BRING Voice control TO SMART office

DESCRIPTION

AI project integrated on the microprocessor (microcontroller) to control the device in the office by voice locally (without the presence of wifi, computer, ...)

SYSTEM PRINCIPLE


TRAINING MODEL

  1. Collected data will be pre-processed for labeling, diversity , cleaning (noise removal, mute sounds) , ... and then characterized by MFCCs for training. n model two models.

  2. The dataset consists of 8 keywords, each keyword that includes more than 130 speakers are collected

KEYWORD DETECTION

  1. Sound data will be continuously collected by the sensor in real time.

  2. Segment each audio segment in fixed time, perform feature extraction directly on MCU and put into the model to make predictions. If the wake-up keyword pattern is detected at first, then it will move on to active keyword discovery with model number two.

  3. If action keyword is detected then start taking the specified action.
