Formants of Speech for Biometric Identification System
Binsu C. Kovoor · INTERNATIONAL JOURNAL OF COMPUTER APPLICATION · 2017
In hands free security system, speech is the widely used bio-feature.Extracted formant frequencies of human speech are utilized for the identification of a person.In this study, a prototype system was developed and tested.The advantage of the system is that it can be used without the knowledge of the end users.The system was developed in four modules.In the first module the speech samples are recorded.The formant frequencies are extracted from the the speech samples and recorded in a knowledge base in the second module.The autoregressive (AR) models are built in the third module.The testing is carried out in the fourth module.The influence of the envelop threshold and orders of AR model is examined to identify the optimum performance of the system.
