Abstract
A method of recognizing correspondence between a pre-recorded sample announcement and the identical pre-recorded reference announcement is shown. The reference pre-recorded sample announcement is characterized in terms of: (1) Start of speech (SP) where the transition from silence to voicing occurs, (2) average frame power (AFP) for each power frame length of a voicing segment of speech (3) silence gap length (SGL), the duration of non-voicing between two consecutive voicing segments and (4) end of speech (EOS). The sample pre-recorded announcement is also characterized in terms of SP, AFP, SGL, and EOS. The SP, AFPs, SGLs, and EOS of the reference pre-recorded announcement is compared with that of the sample pre-recorded announcement to determine if a match exists.
