Description

The representation of spoken-sentence information in specific regions of the brain is more resistant to interference by competing speech if the target talker is familiar. The posterior temporal cortex represents information about target speech more robustly in the presence of competing speech when the target talker is a friend or partner. We have also shown that the relative robustness of the representations for a familiar, compared to an unfamiliar, voice aligns with the intelligibility benefit that the listener gains from that familiar voice.
