An error-corrective language-model adaptation for automatic speech recognition
نویسندگان
چکیده
We present a new language model adaptation framework integrated with error handling method to improve accuracy of speech recognition and performance of spoken language applications. The proposed error corrective language model adaptation approach exploits domain-specific language variations and recognition environment characteristics to provide robustness and adaptability for a spoken language system. We demonstrate some experiments of spoken dialogue tasks and empirical results which show an improvement of the accuracy for both speech recognition and spoken language understanding.

متن کاملGrammatical Error Detection for Corrective Feedback Provision in Oral Conversations
The demand for computer-assisted language learning systems that can provide corrective feedback on language learners’ speaking has increased. However, it is not a trivial task to detect grammatical errors in oral conversations because of the unavoidable errors of automatic speech recognition systems. To provide corrective feedback, a novel method to detect grammatical errors in speaking perform...
متن کاملDynamic Language Model Adaptation Using Latent Topical Information and Automatic Transcripts
This paper investigates dynamic language model adaptation for Mandarin broadcast news recognition. A topical mixture model was presented to dynamically explore the long−span latent topical information for language model adaptation. The underlying characteristics and different kinds of model structures were extensively investigated, while their performance was verified by comparison with the con...
متن کاملUnsupervised language model adaptation based on topic and role information in multiparty meetings
We continue our previous work on the modeling of topic and role information from multiparty meetings using a hierarchical Dirichlet process (HDP), in the context of language model adaptation. In this paper we focus on three problems: 1) an empirical analysis of the HDP as a nonparametric topic model; 2) the mismatch problem of vocabularies of the baseline n-gram model and the HDP; and 3) an aut...
