Abstract of CA2452022
|
| An apparatus for changing the
playback rate of recorded speech includes memory storing a
plurality of recorded speech messages and a plurality of feature
tables. Each feature table is associated with an individual one
of the speech messages and includes speech frame parameters
based on the fitter states of speech frames of the associated
recorded speech message. A playback module receives input
specifying a recorded speech message in the memory to be played
and the rate at which the recorded speech message is to be
played back. In response to the input, the playback module uses
a set of decision rules to modify the specified speech message
based on the speech frame parameters in the feature table
associated with the specified speech message and the specified
playback rate, prior to playing back the specified speech
message. |
