Keywords: Speech Recognition Systems Arabic Language Phonetic Dictionary pronunciation variations. In particular, we propose a class of feature-based pronunciation models represented as dynamic Bayesian networks (DBNs). word variation provide a good performance. Although it is well-known that many phenomena can be attributed to this "semi-independent evolution" of features, previous models of pronunciation variation have typically not taken advantage of this.

Text to Speech Online with Realistic Voices. Features may correspond to the positions of the speech articulators, such as the lips and tongue, or to acoustic or perceptual categories. We present an alternative approach, in which many types of variation are explained by representing a pronunciation as multiple streams of linguistic features rather than a single stream of phones. Common rule sets, however, typically leave many pronunciation variants unaccounted for and increase word confusability due to the coarse granularity of phone units. One approach to handling this variation consists of expanding the dictionary with phonetic substitution, insertion, and deletion rules. This is one factor in the poor performance of automatic speech recognizers on conversational speech.
