Validating different flexible vocabulary approaches on the Swiss French Polyphone and Polyvar databases

چکیده
In this paper, we attempt to validate the exible vocabulary approach for speaker independent isolated word and connected words recognition. We compare the performance of classical whole word HMMs against di erent sets of subword units. For this purpose, we model phonemes, diphones and words of the (Swiss) French language. The recognition rates obtained with phoneme models are monitored as we increase the amount of training data. The results of the described experiments validate the exible vocabulary approach and show advantages and disadvantages of both propposed subword units against common whole word HMMs.

متن کاملThe Effect of Semantic Mapping as a Vocabulary Instruction Technique on EFL Learners with Different Perceptual Learning Styles
Traditional and modern vocabulary instruction techniques have been introduced in the past few decades to improve the learners’ performance in reading comprehension. Semantic mapping, which entails drawing learners’ attention to the interrelationships among lexical items through graphic organizers, is claimed to enhance vocabulary learning significantly. However, whether this technique suits all...
متن کاملHealth Priorities in French-Speaking Swiss Cantons
In Switzerland, the federal authorities, the cantons, and the communes share the responsibility of healthcare, disease prevention and health promotion policies. Yet, the cantons are in most health matters independent in their decisions, thus defining as a matter of fact their own health priorities. We examined and analysed the content of the disease prevention and health promotion plans elabora...
