چکیده

This article presents the results of grapheme-based speech recognition for eight languages. The need for this approach arises in situation of low resource languages, where obtaining a pronunciation dictionary is timeand cost-consuming or impossible. In such scenarios, usage of grapheme dictionaries is the most simplest and straight-forward. The paper describes the process of automatic generation of pronunciation dictionaries with emphasis on the expansion of numbers. Experiments on GlobalPhone database show that grapheme-based systems have results comparable to the phonemebased ones, especially for phonetic languages.

Comparison of Slovak and Czech speech recognition based on grapheme and phoneme acoustic models

Grapheme based mono-, crossand bilingual speech recognition of Czech and Slovak is presented in the paper. The training and testing procedures follow the MASPER initiative that was formed as a part of the COST 278 Action. All experiments were performed using Czech and Slovak SpeechDat-E databases. Grapheme-based models gave equivalent recognition performance compared to phoneme-based models in ...

Grapheme based speech recognition

Large vocabulary speech recognition systems traditionally represent words in terms of subword units, usually phonemes. This paper investigates the potential of graphemes acting as subunits. In order to develop context dependent grapheme based speech recognizers several decision tree based clustering procedures are performed and compared to each other. Grapheme based speech recognizers in three ...

Category-based phoneme-to-grapheme transliteration

Grapheme-based speech recognition systems are faster to develop but typically do not reach the same level of performance as phoneme-based systems. In this paper we introduce a technique for improving the performance of standard grapheme-based systems. We find that by handling a relatively small number of irregular words through phoneme-to-grapheme (P2G) transliteration – transforming the origin...

Conversion from phoneme based to grapheme based acoustic models for speech recognition

This paper focuses on acoustic modeling in speech recognition. A novel approach how to build grapheme based acoustic models with conversion from existing phoneme based acoustic models is proposed. The grapheme based acoustic models are created as weighted sum from monophone acoustic models. The influence of particular monophone is determined with the phoneme to grapheme confusion matrix. Furthe...

Thai Grapheme-Based Speech Recognition

In this paper we present the results for building a grapheme-based speech recognition system for Thai. We experiment with different settings for the initial context independent system, different number of acoustic models and different contexts for the speech unit. In addition, we investigate the potential of an enhanced tree clustering method as a way of sharing parameters across models. We com...
