Voice Recognition Using web camera and Google API - Raspberry pi 3B (python)
Voice Recognition Using web camera and Google API - Raspberry pi 3B (python). I am trying to find a Speech recognition library similar to PySpeech that will work on a Raspberry Pi 3. Google API is best for speech recognition because google api use hidden markov model for recognition. there are steps given below for voice recognition Required module: 1. Raspberry pi model 3 B 2. Logitech Web camera 3. Rasbian os installed SD card Hidden markov Model: - Hidden markov model is used to convert speech into text and recognized it. - In HMM, speech signal is divided into 10-millisecond fragment. - Every fragment converted into power spectrum. - Then each power spectrum converted into frequency domain. - In last each frequency domain fragment converted into vector. this each vector compare with google speech API vector. - Dimension of these vector usually small, sometime 10. More accurate system may have ...
