Is Phonological Awareness Related to Pitch, Rhythm, and Speech-in-Noise Discrimination in Young Children?

Purpose: Phonological awareness (PA) requires the complex integration of language, speech, and auditory processing abilities. Enhanced pitch and rhythm discrimination have been shown to improve PA and speech-in-noise (SiN) discrimination. The screening of pitch and rhythm discrimination, if nonlinguistic correlates of these abilities, could contribute to screening procedures prior to diagnostic assessment. This research aimed to determine the association of PA abilities with pitch, rhythm, and SiN discrimination in children aged 5-7 years old. Method: Forty-one participants' pitch, rhythm, and SiN discrimination and PA abilities were evaluated. To control for confounding factors, including biological and environmental risk exposure and gender differences, typically developing male children from high socioeconomic statuses were selected. Pearson correlation was used to identify associations between variables, and stepwise regression analysis was used to identify possible predictors of PA. Results: Correlations of medium strength were identified between PA and pitch, rhythm, and SiN discrimination. Pitch and diotic digit-in-noise discrimination formed the strongest regression model (adjusted R-2 =.4213, r =.649) for phoneme-grapheme correspondence. Conclusions: The current study demonstrates predictive relationships between the complex auditory discrimination skills of pitch, rhythm, and diotic digit-in-noise recognition and foundational phonemic awareness and phonic skills in young males from high socioeconomic statuses. Pitch, rhythm, and digit-in-noise discrimination measures hold potential as screening measures for delays in phonemic awareness and phonic difficulties and as components of stimulation programs.

Automated summary

The study identified medium strength correlations between phonological awareness and pitch, rhythm, and speech-in-noise discrimination in children aged 5-7 years old. Pitch and diotic digit-in-noise discrimination were found to be the strongest predictors of phoneme-grapheme correspondence.
