SPEAKER RECOGNITION

Introduction
Different machine can be use to recognition the voice of the speaker. Through making comparison of the current speech and the previous stored speech we can be able to recognize the voice of someone just by hearing him/her speech.

Speaker recognition is the process of automatically recognizing who is speaking on the basis of individual information included in speech signals. There is the different between speaker recognition and speech recognition. Speaker recognition is the recognizing who is speaking. Speech recognition is the recognizing what is being said.

Speaker recognition can be classified into two classes that is:
Speaker Identification is the identification of a single user voice among many users voice.Here they will be many voices but machine make the identication of a single voice.
Speaker Verification is the process of verify a single voice by compared with the previous voice with the current one.

System of speaker recognition can be work through the conversion of the signals that is analogy speech signals to digital siginals.Comparisional of the current speech and the previous stored speech that is the store speech must be equal to current speech in order for machine to recognize and produce the outcome the voice.

Speaker recognition is important because is used to help in control of access to restricted services, for example, phone access to banking, database services, shopping or voice mail, and access to secure equipment.
For security purpose and in military operations.
In different areas speaker recognitionation techniques can be used:
Authentication; allows the users to identify themselves using nothing else but their voices.
Surveillance; for security agencies i.e. means of collecting information.
Forensic; for proving the identity of the recorded voice.
The system can be faced with the problems like
Determining what the correct units to be recognized that is the voice to be recognize must be contain correct units and words. Finding the boundaries of these units in the signal also variability in unity of speech.

In order to overcome the problem we should be use the exactly word required, maintain the voice pitch and to be aware of the environment condition.
Generally the system is important, because we can be able to recognize the voice of different people and also machine can help us to recognize the voice through comparison of the voices. Through the use of machine time is saved that is for the short time to can recognition a lot of the voices.
