Talk about appropriate volume levels for the voice in different situations. Discuss how you should use different volumes for scenarios such as a library, a phone conversation and a public performance.
Sit face to face with a child who has trouble speaking loud enough in regular conversations. Tell her that you are going to talk and that she should show you a thumbs up sign if you need to raise the volume of your voice and a thumbs down sign if you need to lower the volume of your voice. Instruct her to let you know when the volume of your voice is just right for conversation. Repeat the exercise but let the child speak as you reflect the appropriate hand signs. Practice this exercise multiple times and advise the child to monitor her own volume during conversations.
Instruct young singers, speakers and actors to stand up straight and tall. Good posture is essential to being able to use the abdominal muscles that support vocal tone.
Tell the children to sing or speak softly at first so that imaginary people in the audience cannot hear them.
Instruct the kids to sing or speak as if they were pushing their voices toward the back wall of the room or auditorium.
Advise kids to visualize their voices coming from their bellies and chests rather than from their throats.
