The time alignment algorithm is very simple and
straightforward. To explain this algorithm, consider the
following A Simple Time Alignment Algorithm for Spoken
digit . parameters: (number of) considered frames (CF), start
point (SP), and end point (EP). These parameters must be
adjusted before running the algorithm. CF should take only
positive integer greater than 2, while SP and EP should take
values between 0 and 1 inclusive. CF is the number of
frames that would be considered by the time alignment
algorithm and the rest of utterance’s frames are totally
ignored.
