Intonations are a crucial tool for our social interactions.

It participates in regulating the dynamics between two speakers, as it embraces the full scope of attitudes a voice can offer. In social settings, our voices can adapt and go from warm to severe, enthusiastic and encouraging to distant and authoritative.

Because expectations exist in social settings, intonations can more or less fit the demands of the context. When appropriate, it can facilitate intimate connection, prosocial behaviors, and by extension enhance cooperation, problem-solving and commitment.
