Speech Perception Lab
Dr. Dan Fogerty
Our work examines speech perception in adverse
listening conditions by looking at the following domains:
• Acoustic phonetics
• Speech and language disorders
• Speech and noise interactions
• Age-related factors
• Hearing loss and amplification
• Multimodal perception
• Perceptual and cognitive factors that maximize speech
recognition

19. The Contribution of Extended High
Frequencies to Speech/Voice Perception
Auditory Neurodevelopment of
Preterm Infant
Auditory Neuro Experience Lab
Dr. Brian Monson
• Goal of this research:
• Develop interventions that will optimize
auditory experience for preterm infants to
• Promote healthy auditory brain
development, speech perception, and
language acquisition during infancy and
childhood.
• Extended high-frequency energy (energy
produced at frequencies >8 kHz) provides
the auditory brain with useful information
for speech and singing voice perception
• Cues for speech source location,
speech/voice quality, vocal timbre,
and even speech intelligibility.
• These cues are likely utilized more readily
by children, who typically have much more
sensitive high-frequency hearing than
adults.
