Is this possible?

[NoName11]

Hello, i'm using voxal on skype. All good with my voice but the person on the end of the line says that his voice is transformed, like it's not his real voice. Is that possible, the program modify the voice of the other person?

Hi NoName11,

  From technical perspective, that isn't possible. My initial guess is that the other person's voice is echoed to your microphone through your speakers then it is modified and sent back to other line. If you are using speakers instead of a headphone, while talking, voice output might be echoing back to the your microphone.

Regards,

No, i'm using headphones with microphone not speakers. I really don't understand what it might cause this problem.
