Strengths and trade-offs
Our analysisStrengths
Tells where a speaker is, so the robot can turn towards them.
Picks a voice out of a noisy room better than one microphone.
Cheap and tiny.
Trade-offs
Struggles when several people talk at once.
The robot's own motors and fans add noise.
Hearing words is only the first step. Understanding them is the AI's job.
Why robot makers choose it
Our readA robot you talk to has to hear you across a room and know where you are standing. Four microphones is the usual low-cost way to do both.
This is our reasoning from the public facts. No maker has confirmed it.
