This is the voice that everyone tried (and failed miserably) to mimic after watching Tom Hardy as Bane in Dark Knight Rises (2012). It should be scary and intimidating, but more often than not, a rough voice sound attractive to the audience.
The gritty, textured nature of a rough voice makes it sound commanding, as though intoxicated by power. The rough voice does not falter when faced by hardships and usually leaves a bold impression. It is the voice you expect a smoker to have; heavy and raspy, yet appealing to listen to.
This is the voice favored by supervillain characters in animations. When used in an imposing manner, the rough voice can also be used in films, audiobooks, or plays to showcase a daunting and dangerous character. A softer, less imposing use of the voice can be used by a character to try and get sympathy from the audience or other characters. A rough voice can also occur as a result of overstrained vocal chords. Singers and voice talents who push themselves too hard might have a rough voice.
The rough voice usually has a low pitch. It sounds raspy, strained, and hoarse, almost like there is a scratchiness in the speaker’s throat. It can sometimes sound unnatural but audiences love it.
Using a rough voice when it does not come naturally to you over a long period of time causes a feeling of irritation and slight pain on your vocal cords.
