A new study from Abertay University has revealed that the human brain can rapidly learn to recognize and prioritize a new voice as its own. The findings, published in the British Journal of Psychology, could have significant implications for assistive speech technologies and digital self-representation.
The Study and Key Findings
The research aimed to investigate how our brains process both our natural voices and unfamiliar recorded voices assigned to us. Participants were exposed to a new voice they were instructed to consider as their own and asked to listen for words spoken by that voice, as well as those labeled as belonging to a “stranger” or “friend.”
Even after minimal exposure, participants quickly became adept at recognizing the assigned voice, indicating that their brain had taken ownership of it. In a second phase of the study, participants’ actual voices were introduced into the task, and results showed that their own voices were still identified the fastest.
Potential Applications
Dr. Neil Kirk, who led the research, highlighted that the study’s findings could be beneficial for a range of applications, including voice-assisted technologies for individuals with speech impairments.
“With the recent rise in voice cloning tools powered by artificial intelligence, our work suggests there may be benefits to using a person’s own voice in digital technologies designed to enhance self-representation,” he said. “For example, there could be potential uses in assistive devices for people who have lost the ability to speak or in interactive entertainment with custom online avatars.”
Broader Implications
Professor Sheila Cunningham, a collaborator on the project, noted the study’s relevance to how individuals perceive and prioritize voices. “We know that our brains give special attention to information that relates to ourselves, like hearing our own name in a noisy room. These results show that this prioritization can extend to new voices that we associate with ourselves, demonstrating how adaptable our sense of self can be.”
The study opens the door for further research into how the brain adopts new voices in digital environments, which could influence the development of virtual assistants, gaming experiences, and therapeutic interventions.
