When will my voice change?

Question:

When will my voice change? I am 12 years old and I hit puberty around the age of 10. I am in the middle of my growth spurt. I grew almost 4 inches in the past year and I am in Tanner stage 3. Do you know when my voice will change?

Thanks.

Answer:

The male voice typically changes during stage 4. Since each stage lasts about two years, you should be noticing a change in your voice in the next two years, which takes you to the middle of stage 4.
