Explanation:

A linguist will study paralanguage, also called "vocalics", to see how emotional information is conveyed through deliberate or not conscious use of some pitch, volume, intonation in the way we speak.

In paralanguage, the non-lexical aspects of speech like the intonation or pauses will further reveal the expressive aspect and emotions that are present in that message.
