Hello avengeline,
Thank you for your interest in my problem!
You are right, my description was quite vage. Let me explain:
I need to develop code for the algorithms I mentioned, so they find the fundamental frequency of a voice signal.
A voice signal (e.g. a word or phrase that I recorded) should be the input of the algorithm and the output should be its fundamental frequency.
The frequency sequence which will be produced by the algorithm will be smoothed by median filter. Once median filter is apllied the average fundamental frequency should be calculated.
