For years I thought it would be fun to embed a smart assistant like Siri or Alexa into a plush toy like Teddy Ruxpin so a child can converse endlessly with a character they enjoy. However I was not comfortable with all the electronics that would be inside the plush toy, or the upkeep that would be needed (like charging the battery or cleaning the plush toy).
I feel it would be best if all of the electronics were completely separated from the plush toy, and placed in a walkie-talkie that the child can interact with. The plush toy would be holding a walkie-talkie too, but it would have no electronics, it is just a prop. The battery, speaker, microphone — everything needed to engage with a smart assistant is in the main walkie-talkie.
As for the smart assistant, I’m not sure if Siri or Alexa can be given the helium treatment to sound like Elmo, or if the character’s voice actor would need to record new dialogue, but either way the voice is a very important feature for this toy, it is the main selling point after all.
Ideally a child can have entire conversations with Elmo, play games, or even be quizzed for an educational aspect. The sky’s the limit with smart assistants, although this one would need parental controls obviously.
