The paper describes formant based speaker normalization method suitable for speech visualization and articulation training systems. The method estimates the error function obtained from speaker formant characteristics for a given vowel. Estimated error function gives information for critical band filter shifting on mel-warped frequency scale. The paper also describes accurate technique for form...

Wavelet Transformations and music have several things in common: both have something to do with time-frequency descriptions and constant relative bandwidth analysis. In this paper, we describe some applications of the Continuous Wavelet Transform in the processing of music. The main applications are analysis and pitch-shifting (or the equivalent time-stretching), for which we give an algorithm.

2014 A system consisting of two resonant circuits coupled inductively with a resistive SQUID was investigated using an analog computer. Here it is reported on several results of special interest for microwave receiver application, namely spectra of heterodyning products, frequency shifting and operation at zero input.

The aim of this paper is to present results on digital processing of sounds by means of both dispersive delay lines and pitch-synchronous transforms in a unified framework. The background on frequency warping is detailed and applications of this technique are pointed out with reference to the existing literature. These include transient extraction, pitch shifting, harmonic detuning and auditory...

a field study was undertaken with four farming systems (fs) such as; grasses and fodders, agro-forestry, agriculture (new farming systems) and shifting cultivation (old practice), to investigate the effect of land use on the soil properties, erosion and crop productivity on a loamy acidic alfisol. besides crops, the livestock were also kept and their dropping were incorporated in the respective...

Involuntary attention shifting, i.e., detecting and orienting to unexpected stimulus changes, may be altered at low brain serotonin (5-hydroxytryptamine; 5-HT) levels. This was studied in 13 healthy subjects (21-30 years old; 6 females) by using a dietary challenge, acute tryptophan depletion (ATD), which decreases 5-HT synthesis in the brain. Five hours after ingestion of either ATD or control...
