We describe a pronunciation instruction system that dynamically generates CG animations to express the pronunciation from speech based on articulatory features. Specifically, the system displays the results of phoneme recognition and animation of the pronunciation movements of both the learner and teacher from their speech in order to show in what way the learner’s pronunciation is wrong. Learn...

In the past, fundamental linguistic research was typically conducted on small data sets that were handcrafted for the specific research at hand. However, from the eighties onwards, many large spoken language corpora have become available. This study investigates the usefulness of large multi-purpose spoken language corpora for fundamental linguistic research. A research task was designed in whi...

When reading texts of different but closely related languages, intelligibility is determined among others by the number of words which are cognates of words in the reader’s language, and orthographic differences. Orthographic differences partly reflect pronunciation differences and therefore are partly a linguistic level. Dialectometric studies in particular showed that different linguistic lev...

The large pronunciation variability of words in conversational speech is one of the major causes of low accuracy for automatic speech recognition (ASR). Many pronunciation modeling approaches have been developed to address this problem. Some explicitly manipulate the pronunciation dictionary as well as the set of the units used to define the pronunciations of words. Others model the pronunciati...

In this paper, three different approaches to pronunciation modeling are investigated. Two existing pronunciation modeling approaches, namely the pronunciation dictionary and n-best rescoring approach are modified to work with little amount of non-native speech. We also propose a speaker clustering approach, which capable of grouping the speakers based on their pronunciation habits. Given some s...

This paper presents an error prevention approach in the development of a Computer Assisted Pronunciation Training System (CAPT System) for teaching American English pronunciation to adult Mexican Spanish speakers developed for the case of vowels. Prior knowledge of the learner’s typical articulatory and auditory perception errors enhances the effectiveness of training. It enables to organize th...
