Automatic modeling of pronunciation variations
نویسنده
چکیده
We report on an automatic method for discovering an appropriate model topology for each context-dependent phoneme, allowing for such phenomena as reduced pronunciations and substituted phonemes. The method leads to a reduction in the word error rate on both the Wall Street Journal and Broadcast News databases.

Pronunciation lexicon adaptation for TTS voice building
This paper describes reducing phone label errors in TTS voice building by means of modeling of speaker pronunciation variants. Each speaker has his or her own unique pronunciations (and context-dependent variations), so that no one standard lexicon is able to cover all of the speaker’s variations. Creating speaker-dependent pronunciation lexicons for automatic speech labeling of our TTS voice d...
متن کاملStudy on Framework for Chinese Pronunciation Variation Modeling
The pronunciation variations, which badly influenced the performance of ASR system, are serious in continuous speech, especially in spontaneous speech. Many research works are focused on pronunciation variation modeling in recent years. A framework for Chinese pronunciation variation modeling is described in this paper. The main idea is that the pronunciation variations are hidden in the recogn...

Pronunciation variability is present in both native and foreign words. Since pronunciation variability constitutes a problem for automatic speech recognition (ASR) systems, modeling pronunciation variation for ASR has been the topic of various studies. In most studies, modeling pronunciation variation was attempted within the standard framework used in mainstream ASR systems. Given that some as...
متن کاملData-driven lexical modeling of pronunciation variations for ASR
In this paper a method for the automatic construction of a lexicon with multiple entries per word is described. The basic idea is to transform a reference word transcription by means of stochastic pronunciation rules that can be learned automatically. This approach already proved its potential (Cremelie & Martens, 1999), and is now brought to a much higher level of performance. Relative reducti...
