Some easily remembered suggestions regarding conversation are these:
1. Pronounce your words distinctly and accurately, like "newly made coins" from the mint, but without pedantry.
2. Upon no occasion allow yourself to indulge in careless or incorrect speech.
3. Open the mouth well in conversation. Much indistinct speech is due to speaking through half-closed teeth.
4. Closely observe your conversation and that of others, to detect faults and to improve your speaking-style.
5. Vary your voice to suit the variety of your thought. A well-modulated voice demands appropriate changes of pitch, force, perspective, and feeling.
6. Avoid loud talking.
7. Take care of the consonants and the vowels will take care of themselves.
8. Cultivate the music of the conversational tones.
9. Favor the low pitches of your voice.
