LING 1100 Lecture Notes - Lecture 8: Spectrogram, Diphone, Speech Synthesis
Document Summary
Computational linguistics computational linguistics is the study of computer processing, understanding and generation of human language. It is a subfield of artificial intelligence ai. Human language systems and computers are both information processing systems. Modelling language computationally may give insights into how humans process language. Sometimes considered to be the father of computer intelligence. Judge listen to a human and a computer. Prize: gold me del and us,000 for the first computer whose response are indistinguishable from a humans every year: a smaller prize for the best entry. First year 1991, winner: therapist iii, based on eliza. Speech synthesis : concatenative synthesis: strings together segments of recorded speech diphone synthesis: uses a small recoded database containing all the diphones (transitions between two sounds) of a language. English: over 1400 diphones, spanish: 800 german 1800. Unit selection synthesis: uses recordings of one or many of all possible types: sounds, diphones, syllables, words .
