Development of an Intelligent Decision Support System for Identifying a Person by Voice Signal Response

In this paper, a hierarchical schematic model is developed to identify a person. The system is based on persons' voice signal responses. The proposed system detects a person by their voice signal. In the modern age, the incidental description is used as a resource for criminal investigation. In the designing model, an experimental circuit is used to obtain frequency response of different voice signals. After that, an algorithm is developed and implemented in programming language 'C' to identify the particular voice signal response.
