Primary Outcome Measures

Name	Time	Method
To show that acoustic changes in the spectral and temporal characteristics of speech (e.g., change in formant frequency or voice onset time) can be measured acoustically at the eardrum. a probe microphone and real ear measurement system will be used to record the sound at the ear drum.[ This will be measured at the time of the research appointment, immediately prior to the measurement of the cortical evoked potentials (CAEPs)]

Secondary Outcome Measures

Name	Time	Method
To show that acoustical changes in speech sounds measured at the eardrum correlate with changes in the speech-evoked cortical auditory evoked potentials (CAEP). the CAEP will be measured via surface electrodes on the scalp[ the speech-evoked cortical auditory evoked potentials (CAEP) will be measured at the time of the research appointment]
