Despite positive outcomes from treatment studies, concerns remain that the complex and abstract nature of spectrograms may make these speech trainingaids unsuitable for use with children. This investigation examined how well children with normal hearing sensitivity and children with impaired hearing can recognize spectrographic cues for vowels and consonants, and the ages at which these visual cues are distinguished. Sixty children (30 with normal hearing sensitivity, 30 with hearing impairments) in 3 age groups (6–7, 8–9, and 10–11 years) were familiarized with the spectrographiccharacteristics...
