The lips produce the sounds of _p_, _b_, _wh_, and _w_. The lips and
teeth produce the sounds of _f_, _v_. The tongue and teeth together
make the sounds of _th_ and _dh_. The tongue in conjunction with the
forward portion of the hard palate produces several sounds--_t_, _d_,
_s_, _z_, _r_, and _l_. The tongue operating against or near the rear
of the hard palate pronounces _ch_, _j_, _sh_, _zh_, and a different
_r_. To make the consonant _y_ the tongue, the hard palate, and the
soft palate operate. The tongue and soft palate make _k_ and _g_. A
strong breathing makes the sound of _h_. By including the nasal
passages in conjunction with some of the other parts here listed the
so-called nasals, _m_, _n_, and _ng_, are made. According to the organ
involved our consonant sounds are conveniently grouped as labials
(lips), dentals (teeth), linguals (tongue), palatals (palate), and
nasals (nose).

The correct position and action of the vocal organs are of supreme
importance to all speakers. Many an inveterate stammerer, stutterer,
or repeater can be relieved, if not cured, of the embarrassing
impediment by attention to the position of his speech organs and by
careful, persistent practice in their manipulation. In fact every
speaker must be cognizant of the placement of these parts if he
desires to have control over his speech. Frequently it is such correct
placement rather than loud noise or force which carries expressions
clearly to listeners.

While it is true that singing will strengthen the lungs and help in
control of breath, it is not always the fact--as might be
expected--that singing will develop the speaking voice. Not every
person who can sing has a pleasant or forceful voice in ordinary
