In her Introduction, Carla Mereu Keating sets off by clarifying the aim of her book –
doppiaggio, the Italian word meaning a post-synchronisation technique that can be
either an intralingual or interlingual practice. She also elicits the difference between
voice-over (or partial) dubbing and total dubbing, which some authors (e.g.
Shuttleworht and Cowie, 1997) refer to as revoicing — partial revoicing or voice-over
and total revoicing or dubbing. When speaking of dubbing, it is imperative to make a
parallel with subtitling, since historically speaking these were the two modes of election
from the 1930s onwards mainly in Europe. Nonetheless, Mereu Keating also mentions
the more recent accessibility modes of subtitling for the deaf and hard of hearing and
audiodescription, along with their most prominent scholars, such as Díaz Cintas, Orero
and Remael (2007).
