Speech is the primary means of communication among people. A speech technology is a technology which is built by speech recognition research. A machine such as a computer can understand what human said even the machine can recognize each speech model so the machine can differentiate each human's speech.

A general of speech research topics can be seen in the following figure:
To convert speech to text, we should understand about speech recognition. Otherwise, if we want to generate speech sounds from text, we should learn about speech synthesis. This book doesn't cover about speech recognition and speech synthesis in heavy mathematics and statistics approach. I recommend you read textbook related to those topics.
In this chapter, we will learn how to work sound and speech processing...
