Speech an Acquired Ability. We frequently regard and discuss speech as a perfectly natural attribute of all human beings. In some sense it is. Yet an American child left to the care of deaf-mutes, never hearing the speech of his own kind, would not develop into a speaker of the native language of his parents. He doubtless would be able to imitate every natural sound he might hear. He could reproduce the cry or utterance of every animal or bird he had ever heard. But he would no more speak English naturally than he would Arabic. In this sense, language is not a natural attribute as is hunger. It is an imitative accomplishment acquired only after long years of patient practice and arduous effort. Some people never really attain a facile mastery of the means of communication. Some mature men and women are no more advanced in the use of speech than children of ten or fifteen. The practice is life-long. The effort is unceasing.
A child seems to be as well adapted to learning one language as another. There may be certain physical formations or powers inherited from a race which predispose the easier mastery of a language, but even these handicaps for learning a different tongue can be overcome by imitation, study, and practice. Any child can be taught an alien tongue through constant companionship of nurse or governess. The second generation of immigrants to this country learns our speech even while it may continue the tongue of the native land. The third generation—if it mix continuously with speakers of English—relinquishes entirely the exercise of the mother tongue. The succeeding generation seldom can speak it, frequently cannot even understand it.
Training to Acquire Speech Ability. The methods by which older persons may improve their ability to speak are analogous to those just suggested as operative for children, except that the more mature the person the wider is his range of models to imitate, of examples from which to make deductions; the more resources he has within himself and about him for self-development and improvement. A child’s vocabulary increases rapidly through new experiences. A mature person can create new surroundings. He can deliberately widen his horizon either by reading or association. The child is mentally alert. A man can keep himself intellectually alert. A child delights in his use of his powers of expression. A man can easily make his intercourse a source of delight to himself and to all with whom he comes in contact. A child’s imagination is kept stimulated continually. A man can consciously stimulate either his imagination or his reason. In the democracy of childhood the ability to impress companions depends to a great extent upon the ability to speak. There is no necessity of following the parallel any farther.
