- Abstract
- In this paper, we investigated the parameters for determining the degree of pronunciation improvement by using the formant comparison method. Many speech parameters have been studied to identify inaccurate pronunciation features. Generally, the method of grasping the inaccurate pronunciation is analyzed by using the change of pitch and formant. Formants have various information such as the individual’s uniqueness, clarity and physical condition, and the pronunciation status can also be analyzed. Analysis of the pronunciation through the pronunciation agency may cause difficulty in the analysis due to the pronunciation difference of the individual. On the other hand, analysis of pronunciation through vocal organs facilitates analysis because consonants or vowels are applied only to consonant vowels rather than vowel sounds. Especially dentures are artificial teeth, so there are many problems such as rattling and it is difficult to pronounce correctly. The jaws and teeth can be analyzed with the formant information of the high frequency region in the voice signal, and the degree of pronunciation improvement according to the presence or absence of the denture can be grasped. Therefore, in this paper, the research was carried out to extract the degree of pronunciation enhancement by changing the information of the third formant and the fourth formant. As a result, the longer the sentence was, the more pronounced the error was. © Research India Publications.
