For fun at the party or just to be heard (for example, in case of a speech impediment): the mobile phone says (in Spanish) what you enter.
The app uses Android's text-to-speech feature to speak any word or sentence you choose to enter.
The five most recently used expressions are stored in a list, and up to five expressions can be assigned to the quick access buttons.
With Android 5.0 and higher, the voice to be used can be selected from the voices available on the device.
