On the Articulation of the Human Voice. 165 
If with sylables beginning and ending with the same consonant 
change of consonant action is made in the pauses, the difficulty of 
pronouncing is further increased, as is felt in pronouncing pip tit 
kik, as compared with pittikkip, so that the form of word most 
readily pronounced is that which changes its consonant action 
during the vowel sounds, and repeats it, or re-acts upon the con- 
sonant in the pauses between the syllables, 
pip tit sik pittikkip. 
When one syllable ends with a vowel and the next begins with 
a consonant, as in 
o-bey, 
the pneumatic action of the consonant is doubled ; and whether 
it is doubled also in the sound conveyed to the hearer depends 
on whether the preparation for the consonant action is made by 
the speaker at, or after, the time that the vowel sound ceases. 
Effects of a corresponding character arise when the first syl- 
lable ends with a consonant and the second begins with a vowel, 
as in 
um-ert. 
Jointing by change of vowel sound, as in vial, duel, flour, or 
flower, &c., is the least distinct of any mode of syllabication. 
The indistinctness arises from the gradual manner in which 
vowel sounds (except when aspirated) commence and terminate. 
The last mode of jointing is by compound consonants. 
The tendency of articulation in this case is to select one of the 
consonant actions which can be doubled consistently with the 
phonetic result, and to make the joint by doubling that con- 
sonant, 
Thus paliry has a tendency to become palt-try, 
sundry % 5 sund-dry, 
ante 7 of ant-te, 
helpless 7 help-pless. 
And this tendency to re-acting upon one consonant is so great 
as to bring about compounds which we are not accustomed to 
consider as such.
