[Wikipedia excerpt: ‘…Talking tape (also known as talkie tapes, talking strips) is a analog plastic groove medium that is used to store short snippets of sound. The device physically resembles zip ties: one side of a thin plastic strip has a series of ridges and the other side is flat. Sound is recreated by running a fingernail over the grooved side of the strip while one end is held against an amplifier such as a paper card, balloon, foam cup, or desk. The medium works on a similar principle to gramophone records, using grooves to store sound albeit in a linear manner opposed to a spiral. The tapes come pre-moulded and there is no easy way to record sound in the format without special machinery. .…..’ ].
