How voice-changer works: the voice-changer feature uses a pitch modulator to simulate the sound of both masculine and feminine voices. While the voice-changer attempts to change your voice, the pitch of your voice will also dictate the final outcome of how it sounds. For example, if you have a deeper voice and attempt to use the Male Voice-Changer, you may find the difference insignificant.
To use voice-changer, your account must be verified, and you must use the “Select Verified Display Number” option. If you do not choose a verified number, the voice-changer feature will be disabled and will show a faded grey color. Alternatively, it will be highlighted in white when the feature is enabled.
