7. Computational linguistics

an approach to linguistics which uses mathematical techniques, often with the aid

of a computer. Computational linguistics includes the analysis of language data,

e.g. in order to establish the order in which learners acquire various grammaticalrules or the frequency of occurrence of some particular item. It also includes

research on automatic translation, electronic production of artificial speech

(SPEECH SYNTHESIS) and the automatic recognition of human speech.

Speech synthesis

the automatic synthesis of speech-like sounds by a computer using a speech

synthesizerorvoice synthesizer, such as when a computer takes printed text as

input and produces a spoken version of it. Many of the recorded messages heard

on the telephone are not natural language but are produced by speech synthesis.

Diachronic linguistics

an approach to linguistics which studies how a language changes over a period of

time, for example the change in the sound system of English from Early English to

Modern British English.

Diachronic linguistics has been contrasted with synchronic linguistics which is

the study of a language system at one particular point in time, for example the

sound system of Modern British English.
