Explanation of the Topics (Q.2)

The first topic I am going to explain is “Speech Recognition” which belongs to The Association for Computational Linguistics and Natural Processing Language (Columbus, Ohio).

Speech recognition (also known as automatic speech recognition or computer speech recognition) converts spoken words to machine-readable input (for example, to keypresses, using the binary code for a string of character codes). The term voice recognition may also be used to refer to speech recognition, but more precisely refers to speaker recognition, which attempts to identify the person speaking, as opposed to what is being said.

Speech recognition applications include voice dialing (e.g., “Call home”), call routing (e.g., “I would like to make a collect call”), domotic appliance control and content-based spoken audio search (e.g., find a podcast where particular words were spoken), simple data entry (e.g., entering a credit card number), preparation of structured documents (e.g., a radiology report), speech-to-text processing (e.g., word processors oremails), and in aircraft cockpits (usually termed Direct Voice Input).

The second topic is “Dialogue systems” which belongs to The Association for Computational Linguistics and Natural Processing Language (Columbus, Ohio).

A dialog system is a computer system intended to converse with a human, with a coherent structure. Dialog systems have employed text, speech, graphics, haptics, gestures and other modes for communication on both the input and output channel. An architecture for a typical spoken dialog system is shown in the figure below.

What does and does not constitute a dialog system may be debatable. The typical GUI wizard does engage in some sort of dialog, but it includes very few of the common dialog system components, and dialog state is trivial.

The last topic is “Pragmatics” which belongs to The Association for Computational Linguistics and Natural Processing Language (Columbus, Ohio).

Pragmatics is the study of the ability of natural language speakers to communicate more than that which is explicitly stated. The ability to understand another speaker’s intended meaning is called pragmatic competence. An utterance describing pragmatic function is described as metapragmatic. Another perspective is that pragmatics deals with the ways we reach our goal in communication. Suppose, a person wanted to ask someone else to stop smoking. This can be achieved by using several utterances. The person could simply say, ‘Stop smoking, please!’ which is direct and with clear semantic meaning; alternatively, the person could say, ‘Whew, this room could use an air purifier’ which implies a similar meaning but is indirect and therefore requires pragmatic inference to derive the intended meaning.

Pragmatics is regarded as one of the most challenging aspects for language learners to grasp, and can only truly be learned with experience.
