II. Besides improper modes of spelling, there is another way of concealing the true nature of sounds. If I say that ka and ga are allied, the alliance is manifest; since I compare the actual sounds. If I say ka and gee are allied, the alliance is concealed; since I compare, not the actual sounds, but only the names of the letters that express those sounds. Now in the English language we have, amongst others, the following names of letters that have a tendency to mislead:—
The sounds fa and va are allied. The names eff and vee conceal this alliance.
The sounds sa and za are allied. The names ess and zed conceal the alliance.
In comparing sounds it is advisable to have nothing to do either with letters or names of letters. Compare the sounds themselves.
In many cases it is sufficient, in comparing consonants, to compare syllables that contain those consonants; e.g., to determine the relations of p, b, f, v, we say pa, ba, fa, va; or for those of s and z, we say sa, za. Here we compare syllables, each consonant being followed by a vowel. At times this is insufficient. We are often obliged to isolate the consonant from its vowel, and bring our organs to utter (or half utter) imperfect sounds of p', b', t', d'. In doing this we isolate the consonant.
[§ 197]. Let any of the vowels (for instance, the a in father) be sounded. The lips, the tongue, and the parts within the throat remain in the same position: and as long as these remain in the same position the sound is that of the vowel under consideration. Let, however, a change take place in the position of the organs of sound; let, for instance, the lips be closed, or the tongue be applied to the front part of the mouth: in that case the vowel sound is cut short. It undergoes a change. It terminates in a sound that is different, according to the state of those organs whereof the position has been changed. If, on the vowel in question, the lips be closed, there then arises an imperfect sound of b or p. If, on the other hand, the tongue be applied to the front teeth, or to the fore part of the palate, the sound is one (more or less imperfect) of t or d. This fact illustrates the difference between the vowels and the consonants. It may be verified by pronouncing the a in fate, ee in feet, oo in book, o in note, &c.
It is a further condition in the formation of a vowel sound, that the passage of the breath be uninterrupted. In the sound of the l' in lo (isolated from its vowel) the sound is as continuous as it is with the a in fate. Between, however, the consonant l and the vowel a there is this difference: with a, the passage of the breath is uninterrupted; with l, the tongue is applied to the palate, breaking or arresting the passage of the breath.
[§ 198]. The primary division of our articulate sounds is into vowels and consonants. The latter are again divided into liquids (l, m, n, r) and mutes (p, b, f, v, t, d, g, s, z, &c.) Definitions for the different sorts of articulate sounds have still to be laid down. In place of these, we have general assertions concerning the properties and qualities of the respective classes. Concerning the consonants as a class, we may predicate one thing concerning the liquids, and concerning the mutes, another. What the nature of these assertions is, will be seen after the explanation of certain terms.
[§ 199]. Sharp and flat.—Take the sounds of p, f, t, k, s; isolate them from their vowels, and pronounce them. The sound is the sound of a whisper.
