I need to implement a voice based shopping cart in my application. There are not much products in my website.I have only "talking credit" to sell. At the time of signup i capture all the payment info. So next time when he comes for top-up he will say only the number which corresponds to a particular amount(say 1-$10,2-$203-$30 etc ) .Here I want to use the voice recognition. When he says something, i need to check with the available options, whether this is a valid option or not and if it is a valid option, i need to process a credit card using any payment gateway. I have the payment processing code. so that is not a problem. But about the voice recognition part, i searched the internet but got only examples showing windows application code and most of them in VB.net.
this is not possible to implement in C# web application or what?
Also if i write the customer said option in a textbox, can i do the option checking and payment processing in the textbox text changed event?
