Size of the vocabulary − Size of the vocabulary impacts the ease of developing an ASR. The difficulty of speech recognition technology can be broadly characterized along a number of dimensions as discussed below −

Difficulties in developing a speech recognition systemĭeveloping a high quality speech recognition system is really a difficult problem. However, it is not quite easy to build a speech recognizer. Without ASR, it is not possible to imagine a cognitive robot interacting with a human. Speech Recognition or Automatic Speech Recognition (ASR) is the center of attention for AI projects like robotics. Remember that the speech signals are captured with the help of a microphone and then it has to be understood by the system. This chapter focuses on speech recognition, the process of understanding the words that are spoken by human beings. Third, speech synthesis to allow the machine to speak. Second, natural language processing to allow the machine to understand what we speak, and Speech processing system has mainly three tasks −įirst, speech recognition that allows the machine to catch the words, phrases and sentences we speak The basic goal of speech processing is to provide an interaction between a human and a machine. Speech is the most basic means of adult human communication.


In this chapter, we will learn about speech recognition using AI with Python.
