ARTICULATION TESTING METHODS 853 



spondence between all of these measured quantities for all types of 

 speech distortion. The data entering into the sound, vowel, conso- 

 nant, and syllable articulation curves were very extensive with respect 

 to types of distortion and testing personnel. The theoretical equations 

 relating them seem to rest upon assumptions with few uncertainties. 

 For these reasons, it is felt that these relations can be used with 

 considerable confidence, especially for values of syllable articulation 

 greater than 30 per cent. The curves dealing with English words 

 and sentences are based upon less diversified data and should be 

 regarded as indicative only of the correlation and the type of relation. 

 During the past few years articulation testing methods have been 

 used more and more, both in this country and abroad. It is felt that 

 in order to compare the results obtained by various crews in various 

 tongues, it is desirable to use techniques that operate on the same basic 

 principles and to calibrate various creivs on similar reference circuits.
