matlab - making pink noise (1/f) using list of frequencies

making pink noise (1/f) using list of frequencies

I would like to see what type of noise I would get if I used just the frequency in my voice. I created a matlab array using fft to get the [frequency,amplitude,phase] to reproduce my vocal signal.

I would like to take this file/data and use it to create pink noise (1/f). Of course when I use 1/f for the frequency the numbers become very small does anyone have any ideas how to use my own vocal frequencies that I get from doing a fft in matlab from my voice to create pink noise (1/f).

Thanks
