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...

a parallel hybrid system of hmm and gmm modeling techniques was implemented and used in a telephony speaker verification and identification system. spectral subtraction and weighted projection measure were used to render this system more robust against additional noise. cepstral mean subtraction method was also applied for the compensation of convolution noise due to transmission channel degrad...

Previous ERP studies have often reported two ERP components-LAN and P600-in response to subject-verb (S-V) agreement violations (e.g., the boys (*) runs). However, the latency, amplitude and scalp distribution of these components have been shown to vary depending on various experiment-related factors. One factor that has not received attention is the extent to which the relative perceptual sali...

background: developmental sentence scoring (dss) was developed as a numerical measurement and a clinical method based on the morphosyntactic acquisition in the english language. the aim of this study was to develop a new numerical tool similar to dss to assess the morphosyntactic abilities in persian-speaking children.   methods:  in this cross-sectional and comparative study, the language samp...

This research was conducted when the children were 3 years and 6 months old. The child’s nams is Muhammad Habibie. son of Mr. Azwal Effendi Mrs. Rostiana. study to test children's speaking ability in 1, 2, 3, 4 5 words. uses average utterance length (MLU) survey method. data collection technique done by recording spoken words using a mobile phone. use tap method, results are written analyzed. A...

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...

Feature statistics normalization techniques have been shown to be very successful in improving the noise robustness of a speech recognition system. In this paper, we propose an associative scheme in order to obtain a more accurate estimate of the statistical information in these techniques. By properly integrating codebook and utterance knowledge, the resulting associative cepstral mean subtrac...

The validity of the Fundación MacArthur Inventario del Desarrollo de Habilidades Comunicativas: Palabras y Enunciados (IDHC:PE) was examined with twenty 20- and nineteen 28-month-old, typically developing, monolingual, Spanish-speaking children living in Mexico. One measure of vocabulary (number of words) and two measures of grammar (mean of the three longest utterances and grammatical complexi...
