Hi there,
Let me know if you already have a website in which you want to include voice modulation or I have to develop a new website from the scratch using that feature because I can see your shared link [login to view URL] is not working properly.
On your website User can record their voice and modulate them from male voice to female voice and vice versa. For that, they have to use microphone feature to record their voices.
This can be doable in Drupal website using a module similar like VoiceCommander which is available on Drupal 7.
You said that anonymous users can't be able to use that feature, So my question is any login or payment is mandatory to do the modulation work on your website?
Please let me know your requirement in detail initiating a CHAT. It seems quite interesting to me and I want to be a part of this job.
You may have a look at my design portfolio:

Looking forward to get your precious response.
