more aware of its owner's location and
preferences.

August 17, 2005 and Rubin started working
with Google.
• At Google, the team led by Rubin developed a
mobile device platform powered by the Linux
kernel. And hence the android was developed.

Pre-processing on Acquire sample
HHM-Training
Text Storage

SPEECH RECOGNITION : Speech recognition is
very important part of this system in this phase speech
samples are obtained from Microphone at real time and
stored for pre-processing.
SPEECH PREPROCESSING : The voice which is
taken at the real time will Consist of noise Along with
speech signals so the background noise is removed. Which
reduces the amount of efforts in the next stages.
