to the variations in the size of the vibrations when vowels were 

 pronounced on different pitches of the voice. 



Xumerous lantern -sUdes illustrating kjmographic tracings were 

 then shown. Some of these tracings are reproduced in Figs. 11 to 15. 

 Such tracings are chiefly useful (1) for detecting the presence or 

 absence of voice ; (2) for detecting the presence or absence of 

 nasality ; (3) for measuring the lengths of sounds ; and (4) for 

 calculating the pitch of the voice.]

Note the differences in the nose-tracings. 



The above examples show to what extent experimental phonetics 

 may be useful to the language learner. It furnishes him with much 

 of the information he wants in regard to pronunciation. The practical 

 linguist should make these ascertained facts the basis of his study of 

 the pronunciation of the language he is learning. He will be able to 

 infer from them how he must proceed in order to get his own organs 

 of speech to perform the movements required by the foreign language. 



In conclusion, it may be as well to point out that as these 

 scientific methods of analysis are useful to the linguist, so also the
