Another use for voice fonts is in electronic music. A commonly available set of synthetic voices from Macintosh computers can be used to enhance the mood of certain music pieces that need a voice but where the composer feels that providing a human voice is not in their interests. Here, male voices can be combined in a choir to provide the tenor and bass for a particular piece, and female voices can be added to fill in other parts of the ensemble—resulting in a choir that consists of speech synthesis rather than human singers, or to utilize a female voice when none are available.
