Advanced Speaker Verification System Using Wavelets
نویسنده
چکیده
This paper presents an advanced speaker verification system using wavelet transforms. The conventional signal processing techniques assume the signal to be stationary and are ineffective in recognizing non stationary signals such as voice signals. Voice signals which are more dynamic could be analysed with far better accuracy using wavelet transform. The developed voice verification system is word independent voice verification system combining the RASTA and LPC. The voice signal is filtered using the special purpose voice signal filter using the Relative Spectral Algorithm (RASTA).The signals are de-noised and decomposed to derive the wavelet coefficients and there by a statistical computation is carried out. Further the formant of the resonance of the voices signals is detected using the Linear Predictive Coding (LPC). KeywordsLPC, RASTA, Voice verification model

Using 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 کاملBest speaker-based structure tree for speaker verification
In this paper we study the use of the Wavelet transform for textdependent speaker verification purposes. A new algorithm to construct the best admissible tree is proposed which has been used to obtain a speaker dependent tree library. Every tree in this library corresponds to the best structure for a given speaker, therefore the extracted parameters from a given tree are well suited and discrim...
متن کاملWavelet packet based speaker verification
In an attempt to find out a more appropriate representation of a speech signal for the task of speaker recognition, we study alternative ways to represent speakers’ voices individuality. A novel wavelet packet based set of speech features, apposite for speaker recognition, is proposed. We exploit the capabilities offered by the plethora of existing wavelets, along with the powerful set of ortho...
