Large vocabulary automatic speech recognition might assist hearing impaired telephone users by displaying a transcription of the incoming side of the conversation, but the system would have to achieve su cient accuracy on conversationalstyle, telephone-bandwidth speech. We describe our development work toward such a system. This work comprised three phases: Experiments with clean data ltered to...

This study examined the relationships between L2 learners' anxiety, self-confidence and oral performance. The participants were 132 Korean college students who enrolled the English conversation classes in 2004. Questionnaires related to anxiety and self-confidence were given to the students and their oral performances were assessed in terms of IATEFL's criteria. Factor analysis indicated that c...

Two main features of vocabulary knowledge, namely breadth and depth, have a fundamental role in vocabulary research. This research aimed to study the relationship between vocabulary knowledge and reading comprehension, and to investigate which feature of vocabulary knowledge, breadth or depth, had better impact on identifying reading comprehension performance. Therefore, three language tests we...

this study has examined the effect of semantic mapping on learning vocabulary across genders. the researchers selected 120 intermediate students after the administration of a standard proficiency test. a vocabulary test was also used to measure the students’ vocabulary knowledge. the experimental group received semantic mapping in the pre-reading stage, butthe control group did not receive this...

One of the key tasks for analyzing conversational data is segmenting it into coherent topic segments. However, most models of topic segmentation ignore the social aspect of conversations, focusing only on the words used. We introduce a hierarchical Bayesian nonparametric model, Speaker Identity for Topic Segmentation (SITS), that discovers (1) the topics used in a conversation, (2) how these to...

Intermediate English Speaking expected the students to be able use vocabulary that is relevant material and fully participated in casual conversation including describing an object. In 21st century, critical thinking, problem-solving, communication, collaboration or 4Cs skills should mastered by students. So, lecturer uses Project Based Learning as method suggested government, together with Tik...

Present limits of speech recognition and understandi¢,g in the context of free spoken language (alttumgh with a limited vocabulary) have perverse effects on the flow of the dialogue with a system. Typically a non robtt~'t dialogue manager will fail to face with these limits and conversations will often be a failure. This paper presents some possibilities of a structural approach for handling co...

A research on the analysis of human/human conversations in a call centre is described. The purpose of the research is to provide short reports of each conversation with information useful for monitoring the call centre efficiency. Data from real users discussing over the telephone with agents are processed by an automatic speech recognition (ASR) system. Reports are grouped into classes by the ...
