Jak badać samogłoski metodami akustycznymi? Propozycja metody opartej na względnych częstotliwościach formantowych oraz modelu samogłosek podstawowych

Abstract

How to study vowels using acoustic methods? A proposal of a method based on relative formant frequencies and cardinal vowels model. Part II . The second part of the paper consists of a list of relative formant frequencies of model vowels (the method of calculation was discussed in the first part). In this part, a test of the proposed method is designed using several new devices, such as the articulatory difference between vowels (expressed both as an integer and as a percentage), and the percentage distance between the analysed vowels and the particular model. In addition, a few simple statistics such as median, mode and arithmetic mean are used. The test itself consists of recognizing new vowels as pronounced by three different phoneticians. The calculations lead to the conclusion that recognition of vowels carried out with the use of the proposed method produces very accurate results which, most importantly, do not deviate in most instances from the expected values (the difference between the recognized vowel and the vowel described by the speaker did not exceed 40%). In conclusion, this part of the paper describes the advantages and limitations of the proposed method, and suggests possible solutions which may help improve the results in the future.
