What is preprocessing in signal processing?

Preprocessing: This stage includes artifact (such as ECG, EOG, and EMG) removal, noise filtering, and resampling the signal to comply with detector input specifications. A low pass filter along with an artifact removal algorithm using adaptive signal processing techniques were implemented for this purpose [4].

What is pre processing in speech recognition?

Speech signal preprocessing is the first and the most important step in the automatic speech recognition process. The preprocessing of speech consists of cleaning the speech signal from ambient and undesirable noises, detecting speech activity, and normalizing the length of the vocal tract.

What is speech signal processing?

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.

What is Speech Processing in NLP?

Natural language processing (NLP) refers to the branch of computer science—and more specifically, the branch of artificial intelligence or AI—concerned with giving computers the ability to understand text and spoken words in much the same way human beings can.
