I have created a zip code slot that takes american zip code as an input. The problem I am facing is when alexa re-confirms the slot instead of reading it as digits (like for 62999 it should say six-two-nine-nine-nine) it says sixty two thousand and nine..... Although I need the slot input in numeric form but i want alexa to read it out as digits. I have tried changing the slot type to Number, FourDigitNumber, and PhoneNumber etc but no luck. I also went through SSML tags but I am not reconfirming through code (like emit(<say-as> 62999 )), its all being done through setting slot as required from skill website. Can anyone please help ?
