alexa, play music. so what happens if you say a name that sounds similar to alexa? at the start we often the problem that, or example on the radio, a traffic jam on the road a96 was reported, then alexa woke up because this activation word detection was simply too sensitive. how do you solve that? we use alexa's pronunciation variants that users have said, as well as the misrecognized words,

to further improve our recognition system. so the more people use alexa, the better the recognition will become. alexa, turn off the screen. how does that work? i taught alexa that this power socket she can remote-control is called “screen”. i then plugged the screen into it, and now i can turn it on and off using this voice command. so i could say, “living room lamp on".

exactly. and if you’ve set it up with a device with that name, then it will work. and the interesting thing for us here is of course that german “living-room lamp”, where we combine two words into one, doesn’t work in english. but we still have to be able to deal with the slightly different meanings that result. first “living room” as the location and then “lamp” as the type of device that you want to switch on or off. alexa, how old is mario gã¶tze? mario gã¶tze is 24 years, 6 months, and 4 days old. how did you get her to be able to say that down to the day?

well, it might seem like a rather simple question but first you of course have to know who mario gã¶tze is. alexa learns that on wikipedia or from other information sources. and on the wikipedia page, for example, it shows his date of birth, which we of course need. and then we need to know what today’s date is. then we have to be able to calculate how old he is. and then we have to be able to say it, that is, to formulate it. all the little steps are processed one after the other and then she can give the answer that accurately.

by the way, everyone can help alexa get better and better with “skills” that you can program and write yourselves. so what exactly is that? a skill is like an app on your smartphone. everyone can add new capabilities to the device. it’s been operational in the usa for half a year already. we got it up and running for german last summer. and finally i treated myself to a little fun by writing an for my children on my own. alexa, start “brush teeth”. “let’s brush our teeth. do you have your toothbrush?”

yes. so that’s how your kids brush their teeth at home? yes, and with more motivation. so how about homonyms, when one word has two meanings? yes, alexa can handle that of course. she learns based on context, for example in the sentence “play the new piece by metallica”, that “piece” means a song or an album. while if someone asks about a piece of pizza and how many calories a piece of pizza has, the word “piece” carries a very different meaning.

or “make it a bit louder”, to set a volume level. and how does she know which “piece” is meant? alexa doesn’t learn individual words and combine the individual words to determine the meaning; rather, she learns context from complete sentences. and that makes it possible to know that, in a music request for example with a band name combined with “piece”, it very likely means a song. while the request about volume and “piece” very likely refers to the volume level.

what challenges are you still facing? for example, stuff like in english you can clearly distinguish the time of day using “am” and “pm”. in german, i can do that with “morgens” in the morning or “abends” in the evening. and if i say, for example, “i’d like to set an alarm for the morning”, that can mean either for one morning or recurring for every morning. alexa, what sound does a cat make? i’m sorry. i have yet to learn animal languages. so far i only know this: “woof woof woof”. “meow”. “oink oink”.
