For example, we know very little about potential errors young L2 learners make when they produce yes/no questions–an area that is crucial in order to provide useful feedback in different learning environments, including computer-based applications. This paper reports on an exploratory study conducted with Can you guess who I am? , an interactive, spoken-dialogue-based speaking activity that allows young English learners to practice yes/no questions. After intro-ducing the SDS-based speaking activity, we present the ﬁndings from a systematic investigation of the output produced by 27 young English learners in Germany (ages 9-11) who engaged with the activity. A particular focus in the analysis was placed on the types of yes/no questions elicited and the types of errors made by the young learners. The ﬁndings provide further empirical support for a six-stage framework for the development of question formation in L2 learners [14]. Moreover, they offer insights into the types of errors young EFL learners make in forming polar interrogatives such as systematic confusion with regard to the auxiliaries “to be” and “to do”. The ﬁndings are discussed in terms of (a) how they contribute to a more comprehensive understanding of young learner’s speech and (b) how they will be used to inform further development of more targeted feedback options that can be implemented into the SDS-based speaking activity in order to harness its full potential for L2 learning. English—an underexplored area in young L2 learner research.","PeriodicalId":91973,"journal":{"name":"The ...

This papers presents a new application for the existing diarization systems and investigates the language environment of young children using a turn taking strategy employing an i-vector based baseline that captures adult-to-child or child-tochild conversational turns across different classrooms in a child care center. Detecting speaker turns is necessary before more in depth subsequent analysis of audio such as word count, speech recognition, and keyword spotting which can contribute to the design of future learning spaces specifically designed for typically developing children, or those at-risk with communication limitations. Experimental results using naturalistic childteacher classroom settings indicate the proposed rapid childadult speech turn taking scheme is highly effective under noisy classroom conditions and results in 27.3% relative error rate reduction compared to the baseline results produced by the LIUM diarization toolkit.","PeriodicalId":91973,"journal":{"name":"The ...

This lack of eye contact limits their ability to read social and emotional cues exhibited through facial expressions resulting in a corresponding decrease in social engagement. The use of interactive virtual environments (VEs) as a therapeutic protocol is a growing field of study. In recent studies, individuals with ASD were placed in VEs and engaged with avatars controlled by a human in the background, resulting in improvements in eye contact and engagement for some subjects. This paper is the first in a series of experiments exploring the potential of virtual avatars controlled through software agency, rather than human control, as a therapeutic tool for ASD. This paper examines if a subject could learn to make eye contact with an avatar and consequently recognize and respond to emotional cues expressed by the avatar. Results indicate that children with ASD can learn to recognize the emotional cues of the virtual avatar, and that their reactions to the avatar’s needs as well as their eye contact with the avatar improved over the course of the VE experiment. This study sets the stage for future exploration into therapeutic use of agent-based virtual avatars, including transference of emotional cues from avatars to humans in the real world.","PeriodicalId":91973,"journal":{"name":"The ...

However, this amount of training data is not always available for some applications. In this paper, we investigate how to use an adult speech corpus to improve DNN-based automatic speech recognition for non-native children's speech. Although there are many acoustic and linguistic mismatches between the speech of adults and children, adult speech can still be used to boost the performance of a speech recognizer for children using acoustic modeling techniques based on the DNN framework. The experimental results show that the best recognition performance can be achieved by combining children's training data with adult training data of approximately the same size and initializing the DNN with the weights obtained by pre-training using the full training set of the adult corpus. This system can outperform the baseline system trained on only children's speech with an overall relative WER reduction of 11.9%. Among the three speaking tasks studied, the picture narration task shows the largest gain with a WER reduction from 24.6 % to 20.1%.","PeriodicalId":91973,"journal":{"name":"The ...

Recognition results are presented for three corpora of children’s speech, two comprising recordings of American English spoken by ﬁve-to nine-year-olds and one comprising recordings of British English speech from children aged ﬁve and six. The results are compared with adult reference confusion matrices based on TIMIT for the ﬁrst two experiments and with confusion matrices for British adults and children with good speech for the third. They appear to be inﬂuenced by three factors: (i) confusions that are predictable from phonological factors associated with language acquisition also arise from acoustic confusability (e.g. /k/ → /t/ ) , (ii) the frequency of the phonological errors is expected to decrease with increasing age, and (iii) an accurate recogniser is more likely to detect a phonological error when it occurs than a less accurate one. Overall the percentage of errors attributable to phonological processes remains approximately constant in each experiment. However, the proportion of these errors that differ signiﬁcantly from reference patterns increases with recognition accuracy and is greater for children who are judged to have poor speech.","PeriodicalId":91973,"journal":{"name":"The ...
