چکیده
This research is directed toward transforming a speech signal into a new speechlike signal that is perceived as identical to the original signal in all respects except that it is articulated at a rate different from that of the original speech. Such a technique is of interest in a variety of applications including learning a second language, developing talking books for the blind, generation of stimuli for psychological experiments, enhancement of intelligibility, and interactively searching through large quantities of speech data.

متن کاملDigital Binary Phase-shift Keyed Signal Detector
We have developed the effective algorithm for detecting digital binary phase-shift keyed signals. This algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides high interference immunity by identifying signal presence when signal-to-noise ratio is much less that its w...
متن کاملEstimating the Number of Wideband Radio Sources
In this paper, a new approach for estimating the number of wideband sources is proposed which is based on RSS or ISM algorithms. Numerical results show that the MDL-based and EIT-based proposed algorithm havea much better detection performance than that in EGM and AIC cases for small differences between the incident angles of sources. In addition, for similar conditions, RSS algorithm offers hi...
متن کاملTransition from analogue-to-digital nuclear electronics for precise gamma radiation spectroscopy: advantages and limitations
In this paper, digital signal processing for precise gamma ray spectroscopy is presented. The basis of this system is a 14bit waveform digitizer which samples the output of pre-amplifier signals directly. The advantages and limitations of the digital spectrometer compared with analog spectrometer has been tested and analyzed from precise gamma ray spectroscopy point of view. The results shows t...
