CONTEXT-INDEPENDENT CHINESE INITIAL-FINAL ACOUSTIC MODELING
Jing Li, Wenhu Wu · 2000
In this paper, a method for the Context-Independent (CI) Chinese Initial-Final acoustic modeling for continuous speech recognition task is proposed. The initial-final (I/F) structure is a characteristic of Chinese language. Initials and finals are smaller units compared to syllables, the use of which is helpful to reduce the number of SRUs. Furthermore, it should be possible to build context-dependent (CD) models. In our experiments, we use knowledge-based criteria to define the CI initial-final units. There are four kinds of CI initial-final units in this paper. The experimental results show that the accuracy of the CI initial-final models is near to or lower than that of the CI syllable model, but the size of model is significantly reduced.
