of emotion on speech par...
