A method for recognizing speech within a received audio signal includes separating, using a computer-based neural network model, a speech from an audio signal based on a speaker's audio profile, determining a command from the speech, determining, from the audio signal, a first score reflecting a percentage of confidence in determining the command based on a frequency of using the command by the speaker, determining, from the audio signal, a second score reflecting a percentage of importance of the command, and causing the command to be executed if the first score is above a first threshold value and the second score is below a second threshold value.
