THE NEXT GENERATION OPERATING SYSTEM

HISTORY OF ANDROID• Android Inc. was founded in Palo Alto

California on October 2003.One of the founders of Android Inc, Andy Rubin wanted to develop smarter mobile devices that are more aware of its owner's location and preferences.

• Later Google acquired Android Inc. on 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.

UNDERSTANDING ANDROID

• Android is a Linux-based operating system.• Designed especially for Smartphone and tablets,

developed by Google combining with other Open Handset Alliance (OHA).

• Initially Android was developed by Android Inc which was later purchased by Google in 2005 and brought up with a project called Android Open Source Project.

SMART TEXTING SYSTEM SPEECH TO TEXT : This project converts

speech into text. At the run time speech data is acquire from microphone and converted into text and are then passed for pre-processing and after pre-processing HMM-based training is applied on it. Speech Recognition

Pre-processing on Acquire sample HHM-Training

Text Storage

SMART TEXTING SYSTEM 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.

HMM TRAINING : HMM is a statistical model used for Modelling an unknown system. The system trains the HMM for each digit in the vocabulary using the Baum-Welch Algorithm.

CONCLUSION

From the Power Point Presentation We have learned about “Android Operating System”... And it’s “Versions” .The Services offered by the Android Operating System.Then We have learned about Smart Texting System i.e “Speech-To–Text” .Which converts speech to Text.
