Speech coders using block-wise coding usually introduce delays. If the length of the speech analysis frame is 25 msec, give a reasonable estimate of the delay on the receiver side.

Question

Quizplus · Accepted Answer

The Answer is The encoder has to wait until a whole frame has been collected before processing; this introduces a

25 \mathrm{~ms}

delay.
Pitch analysis usually needs at least one frame buffering for smoothing. Adding the times for encoding and decoding, the delay is usually

3 *

frame\_size

=75 \mathrm{~ms}

.
