Editing Voice acting (section)

===Automated announcements===
Voice artists are also used to record the individual sample fragments played back by a computer in an automated announcement. At its simplest, each recording consists of a short phrase which is played back when necessary, such as the "[[mind the gap]]" announcement introduced on the [[London Underground]] in 1969, which is currently voiced by [[Emma Clarke]]. In a more complicated system, such as a speaking clock, the announcement is re-assembled from fragments such as "minutes past", "eighteen", and "p.m." For example, the word "twelve" can be used for both "Twelve O'Clock" and "Six Twelve". Automated announcements can also include on-hold messages on phone systems and location-specific announcements in tourist attractions.
