Cross-language analysis of phonetic units in language addressed to infants.

In the early months of life, infants acquire information about the phonetic properties of their native language simply by listening to adults speak. The acoustic properties of phonetic units in language input to young infants in the United States, Russia, and Sweden were examined. In all three countries, mothers addressing their infants produced acoustically more extreme vowels than they did when addressing adults, resulting in a "stretching" of vowel space. The findings show that language input to infants provides exceptionally well-specified information about the linguistic units that form the building blocks for words.

Central auditory processing of peripheral vowel spectra.

This paper presents a review of recent experiments in vowel perception done at the Pavlov Institute of Physiology in Leningrad. The data concern three topics: experimental procedures appropriate for the study of phonetic quality perception, processing of the auditory spectral shape of a vowel, and processing of the auditory dynamic spectrum of a vowel.

[Principles of temporal processing of spectral information during vowel perception].

Pairs of "one-formant pulses" with 10 ms onset-to-onset interval and highly different F values for the first and the second pulse (LH and HL pairs) were used in vowel identification experiment. Response distributions corresponding to these stimuli and to "stationary" two-formant and one-formant pulse pairs were compared to calculate the phonetic distance between stimuli. The results are in favour of low-pass filtering of excitation pattern with sampling at the stimulus offset.

[Factors determining the subjective closeness of vowel-like stimuli].

Conditions for two formants combined into one spectral cue or giving rise to two spectral cues were studied by psychoacoustical methods. Critical distance between formant frequencies corresponding to perceptual separation of the formants was measured. Interdependence between the formant amplitudes and the equivalent frequency was revealed for stimuli with closely spaced formants. For stimuli with widely spaced formants formant amplitudes appeared to be unimportant for vowel quality.

[Phenomenon of the accumulation of spectral information in vowel-like stimulus].

Studies have been made on the perception of vowel-like stimuli formed by interchange of impulses with various form of the spectrum following with a period of 14 ms. Application of similar stimuli in earlier investigations revealed a phenomenon of accumulation of spectral information during the interval within a stimulus and allowed to reject a hypothesis of averaging directly the auditory dynamic spectrum. In the first part of investigation, we checked and did not confirm a hypothesis of screening from the bulk of the accumulated data of those spectral configurations which are distinctly different from natural vowels. In the second part of investigation, new results were obtained which are predicted by the hypothesis of average meanings of vowel traits (calculated from impulse spectra) and which contradict the hypothesis of current phonemic discrimination with accumulation of the obtained values of similarity of the spectrum with phonemic standards.
