I have developed a skill and everything is working smoothly except few words when asked to alexa. For example: If i am saying first, alexa is never getting first and log is saying that alexa heard frost, horst and many more word but first. Same goes for more, when I am saying more, alexa heard mor, mour,moire but more. These words are working good on mobile device but not on dot and spot. saying these word causing alexa to fire stopIntent. When i have fallbackIntent, then why it is firing StopIntent? Also i added mor in utterances but it doesn't pick up yet.
