Insubstantial Voice

Here's the problem:
My voice doesn't suit my needs
I need to be loud, to be heard
People need to see when I'm angry
but it you heard my voice you'd ignore me in a second.
I'm tired of having an insubstantial voice
I don't even recognoze it
I've spent my life with this voice and I still can't recognize when it's me talking.
The first thing she told me was that my voice was unexpected
and she never listened to me when I tried to say
it's over, insubstantial voice.
I'll sew a trumpet to my face instead.
