Determine fundamental frequency of voice recordings

I am using the command line tool aubiopitch to analyze voice recordings. My goal is to determine the fundamental frequency of the voice recorded. I know, of course, that the frequency varies – that's why I want to calculate an "average" in Hz over a 30-second recording.

My question: aubio uses different methods to determine the pitch of a recording: Schmitt trigger, harmonic comb, yin, yinfft etc. Which one of those would be my preferred choice when dealing with pure human voice recordings (no background music, atmo etc.).

I would recommend using yinfast or yinfft (default). For a discussion of the algorithms, their parameters, and their performance, see Chapter 3 of this document.

Note that the median is better suited than the average in this case.

CREPE is good and outperforms many others since it uses advanced neural-network machine learning for pitch prediction. It might be unstable in unseen conditions though and might not be very easy to plug since it requires tensorflow.

For more traditional and lightweight solution oyu can try REAPER.
