Hi,
Thank you for your reply,
I want to add my own command. like if I say anyone name, Alexa wants to tell full profile
for that, I want to include name and profile of that person in Alexa side
I don't know how to integrate name and profile of particular People in Alexa
You are asking for some very customized programming using Alexa's voice recognition engine. At this point, I can say that you won't be able to get that accomplished with the current Echo devices. At best, you might be able to do this with a customized skill. With the proper skill, you might be able to say something like: Alexa, ask PeopleFinder who is Bob Smith? (PeopleFinder would be the name of your customized skill). But if you want Alexa to answer directly to questions like: Alexa, who is Joe Smith, that just won't happen unless Joe Smith is a famous person with an entry in Wikipedia.
On the other hand, if your company is big enough to get Amazon's attention (big like Microsoft, Facebook, Boeing, Ford, etc.) you may be able to talk Amazon into making this specialized device with customized software that can do what you described.
