The document discusses the importance of a teacher's voice in the classroom. It identifies three key issues to consider regarding voice use: audibility, variety, and conservation. For audibility, the teacher's voice must be loud enough for all students to hear and effective in different situations. For variety, the teacher should adjust voice tone, volume, pace, pitch, and modulation based on the lesson. For conservation, teachers need to properly breathe and avoid straining their voices to conserve their voice over the course of a day or week.

3. Audibility
 Teachers need to have audibility; they
must be sure that all students can hear
them.
 Teachers’ voice need to be effective in a
variety of circumstances.
 Audibility and voice quality should always
go together.

4. Variety
 When the students
are distracted, the
teachers have to use
suitable voice tone
(do not necessary
have to shout) to
make themselves
understood and
catch their
attention.

5. Variety
 Teachers have to vary the quality of
their voices according to the type of
lesson or activity.
o Volume: how long or softly teachers
speak
o Pace: how teacher use pausing
(quickly or slowly)
o Pith: how high or low is
teacher's voice range go
o Modulation: how teachers
adjust the tone of their voice.

6. Conservation
 Conserving the voice is one of the things teachers
should take into account when planning a day's or
a week's work.
 It is important that teachers breathe correctly so
that they do not strain their larynxes.
