Amazon Shopping – Just a Phone Call Away! February 9, 2009
How often you’ve had the need to check an item from an online vendor while shopping in a store? e.g. lets say you were in a bookshop and a novel looks interesting to you. Before purchasing it you want to go over reviews and maybe even want to do a comparative price search and possibly buy it online if it is priced better. In the ever connected world we live in, this isn’t anything new.
Being able to access information when I want it and where I want it is becoming more and more of a necessity than a luxury. Whatever ‘it’ is, the idea is to access all the information about that item at that particular moment.
In this application, we demonstrate how easy it is to use VoicePHP to build a complete voice accessible shopping experience. In particular, the application does the following:
- It allows users to type in an ISBN number. For e.g. (ISBN-10: 0375826726 or ISBN-13: 978-0375826726 for “Breaking Dawn”, ISBN-10: 1416562605 or ISBN-13: 978-1416562603 for “White Tiger”)
- Hear reviews, price and other information
- Provides skeleton code to implement the payment and shipping logic.
So next time you are in a bookstore, feel free to call 15672449576 to get more information on any book. This code can be easily extended to integrate other products offered by Amazonn or a completely different seller.
Disclaimer: Credit card number and shipping information is only being asked for demonstration purposes. We do not store any of that information and will not be sending that to Amazon (as you can see in the code). Please use your judgement when providing that information.
