This is a voice changer and talking device. If there is extra noise when you speak and your voice cannot be heard clearly, you can use this to remove the noise while speaking, and people nearby will not notice. It features seven different voice systems: original voice, male voice, female voice, baby voice, and you can add sound effects while speaking. You can connect it to your mobile phone and talk using seven changed voices. The product is completely new. Contact us if you need it.
