Speaker identification matlab help

Voice is one of way to communicate and express yourself. Speaker recognition is a process carried out by a device to recognize the speaker through the voice. This study designed a speaker recognition system that was able to identify speakers based on what was said by using dynamic time warping DTW method based in matlab. To design a speaker recognition system begins with the process of reference data and test data. Both processes have the same process, which starts with sound recording, preprocessing, and feature extraction. The results of the feature extraction process from the two data will be compared using the DTW method.

Date Created Other Date degree. Extent xiv, 94 pages. Description Traditional fixed pass-phrase or text-dependent speaker verification systems are vulnerable to replay or spoofing attacks.

Random pass-phrase generation, speech verification and text-independent speaker verification could be combined to create a composite speaker verification system, robust to this spoofing problem. This thesis deals with combining speech verification with text-independent speaker verification for this purpose. A method to perform robust, automatic speech verification using a speech recognizer in a forced alignment mode is proposed and evaluated. A text-independent speaker verification system was developed in MATLAB for training and evaluating Gaussian mixture density-based, target speaker and background speaker models.

Equal-error rate is the performance metric used in all speaker verification evaluations. To speed up background model training, a simple technique based on sub-sampling or decimating speech frames is presented.

Evaluation of two different feature extraction implementations along with an evaluation of the impact on performance of different configurations of the speech features is also carried out. Further, to mitigate problems with reduced training data and to improve performance, Bayesian adaptation of background speaker models with target speaker training data is used to create target speaker models.

The performance of these models is evaluated and compared with conventional target speaker models. The impact of the length of test-utterances, variance limiting and the use of training data from multiple recording sessions has also been investigated. Note M.

MFCC Based Speaker Recognition using Matlab

Speech Recognition is the process in which certain words of a particular speaker will automatically recognized that are based on the information included in individual speech waves. This paper enlightens upon the invention as well as technological advancement in the field of voice recognition and also focuses upon different steps involved for speaker identification using MATLAB Programming. In this paper firstly we will going to perform speech editing as well as degradation of signals by the application of Gaussian Noise. This background noise then will success fully removed by the application of Butterworth Filter. Moreover, the technique applied here is to develop a code using MATLAB Programming which will compare the pitch and format vectors of a known speech signal which will then compare with the bunch of other unknown speech signals and prior to it choose the appropriate matches.

Documentation Help Center Documentation. In this example, you train three convolutional neural networks CNNs to perform speaker verification and then compare the performances of the architectures. The architectures of the three CNNs are all equivalent except for the first convolutional layer in each:. In the first architecture, the first convolutional layer is a "standard" convolutional layer, implemented using convolution2dLayer. In the second architecture, the first convolutional layer is a constant sinc filterbank, implemented using a custom layer. In the third architecture, the first convolutional layer is a trainable sinc filterbank, implemented using a custom layer. This architecture is referred to as SincNet [1]. Speaker identification is a prominent research area with a variety of applications including forensics and biometric authentication. Many speaker identification systems depend on precomputed features such as i-vectors or MFCCs, which are then fed into machine learning or deep learning networks for classification.

Documentation Help Center Documentation. This example demonstrates a machine learning approach to identify people based on features extracted from recorded speech. The features used to train the classifier are the pitch of the voiced segments of the speech and the mel frequency cepstrum coefficients MFCC. This is a closed-set speaker identification: the audio of the speaker under test is compared against all the available speaker models a finite set and the closest match is returned. Pitch and MFCC are extracted from speech signals recorded for 10 speakers.

Report Download. Technology, Nirma University is the record of work carried out by them under my supervision and guidance. The work submitted in our opinion has reached a level required for being accepted for the examination. AcknowledgementIn order to achieve better performance, we should have to learn our outside environment. There are lots of forces which will acting upon us to get the better result, but for that we have to change our attitude to see them. There are lots of problems we facing, but due to it we dont stop. It is not a good human being ,if he is stop. Yes, we are sometimes frustrated due to the problems we cant solve it.

Yadav Published Computer Science Speech is the natural and efficient way to communicate with persons as well as machine hence it plays an vital role in signal processing. In this paper cepstral method is used to find the pitch of speaker and according to that find out gender of the speaker.

Speech Recognition is the process in which certain words of a particular speaker will automatically recognized based on the information included in individual speech waves. Speech is one of the most important medium by which a communication can take place. The invention and widespread use of mobiles, telephones, data storage devices etc. These also brought about ever-increasing need to authenticate and identify individuals automatically. Biometrics which identifies the physical traits and behavioural characteristics that make each of us unique therefore becomes necessary as a natural choice for identity verification. Advances in Biometric technology promises an effective solution to the world security needs as it can accurately identify or verify individuals based upon their unique physical or behavioural characteristics.

You can play with score fusion weights here. However, for some features which does not yield very good results on validation set, we do not use them for blind test.
