SUMMARY The authors recorded the sound signals during suckle feeding of six normal infants within the first two postnatal days. The sounds were recorded onto a cassette tape-recorder from a small microphone attached to the infant's neck, then display

The performance of 32 children with language impairment—11 with expressive language impairment only (LI-E subgroup) and 21 with both receptive and expressive language impairment (LI-ER subgroup)—and of 22 children without language impairment (LN

Twenty-four children with language impairment (LI) and 22 children without language impairment (LN) participated in a study of discrimination, identification, and serial ordering of the highly dissimilar vowels/a/ versus /i/, and the highly similar v

SUMMARY Pharyngeal swallows during infant suckle-feeding are associated with a characteristic sequence of sounds audible by stethoscope or by an accelerometer or microphone held over the larynx. In rhythmically feeding term-born neonates, the delinea

It has been claimed that language‐learning disordered children have impaired rapid‐rate auditory processing. One manifestation is the failure to identify stop‐vowel syllables; another less fine‐grained discrimination of stop‐vowel syllables

It has been proposed that SLI children have a rapid‐rate auditory‐processing deficit, and alternatively, that they have special difficulty with signals that are low in information or degraded. In the present study, steady‐state vowel pairs, /a/

Behavioral and acoustic reflex thresholds were determined for five normal-hearing subjects in response to carrier signals of 500 and 2000 Hz which were unmodulated or modulated sinusoidally at rates of 2, 20, and 200 times per second with frequency d

The present investigation was designed to study temporal‐masking effects produced by speech‐like signals. The masking stimuli were computer‐generated vowel‐like signals; two durations (100 and 200 msec) of each of four vowel‐like signals we

According to an acoustical theory of speech production, the spectra of voiceless fricatives can be characterized by poles and zeros whose frequency locations are dependent on the vocal‐tract configuration and on the location of the source of excita

Five normal‐speaking adult males were taught to produce speech using an electrolarynx. Speech phoneme intelligibility was measured in a closed‐set word discrimination test and through phonetic transcriptions of the spoken materials. Mean percenta
