Understanding How Aging Affects Speech

Understanding How Aging Affects Speech

This protocol includes studies on how aging affects the control and coordination of speech production. Various hypotheses are being investigated in our laboratory with the common aim of improving our understanding of the processes and mechanisms underlying normal and disordered speech.

The common procedure across these studies consists of recording the participants’ speech utterances acoustically (i.e., recording the speech output with a microphone) and making acoustic measures from the obtained recordings. In some studies, the participants wear insert earphones through which they can hear their own speech and this feedback signal may be altered to study the role of auditory feedback in speech production.

We are recruiting older adults for a wide variety of experiments. All of our research study participants will be compensated $20/hr for their time, in addition to receiving a free hearing screening as part of the study. Additionally, we can reimburse for parking as needed.
