To call Azure Marketplace Translation (and Speech) service

Dependencies:   EthernetInterface-FRDM HTTPClient-SSL R_BSP SDFileSystem TLV320_RBSP USBHost mbed-rtos mbed-src

The program calls Azure Marketplace Translation (and Speech) service.

How to use - Create an account for Microsoft Azure Marketplace - Get client ID and client secret. - Change client ID and client secret in main.cpp

The program was created based on the following libraries.

CodePlex Text-To-Speech with Microsoft Translator Service http://translatorservice.codeplex.com/
