sound-alike

A sound alike is a person who is able to use their voice to closely resemble that of another person.

A sound-alike is a recording intended to imitate the sound of a popular record, the style of a popular recording artist, or a current musical trend; the term also refers to the artists who perform on such recordings. In the voice-over world, it may also refer to those who recreate the voice and vocal mannerisms of a given celebrity's vocal performance (see also impersonator).
