You can alter your voice to be silly, either a higher pitch or a deeper one.
Children can find this rather amusing or scary.
Being able to talk and breathe
You voice changes slightly. It also sounds silly and fake. Handy for children’s parties or stupid impressions.
The voice you choose, either higher or lower, does not sound like a normal voice. Trying to use this feat in a situation where you do not wish for your normal voice to be recognised, will actually make you MORE memorable, as the voice is rather distinctive.
