I'm looking to change the gender of a voice, man to woman and vice versa, preferably on linux. I can change the pitch, but it mostly makes the audio just sound chipmunky.

What are the other things that make a voice gender specific? How can I change them?

I have tried soundtouch, sox and LADSPA/Autotalent. Like I said, the main problem is the high pitch for a man->woman just sounds chipmunky. Anyone have success with this before?

I'm looking to add this into Freeswitch, so a C API is preferable, but I can fallback to a pipe.

  • Lol this question is going to hell. – Mulan Oct 15 '15 at 16:45
  • Yeah I have a bad habit of starting off questions broad and then fine tuning them. – Matt Williamson Oct 15 '15 at 16:46
  • No I mean it's totally off-topic and people are going to burn it. You have 14k reputation so I'm sure you're already aware of this. – Mulan Oct 15 '15 at 16:47
  • Off topic of what? This is SO, not some other site from stack exchange. – Matt Williamson Oct 15 '15 at 16:49

  • Read http://stackoverflow.com/help/on-topic. Your question has nothing to do with programming and neither does that other question lol. How about the audio engineering site, http://sound.stackexchange.com/ ? – Mulan Oct 15 '15 at 17:15
  • I understand where you are coming from, but I think it's a lack of domain knowledge on your part or a lack of description on my part. ```LADSPA is an acronym for Linux Audio Developer's Simple Plugin API. It is an application programming interface (API) standard for handling audio filters and audio signal processing effects, licensed under the GNU Lesser General Public License (LGPL).``` – Matt Williamson Oct 15 '15 at 18:39
  • But thank you for pointing out sound.stackexchange. – Matt Williamson Oct 15 '15 at 18:40
  • Another indication would've been you had to create the `ladspa` tag when you asked this question. Yw re: sound.stackexchange – Mulan Oct 15 '15 at 18:57
  • Possibly also ]dsp.stackexhange.com] would be a good place to ask. – marko Oct 15 '15 at 22:41
  • This is a good question! Do you have an input example, and could you put the chipmunky-maker command line? – JJoao Oct 22 '15 at 16:35

Actually, I am not going to give command line answer for this Question, but I found that Audacity does the trick. I mean, if Audacity use VST as its plugin base, .. we will be in luck! I am going to update my finding here

https://audacity.wonderhowto.com/how-to/change-pitch-formant-your-voice-with-audacity-335544/

Okay, it uses VST, https://wiki.audacityteam.org/wiki/VST_Plug-ins#VST_support_in_Audacity

Looking to find that specific plugin to change the pitch/gender voice
