Base Claim:
1. A non-standard speech detection system that is capable of analyzing human voice to detect the speech style of an individual for verifying identity of the individual according to his speech style, the system comprising: at least one voice recording unit for recording personal standard speeches of the individual in his/her normal life; at least one voice database wherein the personal standard speeches recorded by the voice recording unit are stored as voice recordings; at least one acoustic examination module for determining acoustic speech characteristics of the individual from the voice recordings stored in the voice database; at least one speech recognition module for determining behavioral characteristics and speech content characteristics of the individual from the voice recordings stored in the voice database and capable of making speech analysis by converting the voice recordings into text; at least one analysis module for creating a personal standard speech style model by examining the acoustic speech characteristics and the behavioral speech characteristics of the individual determined by the acoustic examination module and the speech content characteristics of the individual determined by the speech recognition module; at least one personal standard speech style model database wherein the personal standard speech style models created by the analysis module are recorded in a personalized way; at least one evaluation module for comparing a new voice input with the recorded personal standard speech style models; at least one transmission unit capable of transmitting result reached after the comparison of the evaluation module to related units, wherein the speech content characteristics of the individual include sentence patterns, words and phrases, language model n-gram parameters, and semantic parameters obtained from the text, wherein the evaluation module evaluates whether speech content characteristics, acoustic speech characteristics, and behavioral speech characteristics of the new voice input match the personal standard speech style model of the individual and verifies identity of a caller producing the new voice if a match occurs, wherein the behavioral speech characteristics of the individual include speech behavioral characteristic parameters of the individual, interruption interval for another party to the conversation, and speech overlap with the other party, and wherein the speech behavioral characteristic parameters include speaking speed, monotony, hesitance, and loudness of voice.

Claim 5:
5. The non-standard speech detection system according to claim 1 , wherein the evaluation module determines whether the speech is performed in a stand/non-standard way by comparing the new voice inputs taken in the individual's communications made over a voice communication channel with the personal speech style models of the individual recorded in the standard speech style model database.
