Abstract
The disclosure is directed to a directional keyword verification method and an electronic device using the same method. According to an exemplary embodiment, the proposed keyword verification method would include receiving an audio stream; analyzing the audio stream to obtain at least a word; determining whether the word matches a key word from a keyword database; assigning the word as a filler if the word does not match the keyword from the keyword database; determining whether a vowel pattern of the word matches the vowel pattern of the keyword if the word matches the key word from the keyword database; assigning the first word as a trigger or command word if the vowel pattern of the word matches the vowel pattern of the key word; and otherwise assigning the word as a filler if the vowel pattern of the word does not match the vowel pattern of the key word.
