Language equations, maximality and error-detection
We use some ‘natural’ language operations, such as shuffle (scattered insertion) and scattered deletion to model 9 noisy channels, that is, nondeterministic processes transforming words to words. In this spirit, we also introduce the operation of scattered substitution and derive the closure properties of the language families in the Chomsky 11 hierarchy under this operation. Moreover, we consi...
متن کاملPronunciation Error Detection for New Language Learners
Existing pronunciation error detection research assumes that second language learners’ speech is advanced enough that its segments are generally well articulated. However, learners just beginning their studies, especially when those studies are organized according to western, dialogue-driven pedagogies, are unlikely to abide by those assumptions. This paper presents an evaluation of pronunciati...
متن کاملFUZZY INTEGRO-DIFFERENTIAL EQUATIONS: DISCRETE SOLUTION AND ERROR ESTIMATION
This paper investigates existence and uniqueness results for the first order fuzzy integro-differential equations. Then numerical results and error bound based on the left rectangular quadrature rule, trapezoidal rule and a hybrid of them are obtained. Finally an example is given to illustrate the performance of the methods.
متن کاملLanguage Models for Contextual Error Detection and Correction
The problem of identifying and correcting confusibles, i.e. context-sensitive spelling errors, in text is typically tackled using specifically trained machine learning classifiers. For each different set of confusibles, a specific classifier is trained and tuned. In this research, we investigate a more generic approach to context-sensitive confusible correction. Instead of using specific classi...
متن کاملAutomatic pronunciation error detection and guidance for foreign language learning
We propose an e ective application of speech recognition to foreign language pronunciation learning. The objective of our system is to detect pronunciation errors and provide diagnostic feedback through speech processing and recognition methods. Automatic pronunciation error detection is used for two kinds of mispronunciation, that is mistake and linguistical inheritance. The correlation betwee...
