On the Difference of Scoring in Speech in Babble Tests

Area of Science:

• Audiology
• Neuroscience
• Speech and Hearing Sciences

Background:

• Hearing assessment involves more than peripheral auditory function.
• Speech-in-noise tests are crucial for evaluating comprehensive hearing abilities.
• Auditory Processing Disorder (APD) affects how the brain processes auditory information.

Purpose of the Study:

• To compare the effectiveness of syllable versus word scoring in the Greek Speech-in-Babble (SinB) test.
• To determine which scoring method offers greater discriminative ability for children with and without APD.
• To assess the impact of scoring method on the resolution capacity of the SinB test.

Main Methods:

• The study involved 22 children with APD and 33 typically developing children (ages 6-12).
• Participants completed the Greek Speech-in-Babble (SinB) test using both syllable and word scoring.
• Statistical analyses included three-factor and two-way analyses of variance and Cohen's d calculations.

Main Results:

• Syllable scoring demonstrated greater discriminative ability between groups compared to word scoring.
• Both groups of children showed poorer performance on word-based measures (higher SNR50%) than syllable-based measures.
• Larger Cohen's d values for syllable-based scores indicated a greater difference between the groups.

Conclusions:

• The scoring method significantly impacts the resolution capacity of the Speech-in-Babble test.
• Syllable scoring appears to be a more sensitive measure for differentiating children with and without Auditory Processing Disorder.
• These findings suggest syllable scoring should be considered for improved diagnostic accuracy in APD evaluations.
