I built a skill that's recently been certified called "Teacher for Alexa". The premise is to take two random numbers between 0 and 10, then ask what the answer is to a math question with those two numbers (e.g. 2+5, 6-1, 3x4, etc). In using the skill I've experienced times when it will seemingly randomly direct to my "QuitIntent" which handles responses like "quit", "I'm done", etc. After testing multiple times I've narrowed it down to quitting when the response is "eight". What's interesting is if I accentuate the "t" sound in the word "eight", Alexa hears it properly. If I say it a bit more naturally and don't accentuate the "t", it quits. I tried to see if one of the utterances for the QuitIntent are too similar by simply removing them. When I did that, "eight" would just route to some other intent. No matter what I've tried, I can't get "eight" to route to the right intent without the accentuated "t". Anyone have a similar experience or any ideas? If interested, you could try this for yourself by enabling the "Teacher for Alexa" intent. Thanks in advance! Ian
My skill had trouble with the word "through", Alexa often interpreted it as "three". Especially with phrases such as "five through nine". Alexa would hear "five three nine". I had the most success fixing this by providing feedback in the Alexa app and creating an alternative way for the user to phrase the information. It's still not perfect but I documented what worked specifically for my skill here:
I wrote a UPS package tracking skill that had to import a similar number of alpha-numerics. The solution I used was to input them, three at a time, and read them back to the user as we went. If you want to use/learn from the code, it is here:
I've also noticed that Alexa has a hard time with the word "Eight". I built a skill to record reward codes for MyCokeRewards, which involved reading a string of 14 alphanumerics, and "Eight" was a pain point. Unfortunately, I don't have a solution for you - it's still flakey - although using a custom slot type did help lessen the frequency for me.
What slot type is "eight"? (And for that matter, "quit"?)
You could try try putting one or the other (or both) in custom slots types/literal slot types and see if that helps. (That is, have a custom slot type for the numbers 0 - 10, and a custom slot for quit | exit | cancel.
Perhaps some combination of custom/literal/number slot types will help?
