Seaman

A fish with a human face made players talk to their Dreamcast.

Released for Dreamcast in Japan in 1999, Vivarium’s Seaman was a virtual pet built around a microphone. Players returned each day to keep its habitat livable, feed the creature and watch it pass through bizarre stages of life.

The real novelty began when Seaman started asking questions. It remembered personal details, reacted to spoken answers and used its abrasive personality to disguise the limitations of speech recognition. Instead of treating voice as a set of simple commands, the game made conversation part of the relationship.

Designer Yoot Saito later said it helped Sega move past the idea that voice-recognition games simply did not work. Seaman was not the first videogame to recognize speech, but its success made it a visible demonstration of what voice interaction could do.
