Speech Enhancement System using SVM for Train Announcement

On the train, announcement speech is one of the important information to know the operation status. However, clarity of announcement speech is not enough because announcement speech is masked by noise. Therefore, new system is proposed to improve clarity of announcement speech based on sound classification. By classifying several sounds, users can select the announcement speech only they want to hear. In this paper, classifier is developed that distinguishes announcement speech using SVM. In the experiments, this classifier obtain that the accuracy of developed classifier is 96%.
