Computer-based voice familiarisation improves speech intelligibility for older and younger adults

Understanding speech in noisy environments is often challenging, but is much easier if we are listening to someone familiar—for example, naturally familiar people (e.g., friends and partners) or voices that have been familiarised artificially in the lab. Thus, familiarising people with voices they regularly encounter (e.g., new friends and colleagues) could potentially improve speech intelligibility in everyday life—which might be particularly useful for people who struggle to comprehend speech in noisy environments, such as older adults. Yet, we do not currently understand whether computer-based voice familiarisation is effective when delivered outside of a lab setting, and whether it is effective for older adults. Here, in an online computer-based study, we examined whether learned voices were more intelligible than novel, unfamiliar voices. We compared 20 older (55–73 years) and 20 younger (18–34 years) adults. Both groups benefited from voice familiarisation training, and the magnitude of the intelligibility benefit was similar between the older and younger groups. These findings demonstrate that older adults can learn new voices as effectively as younger participants for improving speech intelligibility, even given a relatively short (< 1 hour) duration of familiarisation that is delivered in the comfort of their own homes.

How Long Does It Take for a Voice to Become Familiar? Speech Intelligibility and Voice Recognition Are Differentially Sensitive to Voice Training

When people listen to speech in noisy places, they can understand more words spoken by someone familiar, such as a friend or partner, than someone unfamiliar. Yet we know little about how voice familiarity develops over time. We exposed participants ( N = 50) to three voices for different lengths of time (speaking 88, 166, or 478 sentences during familiarization and training). These previously heard voices were recognizable and more intelligible when presented with a competing talker than novel voices—even the voice previously heard for the shortest duration. However, recognition and intelligibility improved at different rates with longer exposures. Whereas recognition was similar for all previously heard voices, intelligibility was best for the voice that had been heard most extensively. The speech-intelligibility benefit for the most extensively heard voice (10%–15%) is as large as that reported for voices that are naturally very familiar (friends and spouses)—demonstrating that the intelligibility of a voice can be improved substantially after only an hour of training.

Spatial selective auditory attention is preserved in older age but is degraded by peripheral hearing loss

Interest in how ageing affects attention is long-standing, although interactions between sensory and attentional processing in older age have not been systematically studied. Here, we examined interactions between peripheral hearing and selective attention in a spatialised cocktail party listening paradigm, in which three talkers spoke different sentences simultaneously and participants were asked to report the sentence spoken by a talker at a particular location. By comparing a sample of older (N = 61; age = 55– 80 years) and younger (N = 58; age = 18–35 years) adults, we show that, as a group, older adults benefit as much as younger adults from preparatory spatial attention. Although, for older adults, this benefit significantly reduces with greater age-related hearing loss. These results demonstrate that older adults without hearing loss retain the ability to direct spatial selective attention, but this ability deteriorates with age-related hearing loss. Thus, reductions in spatial selective attention likely contribute to difficulties communicating in social settings for older adults with age-related hearing loss. Overall, these findings demonstrate a relationship between mild perceptual decline and attention in older age.
