Autistic Traits are Linked to Individual Differences in Familiar Voice Identification.
More social-communication autistic traits predict worse recognition of friends’ and family members’ voices in typical teens.
01Research in Context
What this study did
Amaral et al. (2019) asked typical teens to pick out the voices of friends and family.
They also gave each teen a short quiz that measures autistic traits.
The goal was to see if higher trait scores matched worse voice recognition.
What they found
Teens with more social-communication traits were worse at naming who was talking.
The link stayed even when the voices were very familiar.
Other trait areas, like attention to detail, did not matter.
How this fits with other research
Bothe et al. (2019) saw the same pattern with faces: social traits predicted poorer emotion reading.
Turbett et al. (2022) also found that higher traits blurred face identity, showing the effect is not just for voices.
Ruiz Callejo et al. (2023) moved from traits to diagnosed teens and found similar speech-in-noise problems, proving the lab result holds in the clinic.
Why it matters
If a teen misses social cues, check voice and face recognition before you teach conversation skills. A quick voice-ID game can flag who needs extra help. Pair that with face training used in Ellen and Kaitlyn’s work to build a full social-perception package.

03Original abstract
Autistic traits vary across the general population, and are linked with face recognition ability. Here we investigated potential links between autistic traits and voice recognition ability for personally familiar voices in a group of 30 listeners (15 female, 16-19 years) from the same local school. Autistic traits (particularly those related to communication and social interaction) were negatively correlated with voice recognition, such that more autistic traits were associated with fewer familiar voices identified and less ability to discriminate familiar from unfamiliar voices. In addition, our results suggest enhanced accessibility of personal semantic information in women compared to men. Overall, this study establishes a detailed pattern of relationships between voice identification performance and autistic traits in the general population.
