Herbie Hancock’s Electronic Instrument Glossary

Voice Bag – The voice bag or talk box is a device that makes a synthesizer talk. The musician sends a note from their instrument into the voice bag. The voice bag then sends that same note through a plastic tube into the musician’s mouth. Using their mouth, throat, and larynx, the musician shapes that sound to make the sound talk. This instrument was used by Wah Wah Watson on the 1975 album Man-Child.
