Hereinafter, music recognition and voice recognition, which are main technologies used in the audio data search unit 350, will be described in detail.

Music recognition refers to identifying what music the audio signal represents using the characteristics of the audio signal. In general, audio fingerprint information may be applied as an audio feature for music recognition.

Audio fingerprint refers to a feature that can representatively represent an audio signal, and is used to classify an audio signal or identify an audio signal and to identify music among audio signals. Audio fingerprints can be classified into two types according to the method. A method of identifying music through similarity comparison by modeling a pattern of feature vectors of a music signal and an audio hashing method using a rate of change of feature values according to time and dimensions are provided. have. For example, when the audio hashing method is used in the present invention, when performing the search in the audio data search unit 350, only the audio hash value may be compared to determine whether a correspondence is present.

Speech recognition generally refers to recognizing a human voice and recognizing a word or a sentence. In speech recognition technology, recognizing a person who speaks a human voice and speaks is called speaker recognition. In the present invention, a speaker recognition technology may be mainly used among voice recognition technologies.

In the case of speech recognition, HM (Hidden Markov Model) or GMM (Gaussian Mixture Model) using MFCC (Linear Predict Cepstral Coefficient) or LPCC (Linear Predict Cepstral Coefficient) Pattern modeling). In general, HMM is mainly used for speech recognition, and GMM is mainly used for speaker recognition. Hereinafter, the feature parameters and modeling methods will be described in detail.

MFCC is a typical characteristic parameter of speech signal. The spectrum obtained by frequency analysis of one frame of speech signal is applied to Mel-scale filter bank considering Mel's auditory characteristics. Refers to the cepstrum coefficient obtained by (Discrete Cosine Transform).

LPCC is an LPC coefficient that minimizes the error by predicting a speech sample from a linear combination of previous n speech samples at a specific time based on the assumption that speech samples can be effectively predicted from the previous n speech samples at a specific time. The coefficient is obtained, and the cepstrum coefficient of the coefficient is obtained.

HMM is a method of applying the concept of the Markov chain by linking probability distribution with time information in modeling a speech signal. The parameters of the HMM can be obtained by applying the learning speech data to well-known learning algorithms such as the Baum-Welch algorithm.

GMM is a part of the HMM described above. In the case of HMM, one probability model is composed of n stable states. However, GMM represents a probability model using a Gaussian model based on the speech data probability model following the Gaussian model. In this case, not one Gaussian model can be expressed as n mixture models.
