Answer:
1. Amplify sound --- Resonators
2. Divide sound into words and syllables --- Articulators
3. One's tone of voice --- Pitch
4. Stage whisper --- Sotto voce
5. Habitually shrill voice quality --- Stridency
Step-by-step explanation:
1- Resonators are devices whose function is to amplify the wave of sound, so that it expands and, therefore, the sound is heard louder.
2- Articulators are those parts of the body that are used in the formation of speech sounds.
3- The pitch in music is the quality that differentiates a high-tone sound from a low sound. It depends on the frequency of the sound, which determines the name of the notes.
4- Sotto voce means intentionally lowering the voice to emphasize. In music, sotto voce is a dramatic decrease in the volume of the voice or an instrument.
5- It is called strident to the sound that is sharp, unpleasant and squeaky.
