The Phonetics and Phonology of the Polish Calling Melodies.

Two calling melodies of Polish were investigated, the routine call, used to call someone for an everyday reason, and the urgent call, which conveys disapproval of the addressee's actions. A Discourse Completion Task was used to elicit the two melodies from Polish speakers using twelve names from one to four syllables long; there were three names per syllable count, and speakers produced three tokens of each name with each melody. The results, based on eleven speakers, show that the routine calling melody consists of a low F0 stretch followed by a rise-fall-rise; the urgent calling melody, on the other hand, is a simple rise-fall.

[Improvement of the PERG parameters measurement accuracy in the continuous wavelet transform coefficients domain].

Purpose: To determine parameters of the pattern electroretinogram (PERG) waveforms in the continuous wavelet transform (CWT) coefficients domain important in more precise clinical assessment of the recordings.

Material And Methods: 102 normal PERG recordings were studied in two age groups (< or = 50 years, > 50 years). Continuous wavelet transform analysis was performed using the MatLab 7.
