I am a school teacher, but my voice strength is very low and I can't teach loudly, so is there any alternative to increase my voice strength?

I would recommend an evaluation by an Ear, Nose, and Throat physician to rule out the possibility that something structural/ functional is contributing to your low volume. In the absence of anatomic or physiologic abnormality, abnormally low volume can be the result of a functional voice disorder (i.e., how you are using your voice), and can be treated in voice therapy with a speech pathologist who specializes in the treatment of voice disorders.
Good luck to you!
