The scientific study of speech sounds began with Hclmholtz, who 

 also made a fundamental study of hearing. Hclmholtz had the 

 advantage, in approaching the.se problems, of a knowledge of physiology 

 as well as a mastery of theoretical physics. With this equipment 

 and such simple laboratory apparatus as he created, he did his great 

 work on speech and hearing of which we have the record (in English 

 translation) under the title of "Sensations of Tone." ' Today, with
