Types of Automated Speech Recognition

  • Direct Dialogue Conversations :
    • It's a basic version of ASR. It consists of machine interface which connects with people. You're required to verbally interact with the computer; the machine tells you to respond with a selected word from a list of words and accordingly, provides response or answer to your request. Automated telephone banking uses this technology to enable customers perform a wide range of financial transactions over the telephone.
  • Natural Language Conversation :
    • It's a more advanced and sophisticated version of ASR. It understands the user's speech or writing and responds to the user on the idea of understood content. It enables people to interact with computer using everyday language.

How ASR works

  • The basic sequence of events that exists in ASR is as follows:
    • A person speaks to the software using an input device like a microphone.
    • The data input device creates a wave file of your words.
    • The volume of wave file is normalized and background noises are removed.
    • The cleaned wave file is broken down into phonemes which are the smallest units of sound. There are around 44 phonemes in English.
    • The ASR software analyzes the phonemes, ranging from the primary phoneme. It uses statistical probability analysis to work out whole words before making an entire sentence.
    • Now, after understanding the words, the ASR responds in a meaningful way.
