Siri could be getting a new job soon at your bank.

The folks behind Siri, the iPhone's virtual personal assistant, are bringing the technology to customer service applications, including bank, cable and credit card smartphone apps.

Nuance Communications last week announced the creation of "Nina," a natural human language input software that is designed to understand customers' questions about their accounts. Think of Nina as Siri's cousin who lives inside your credit card app instead of your iPhone.

Nina could be molded to suit any customer-focused application, but in a demonstration with CNNMoney, Nuance chose a banking app to illustrate the technology's capabilities. Just as Siri understands that "Do I need an umbrella today?" is a question about weather, Nina can field contextual questions.

For instance, an order to "Pay my bill" brought up Nina's response -- in Siri's familiar voice: "How much would you like to pay?"

Nina understood the reply of "my statement balance," and asked whether she should go ahead with the payment right now.

"No, let's do it on Monday," got a response of "Okay, I'll set up your payment for this Monday."

The software can also check balances, transfer money, and troubleshoot problems, among other tasks. Nuance said the idea is to make Nina smart and fast enough to encourage users to go to the app first, before dialing a human customer service representative.

If a customer's issue needs to be handled by a human being, Nina comes with a neat trick: The software can call a rep and provide the company with all the details of what the customer has been trying to accomplish. That means no more sorting through an endless series of call center menus and then having to explain the problem again when you finally get a human being on the other end of the line.

Nina also comes with an analytics engine that informs companies about how customers are using their apps.
