the most common processing approach in the time or space domain is enhancement of the input signal through a method called filtering. digital filtering generally consists of some linear transformation of a number of surrounding samples around the current sample of the input or output signal. there are various ways to characterize filters; for example:
speech processing is the study of speech signals and the processing methods of signals. the signals are usually processed in a digital representation, so speech processing can be regarded as a special case of digital signal processing, applied to speech signals.aspects of speech processing includes the acquisition, manipulation, storage, transfer and output of speech signals.
