In this paper, a new approach for age estimation from speech signals based on i-vectors is proposed. In this method, each utterance is modeled by its corresponding i-vector. Then, a Within-Class Covariance Normalization technique is used for session variability compensation. Finally, a least squares support vector regression (LSSVR) is applied to estimate the age of speakers. The proposed metho...

objectives: the spontaneous language sample analysis is an important part of the language assessment protocol. language samples give us useful information about how children use language in the natural situations of daily life. the purpose of this study was to compare conversation, freeplay, and narrative speech in aspects of mean length of utterance (mlu), type-token ratio (ttr), and the numbe...

This paper investigates the combination of vocal tract length normalisation and speaker adaptation in connected digit recognition. In particular, we focus on performing this task under a continuously varying car noise environment. Continuous supervised speaker and environment adaptation is carried out on the test data according to the Bayesian framework. The paper also evaluates various approac...

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...

Objectives: Parental linguistic input is one of the most important factors in early language environment young children. This study aimed to investigate characteristics parental toddlers with cochlear implants (CIs), aged 12-36 months, compared those typical hearing (TH); and explore relationships between variables development each group. Methods: 14 CIs 18 TH was examined during a 20 minute fr...
