Validating Di erent 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 کاملMultiple viewpoints as an approach to digital library interfaces
A viewpoint is a representational scheme on some collection of data objects, together with a mechanism for accessing this content. A multiple viewpoint system allows a searcher to pose queries in one viewpoint and then change to another viewpoint while retaining a sense of context, taking advantage of the improvement in retrieval results given by using di erent relevance judgements and di erent...
متن کاملDevelopment of a French speech recognizer using a hybrid HMM/MLP system
In this paper we describe the development of a French speech recognizer, and the experiments we carried out on our hybrid HMM/ANN system which combines Arti cial Neural Networks (ANN) and Hidden Markov Models (HMMs). A phone recognition experiment with our baseline system achieved a phone accuracy of about 75% which is very similar to the best results reported in the literature [1]. Preliminary...
متن کاملExperiments towards a Multi-language LVCSR Interface
This paper describes experiments towards a multilanguage human-computer speech interface. Our interface is designed for large vocabulary continuous speech input. For this purpose a multilingual dictation database has been collected under GlobalPhone, which is a project at the Interactive Systems Labs. This project investigates LVCSR systems in 15 languages of the world, namely Arabic, Chinese, ...
