I made a mistake
I recorded my voice with apogee ad sampleratesetting 44.1
but the project was 48k and I locked my audio card also 48k
and when I recorded my voice I feelt strangely that the tempo was very slow
and I found that i made a mistake like above

but I only have to down the pitch..
the tempo is now works fine...
but the pitch is more high by about less 2 semitones
I must down the pith by about the same amount (less 2 semitones)
how much should I down the pitch?
