Speaking Aid+ was designed on iOS 7+ for those who have speech impairments. It utilizes touch and keyboard input, and is designed with speed and simplicity in mind.
It is as simple as typing and clicking the return key.
Unlike Speaking Aid, this application does not support multiple voices but instead uses your devices locale to determine the appropriate voice and settings. It has better volume and a simple slider on the main screen to adjust the speech speed.
