Software for iphone

We need a application design for the iPhone that will convert voice into text to be sent via sms on the iphone.? When user presses a button on the iphone they can pick who the sms is going to or reply to a sms then begin talking and it will convert the voice file to text and then press send to send it to the receiver of the sms.? *This process is in the process of becoming patented with our company
