 In the 2000s, the increasing use of recording software which contains vocal processing algorithms and digital pitch correction devices is replacing some of the roles of the vocal coach.In the 1970s, if a producer wanted to record a single with a popular sports star with few vocal skills, the celebrity would need weeks of vocal coaching to learn their song and improve their tone and diction.In the 2000s, the vocals are often processed through pitch correction software instead, and rhythm can be corrected with Pro Tools.
