  • Comparison of the phonemes used as elements of continuous speech (in sentences) or as elements of isolated words
    Zemljak Jontes, Melita
    The difference between phonemes used as elements of continuous speech and the phonemes used as elements of isolated words is very important for speech recognition. Namely, some phonemes are ... pronounced differently if used in continuous speech (e.g. in sentences) or if used in isolated words. The main problem represent the vowels uttered in continuous speech. They are largely submerged to the so-called modern vocal reduction, according to which the vowels, especially the ones of high and middle position of the tongue during utterance, change their quality into a semi-vowel schwa (e [reduced vowel]) or dissapear completely. The issue is especially frequent with non-stressed vowels, but it is not unknown with consonats either (then it is not called MVR), particulary in a very rapid speech, which altogether makes the recognition of phonemes and allophones unpleasantly difficult. Since the Slovene language is not just one speech without different colloquialisms but consists of seven dialectal groups and of at least forty five dialects with different speeches for almost every village or town, different problems occur. For example, it is always an issue when working on recorded speech material, whether the speech should be recorded in RP or in dialects. The material recorded for SNABI is meant to deal with Slovene RP, nevertheless, the colloquialisms, such as short unstressed e instead of in Slovene RP only possible short unstressed e [broad e], are uttered. A huge difficulty represent the qualities of vowels o and e, that is of o before the phoneme v(w) before consonats or in the final word position and of e before j in the same position, which, if unstressed, should be of approximately the same quality as the phoneme schwa (e [reduced vowel]), but especially in continuous speech this is not the case. These an also some other changes in quality differ from one to another dialectal group in Slovenia and would thus need of a further insight into the matter and some serious research. One of the main difficulties when comparing consonants in isolated words with consonants in continuous speech (sentences) is the beginning of plosives, especially if they are in a word (in isolated words) or sentence (in continuous speech) initial position. Because of the closure before explosion, it is extremely difficult to denote the exact beginning of the utterance. In continuous speech, plosives in word initial but not sentence initial position represent no problem. In general, phonemes uttered in isolated words are pronounced in a much more precise manner than in continuous speech (in sentences) and thus the length ofthese phonemes shortens in the latter
