Hablame, or Tell Me! in English, is a nice application that reads for you any text you write or paste in the text field. You can use this app to have some fun or to protect your throat in cases of irritation or aphonia. It is also useful for people who have difficulty speaking.
It supports texts in multiple languages and allows you to adjust the tone and speed of reading. It also allows you to download the texts as an audio file in MP3 format.
