Maybe voice recognition isn't the right word, some examples of what frequently happens.
I ask Alexa to play the Trine soundtrack which is in Amazon's library, and I get things like For Crying Out Loud, or something else other than what I asked for. I try adding the artist so I'm asking for Trine soundtrack by Ari Pulkkinen and Alexa reports that it can't find it, yet there it is, in Amazon's digital library and it even says that you can stream it on the Echo. Nope! No matter what I do or how carefully I enunciate the words, Alexa simply refuses to find it or play the right thing.
Or I'll ask Alexa to play WSMR, a local radio station, from Tune In, and it plays WMOR instead.
And then there's the features that don't work properly. One of them is the ability to have Alexa notify you when an order is out for delivery or has been delivered. Numerous times I've had Alexa tell me an order will be delivered today when it is still days away, or tell me that an order has been delivered when no package has arrived. This make the notifications practically worthless, so I turned them off.
And that's just some of the many problems I've had with the Alexa service.
And the iOS Alexa companion app, needed to set up the Echo's, it has constant problems with buttons and controls that don't work when Voice Over is turned on, and it must be pretty bad without it too, because it has only a 1.5 out of 5 star rating in the app store, the last time I looked, plus I've heard the Android version isn't much better.
If hadi's remark that Amazon is hiring more developers than Google is right, it wouldn't surprise me one bit, if the quality of Alexa and the companion app are any indication, Amazon desperately needs those developers, let's just hope that these new developers are better than the ones they already have or it's just going to be more of the same crap from them. Google on the other hand has been a development company from day one, so they already have a ton of developers in their employ and don't need as many as Amazon apparently does.
Simba, you're from Europe, ever listen to a European voice compared to an American voice? You Europeans enunciate your words differently than we Americans do, and for voice recognition that can make a very big difference. I'm actually surprised that you didn't realize or consider that.
