Likelihood Combination and Recog the Decoding of Non-native Speech

چکیده
In this paper we report on the combination of multilingual Hidden Markov Models for the recognition of non-native speech. Using a digit recognition task as an example, we first demonstrate the benefits of bilingual acoustic models that incorporate training data from both the target language and the speakers’ native language, and then compare two different recognizer combination methods, namely voting on recognition output (ROVER) and frame based, time synchronous likelihood combination. Finally, we demonstrate the usefulness of the proposed methods for speakers whose native language is not in the training data.

متن کاملSpeech-like Pragmatic Markers in Argumentative Essays Written by Iranian EFL Students and Native English Speaking Students
In this study, the use of speech-like pragmatic markers in Iranian EFL students’ academic writing was investigated. Speech-like pragmatic markers, such as I think, well, I guess, actually, anyway, anyhow, etc. are linguistic components that are more specific to conversation than writing, and writers may wrongly include them in their academic writing. To examine the students’ use of speech-like ...
