What is the meaning of identifying the speaker?

Identification is the process of determining from which of the registered speakers a given utterance comes. Verification is the process of accepting or rejecting the identity claimed by a speaker. Most of the applications in which voice is used to confirm identity are classified as speaker verification.

What is the basis of voice identification?

To verify an enrolled person's identity, the biometric voice recognition system captures a new speech sample, creates a template from the sample, and compares it against the enrollment template. A strong match between templates indicates that the same person spoke both samples, thus verifying the person's identity.

How do you classify a speaker?

Speaker classification requires a sufficiently accurate functional description of speaker attributes and the resources used in speaking, to be able to produce new utterances mimicking the speaker's current physical, emotional and cognitive state, with the correct dialect, social class markers and speech habits.

How does speaker recognition work?

Speaker recognition is based on the sound of the voice. Speaker recognition has two forms: Text dependent - with the subject uttering a specific password or pass phrase. Text independent - with the subject speaking in an unconstrained manner.

What are the four different ways to perform speaker recognition?

Speaker recognition is a pattern recognition problem. The various technologies used to process and store voice prints include frequency estimation, hidden Markov models, Gaussian mixture models, pattern matching algorithms, neural networks, matrix representation, vector quantization and decision trees.
