Speaker identification is a widely used technique in several security systems. In remote
access systems, speaker utterances are recoded and communicated through a …

This paper proposes a solution to the problem of velocity and position estimation for a class
of oscillating systems whose position, velocity and acceleration are zero mean signals. The …

This thesis deals with text-independent solutions for voice conversion. It first introduces the
use of vocal tract length normalization (VTLN) for voice conversion. The presented variants …

This paper proposes a multimodal biometric system that combines iris recognition and
speaker identification systems using the energy compaction and time frequency resolution of …

This paper presents a comparison between different audio speech encryption and
decryption techniques for audio speech signals based on 2-D chaotic map algorithms with …

The present work focuses on the problem of velocity and position estimation. A solution is
presented for a class of oscillating systems in which position, velocity and acceleration are …

The multi resolution nature and energy compaction of wavelet transform particularly makes
them suitable for analysis of biological features both behavioral and physiological. The …

Jednym z ważniejszych parametrów charakteryzujących źródło mowy dźwięcznej jest
częstotliwość podstawowa tonu krtaniowego (F0), która odpowiada częstotliwości …

Pitch period estimation is one of the important issues in speech processing. Wavelet
transform has been used for pitch detection in recent research. In this paper a new modified …

Using the energy compaction and time frequency resolution of wavelet analysis, the paper
proposes to develop a multimodal biometric system that combines iris recognition and …
