Hello Nomad, which speech recognition skill are you using? Do you have screenshots of what you are describing?
hi jeremy
thisone . its the disable frase .
thank you
You have two spaces (You hit the space bar twice). You must separate words with one space only to be grammatically correct. Remember, the phrase you enter is matched against what is detected. You can't speak with multiple spaces between words. There is only ever one space between words.
