|Exploring the tonal accuracy of the player’s voiced input.|
Some games focus on the player's ability to provide an input whose pitch matches that of a pre-defined sound piece such as a song. This is typically done through the input of voice, with the player singing the lyrics of a selected song. Since pitch is the acoustic parameter being considered, the exact wording of the player's input is usually secondary to the performance.
