For me the advantage for Echo is not so much in speech recognition, but in hearing all sorts of other cheap household sensors. An Amazon dash button that outputs a high-pitch sound can be manufactured ~10-30 times cheaper than one that needs Bluetooth and WiFi. A cheap Smokealarm can become fully networked, a doorbell heard can activate added features, etc.....
- pbreit 11y agoDoes Echo support this type of "networking" today?
- nitrogen 11y agoSome apps use this type of thing to link viewing profiles across TV, web, and mobile. There was a recent arstechnica article on the subject.
- fnordfnordfnord 11y agoSuper cheap short range transmitters already exist which don't require an audio frequency listening device (garage door openers, wireless doorbells, X10 type wireless controllers). The only thing missing to provide the same functionality for those devices as Echo could be built with a cheap SDR. The smoke alarm and doorbells are exceptions (and I guess there are several other good exceptions: clothes washer, clothes dryer, dishwasher, coffee pot) but I think I'd prefer a purpose-built listener with a high pass or notch filter. The Echo may have some unintentional funny failure modes, such as when a doorbell or other trigger sound plays on a TV commercial.
