VoiceXML is designed for creating audio dialogs that feature synthesized speech, digitized audio, recognition of spoken and DTMF key input, recording of spoken input, telephony, and mixed initiative conversations. Its major goal is to bring the advantages of Web-based development and content delivery to interactive voice response applications.

Explanation of circuit and hardware components: As can be seen D1-D4 are connected to pinpin9 respectively, here D1 represents least significant bit and D4 represents most significant bit. Tones were generated via mobile phone and were fed as input to DTMF decoder module using 3.

For motor driver I used LD module.

With this information you can easily use my source code directly by changing your connection respectively. I set both of them HIGH in order to attain maximum speed.

Phone was mounted on servo motor. Explanation and working of peripheral applications used: First of all I connected my laptop and my mobile phone to the same network. This application was running on my mobile phone. Now in order to share the display and gain control over my mobile phone from my laptop I created a VNC server by running VNC server application on my phone in background and using VNC client on my laptop.

Now I was able to view my mobile phone's screen and simulated touches from my laptop. To get the live feed from my phone's camera I used AirDroid application, which was running in background alongside VNC server and using a browser preferably Chrome on my laptop I was able to use the camera of my phone.

Source code is well documented therefore all the required explanation is given as comments.

Instead of being on the same network one can control it via internet from any part of the world using VPN. One can use any tablet or phone which supports multi window instead of laptop, as the only required application on my laptop were VNC client and a web browser.

If only maximum speed is required LD can be used instead of L, which might in turn save some bucks. An extension of this project I tethered wifi from the phone mounted on the vehicle, thereby creating a local network. Now I was able to control my vehicle without the need of an external router or internet.Get the list of latest electronics mini projects ideas, which are very useful for engineering students to do their electrical and electronics projects.

This document specifies VoiceXML, the Voice Extensible Markup Language. VoiceXML is designed for creating audio dialogs that feature synthesized speech, digitized audio, recognition of spoken and DTMF key input, recording of spoken input, telephony, and mixed initiative conversations.

Its major goal. Internet of Things or IoT is an environment or network where everything and everyone are connected. Internet of Things is growing rapidly with more devices getting connected every day.
