What is yakback?

Yakback is a toy microphone that records audio and allows playback with different voice effects. It was first introduced in the 1990s and gained popularity as a fun and entertaining gadget. Yakback has three buttons - record, play, and change voice - which allow you to record your voice and play it back with different tonal and pitch variations. It can also play pre-recorded sound effects and phrases. Yakback was mainly marketed towards children, but people of all ages enjoyed playing with it. It has since been discontinued, but similar voice-changing toys are still available in the market today.
