Vowels and Consonants pdf epub mobi txt 电子书 下载 2026

This popular and accessible introduction to phonetics is now available in a fully updated second edition. Peter Ladefoged describes how languages use a variety of different sounds, many of them quite unlike any that occur in well-known languages.

Important topics covered in Vowels and Consonants include:

* The main forces operating on the sounds of languages

* The acoustic components of speech and speech synthesis

* Computers and Text-To-Speech systems and speech recognition systems

* Descriptions of the sounds of a wide variety of languages that are reproduced on the accompanying CD.

This revised edition includes a new chapter on how we listen to speech and the greatly expanded CD now contains data on 100 languages to reinforce learning and bring the descriptions to life.
