Universals Archive (Universal #1926) indicates a universal tendency for sound symbolism in reference to the expression of diminutives and augmentatives. The research ( Štekauer et al. 2009 ) carried out on European languages has not proved the tendency at all. Therefore, our research was extended to cover three language families – Indo-European, Niger-Congo and Austronesian. A three-step analysis examining different aspects of phonetic symbolism was carried out on a core vocabulary of 35 lexical items. A research sample was selected out of 60 languages. The evaluative markers were analyzed according to both phonetic classification of vowels and consonants and Ultan's and Niewenhuis' conclusions on the dominance of palatal and post-alveolar consonants in diminutive markers. Finally, the data obtained in our sample languages was evaluated by means of a three-dimensional model illustrating the place of articulation of the individual segments.

ABSTRACTPronunciation variation is under-studied in infant-directed speech, particularly for consonants. Regressive place assimilation involves a word-final alveolar stop taking the place of articulation of a following word-initial consonant. We investigated pronunciation variation in word-final alveolar stop consonants in storybooks read by forty-eight mothers in adult-directed or infant-directed style to infants aged approximately 0;3, 0;9, 1;1, or 1;8. We focused on phonological environments where regressive place assimilation could occur, i.e., when the stop preceded a word-initial labial or velar consonant. Spectrogram, waveform, and perceptual evidence was used to classify tokens into four pronunciation categories: canonical, assimilated, glottalized, or deleted. Results showed a reliable tendency for canonical variants to occur in infant-directed speech more often than in adult-directed speech. However, the otherwise very similar distributions of variants across addressee and age group suggested that infants largely experience statistical distributions of non-canonical consonantal pronunciation variants that mirror those experienced by adults.

The minimum initial-portion durations required by listeners for the correct identification of spoken isolated vowels and consonant-vowel (CV) syllables were determined. Eight vowels /i i u u æ ε a Λ/ and 64 CVs comprised of each of eight consonants /b p d t g k d 3 t∫/ in combination with each of the eight vowels were used. Segments consisted of the initial 10 to 150 milliseconds of each stimulus in 10-msec steps. The major findings were (1) clues for better than chance correct identification of tongue advancement and tongue height values for isolated vowels occur within the first 10 msec of the stimuli whereas approximately 30 msec of the stimuli are needed for the tense-lax feature to reach threshold, (2) clues for better than chance correct identification of place of articulation for the stop consonants are found within the initial 10 msec of the CVs whereas approximately 22 msec are needed for the voicing threshold to reach threshold, and (3) the threshold of voicing increases from front to back place of articulation for the stop consonants. The implications of the findings are discussed.
