Smeech is an easy-to-use and lightweight application for using text-to-speech in languages like: English, German, Spanish, French and many more! The app itself was another experiment at the time I was starting with App Inventor.
You can write some text, then adjust the speed-rate and the pitch of the voice. Finally, you just need to click Speak and you will hear the text you typed (if the sound volume is high enough of course).
OS: Android Only
Requirements: An active internet connection / offline text-to-speech packages.
