Intellivision:List of Intellivoice Games

Released in 1982, the Intellivoice was an Intellivision add-on which added voice synthesis to a select number of games. Although Mattel had high hopes for the module, sales were fairly sluggish and only a literal handful of games were ever released. While most of these games do not necessarily require the Intellivoice to function, they are extremely difficult to play without it as the games used the add-on to provide directions or hints to the player.
