Forensic DNA database is by using the DNA profile of the felonious criminals DNA analysis method, the database collects of the result of analysis. The identification management system (IMS) of the scientific investigation which is particular through the database retrieval is Forensic DNA database if the DNA profile of the detected from the crime scene evidence of many events DNA profile and suspect related to it is secured. Forensic DNA database needs for legislation of Forensic DNA database for identifying possible convicted offenders and suspects for recordable offences. On 25 January 2010, as legislation of ‘Act on the protection and use of DNA identifying information’ in Korea after long days of dispute.

Through these cases, we can know that forensic DNA database provide the criminal justice systems with not only an efficient way of crime solving but also prevention of crime.

In general, triangular shape filters are used in the filter bank when we get the MFCCs from the spectrum of speech signal. In [1], a new feature extraction approach is proposed, which uses specific filter shapes in the filter bank that are obtained from the spectrum of training speech data. In this approach, principal component analysis technique is applied to the spectrum of the training data to get the filter coefficients. In this paper, we carry out speech recognition experiments, using the new approach given in [1], for a large amount of telephone speech data, that is, the telephone speech database of Korean connected digit released by SITEC. Experimental results are discussed with our findings.
