Speaker Verification using LabVIEW
The speaker verification is a process of verifying the identity of the claimants. It performs one to one comparison between a newly input voice print and the voice print for the claimed identity that is stored in the database. In this paper, linear predictive coding co-efficient has been used for formant detection. The peak frequencies in the frequency response of vocal tract are formants, whic...
متن کاملSpeaker Verification Using Speaker-Specific Prompts
Intraand inter-speaker information, which include acoustical, speaker style, speech rate and temporal variation, despite their critical importance for the verification of claims, still have not been captured effectively. As a result of such modeling deficiency, existing speaker verification systems generally test claimed utterances with interfacing procedures that are common to all speakers. In...
متن کاملSpeaker verification using minimum verification error training
We propose a Minimum Verification Error (MVE) training scenario to design and adapt an HMM-based speaker verification system. By using the discriminative training paradigm, we show that customer and background models can be jointly estimated so that the expected number of verification errors (false accept and false reject) on the training corpus are minimized. An experimental evaluation of a fi...
متن کاملUsing Exciting and Spectral Envelope Information and Matrix Quantization for Improvement of the Speaker Verification Systems
Speaker verification from talking a few words of sentences has many applications. Many methods as DTW, HMM, VQ and MQ can be used for speaker verification. We applied MQ for its precise, reliable and robust performance with computational simplicity. We also used pitch frequency and log gain contour for further improvement of the system performance.
متن کاملSpeaker Verification Using Coded Speech
The implementation of a pseudo text-independent Speaker Verification system is described. This system was designed to use only information extracted directly from the coded parameters embedded in the ITU-T G.729 bitstream. Experiments were performed over the YOHO database [1]. The feature vector as a short-time representation of speech consists of 16 LPC-Cepstral coefficients, as well as residu...
