Title:
INPUT METHOD OF INTELLIGENT DEVICE BASED ON FACE VIBRATION
Document Type and Number:
WIPO Patent Application WO/2020/206579
Kind Code:
A1
Abstract:
An input method of an intelligent device based on face vibration. The method comprises: acquiring a face vibration signal generated when a user performs voice input; extracting a Mel frequency cepstrum coefficient from the face vibration signal; and by taking the Mel frequency cepstrum coefficient as an observation sequence, obtaining text input corresponding to the face vibration signal by utilizing a trained hidden Markov model. The input method solves the problem of difficulty in typewriting on an intelligent device due to a too small screen or occupation of two hands of a user, and avoids the influence of replay attack and imitation attack.
