ABSTRACT
In established speech, voice on the one hand and articulation on the other are interdependent units, each of which follows its peculiar rules. Voice is produced by the larynx, the ‘voice box’ which may for the present purpose–certainly not for any other, such as the biological be regarded as a musical instrument. In sound waves the maximum distance from the horizontal zero line which the curve reaches, i.e. its amplitude, indicates the degree of loudness which our ear experiences in a given sound. Sound waves may be reflected on striking walls in the same way as are the ripples on reaching the edges of the pond. If the walls are curved, the reflected waves may be brought to a focal point, and this increases their intensity. If the sound waves do not resound in the cavities of the throat and mouth, the voice makes the impression of being very poor and squeaky.
