The Mongolian Vowel Acoustic Model Based on the Clustering Algorithm.

In order to solve the problem of vowel acoustic modeling in the Mongolian language and provide more scientific core technical support for speech recognition system, a vowel acoustic model based on the clustering algorithm and speech recognition technology was proposed. The language vowel recognition system and Mongolian speech recognition system are constructed, the Mongolian vowel acoustic database is mainly designed, and the number of vowel samples is constantly increased to ensure the acoustic and linguistic phenomena that may be encountered in the Mongolian vowel database. At the same time, classification modeling and context modeling are used to improve the accuracy of the acoustic model. Through experiments, it is found that the experimental results of sparse tritones show that the model has the highest recognition accuracy of 45% for sentences and 86% for words, which is more than 2% higher than before, providing some technical support for Mongolian learning and pronunciation.
