the present study provides an analysis of the correlation between acoustic properties, duration and pitch amplitude of speech associated with three basic emotions: anger, sadness and joy against neutrality as a reference, emotionally expressed by six persian speakers. rise/fall connection model (taylor, 1995) is used to analyze acoustic parameters and measure how an utterance is modulated when ...

Hidden Markov Model is a popular statisical method that is used in continious and discrete speech recognition. The probability density function of observation vectors in each state is estimated with discrete density or continious density modeling. The performance (in correct word recognition rate) of continious density is higher than discrete density HMM, but its computation complexity is very ...

A dialogue system is a software program that enables a user to interact with a computer using a natural language (Kang et al. 2014). Since an essential task of the dialogue system is to understand what the user says, it must be able to determine the user’s intention indicated in the user’s utterance. A speech-act is a linguistic action and implies the user’s intention. Therefore, the dialogue s...

PURPOSE To describe the linguistic performance of Brazilian Portuguese-speaking children with Down syndrome by analyzing their Mean Length Utterance; to compare their performance to that of children with Specific Language Impairment and Typical Development; and to verify whether children with Down syndrome present developmental language delay or disorder. METHOD Participants were 25 children ...

By treating utterances as points in the i-vector space, ivector/PLDA can achieve fast verification. However, this approach lacks the ability to cope with utterance-length variability. A method called uncertainty propagation (UP) that takes the uncertainty of i-vectors into account has been recently proposed to deal with this problem. However, the loading matrix for modeling utterance-length var...

Age-related reductions in pulmonary elastic recoil and respiratory muscle strength can affect how older adults generate subglottal pressure required for speech production. The present study examined agerelated changes in speech breathing by manipulating utterance length and loudness during a connected speech task (monologue). Twenty-three older adults and twenty-eight young adults produced a mo...
