They listen, too. Voice Command cartridges, which will go on sale later this summer, let a player direct the action with spoken directions. Milton Bradley declined to say how many of the cartridges it expects to sell in 1983. In a baseball game demonstrated to wide-eyed toy buyers last week, the player controls the movement of the ball on the screen by a series of statements made into a special microphone. Example: When the words ''first baseman, shortstop, pitcher'' are said, the ball is thrown from the first baseman to the shortstop to the pitcher, who then pitches. With another set of vocal commands, the ballplayers can be renamed. The right fielder, for instance, might become ''Reggie.'' So if the statement ''Reggie, first base'' were made, the right fielder would lob the ball to the first baseman's glove. In another Milton Bradley game, Sewermania, a character must defuse a time bomb in a maze-like sewer filled with ''killer'' rats and alligators. With one voice command (''pick up''), he grabs a shovel. Another order (''kill'') prods the shovel-armed man to bash the rats. Despite the technological advances represented by the Voice Command cartridges - the voice recognition feature is controlled by a single integrated-circuit chip - playing the new games is going to be expensive. The cartridges must be plugged into a special $100 microcomputer device made by Milton Bradley. The Expander, as it is called, can be used only if it is attached to a Texas Instruments 99/4A Home Computer ($147). The cartridges will run about $30 each.
