Alexa waits for user’s answer for only about 6-8 secs. In that case, IMO, users must speak very fast. Then, the more large numbers, the more likely Alexa may mistake.
Hey, thank you so much for this info. I think you are correct, because anything more than 19 gets converted into negative number. So the only solution would be to break down the number. Can you tell me if there is any datatype which accepts whatever user says, like a feedback. I have made a function which takes the text and convert it into digits. So, if there is such datatype which will accept whatever user says without converting into any format would be really helpful.
