Children’s perception of speech in multitalker babble

Abstract

Children 5, 9, and 11 years of age and young adults attempted to identify the final word of sentences recorded by a female speaker. The sentences were presented in two levels of multitalker babble, and participants responded by selecting one of four pictures. In a low-noise condition, the signal-to-noise ratio (SNR) was adjusted for each age group to yield 85% correct performance. In a high-noise condition, the SNR was set 7 dB lower than the low-noise condition. Although children required more favorable SNRs than adults to achieve comparable performance in low noise, an equivalent decrease in SNR had comparable consequences for all age groups. Thus age-related differences on this task can be attributed primarily to sensory factors.

Effects of contextual support on preschoolers’ accented speech comprehension

“…These findings concur with other research suggesting that children are less adept than adults at comprehending speech in ideal (Hazan & Barrett, 2000;Ohde & Haley, PRESCHOOL ACCENT COMPREHENSION 1997) and non-ideal listening conditions (Fallon et al, 2000(Fallon et al, , 2002. Findings of non-adultlike accent comprehension in young children are also consistent with accounts of protracted perceptual development (e.g.…”

Speech Perception in Children Under Noisy Situations

“…Vários testes clínicos foram elaborados para a avaliação da percepção da fala em crianças pequenas devido à necessidade de se estudar quais são as habilidades auditivas que a criança desenvolve frente ao uso dos aparelhos de amplificação sonora individuais (AASI) ou do implante coclear (IC) (2,3,4). Esses procedimentos permitem também avaliar o programa de habilitação ou reabilitação auditiva.…”

The effect of amplitude modulation on intelligibility of time-varying sinusoidal speech in children and adults

“…Numerous studies have shown differences between children and adults on a variety of speech-perception tasks in noise and reverberation (e.g., Fallon, Trehub, & Schneider, 2000;Hall, Grose, Buss, & Dev, 2002;C. E. Johnson, 2000) and in the presence of reduced spectral cues (Eisenberg, Shannon, Martinez, Wygonski, & Boothroyd, 2000).…”

“…Explanations include peripheral factors such as auditory sensitivity (Schneider, Trehub, Morrongiello, & Thorpe, 1986, central auditory processes (Allen & Wightman, 1994, attention and memory (Buss, Hall, Grose, & Dev, 1999;Hill, Hartley, Glasberg, Moore, & Moore, 2004;Wightman, Callahan, Lutfi, Kistler, & Oh, 2003), language experience (Eisenberg et al, 2000), poor information extraction (Grose, Hall, & Dev, 1997), and task difficulty (Fallon et al, 2000).…”
