I wanted to ask if the car launch project can be started by lotus with a VOICE CONTROL app
Please elaborate.
E.g.
What is "car launch project"?
What is "lotus"? The car manufacturer? The spreadsheet program?
How do you see fit Arduino in your project?
Can you link to what "lotus" is in this context?
And what this "car launch" project is? There are hundreds or thousands of books of Arduino projects, and we don't know which one you are using, much less have a copy.
"lotus" and "car launch" are words/phrases too generic for us to google and have any confidence that our results are the same as what you're talking about (and since you're asking us to help you for free, you should be doing this legwork for us)
That all said, getting good voice recognition on an Arduino is hard - you need external hardware for it, and it's always going to be way worse than Alexa, Siri, or the other common voice recognition things that we use in our daily lives now. All of those are only able to recognize their wake word on their hardware - after that, they just detect when there's a pause in what your saying that indicates you've finished saying the command. Then they ship the audio clip up to the manufacturer's cloud servers, where they can devote a huge amount of processing power (for a fraction of a second) on a system that's been trained on a massive dataset. And quite frankly, even then, the result isn't that good.
When I tried to make this work with a voice recognition board, I was never able to get a usable recognition rate; with EasyVR I think I got like 5-10% success recognizing a command - utterly worthless. I was using it for home automation, and gave up trying to do the voice recognition myself, and just used a python script on a raspberry pi running "fauxmo" which pretends to be a Wemo Smart Outlet, and used Alexa to do the voice recognition; this works very well.

Not to be confused with the Australian Prime Minister. 
Please post a link to VOICE CONTROL app
If you are using a VOICE CONTROL library please post a link to that as well as there may be different ones.
Lastly read how to use this forum.
It is a ststicky Post on the top of each forum
Pay attention to #7 code tags
So you can post you sket h.
