RHVoice - a free and open source speech synthesize
APK
RHVoice is a free and open source speech synthesizer. Voices are built from recordings of natural speech. They have small footprints, because only statistical models are stored on users' computers. And though the voices lack the naturalness of the synthesizers which generate speech by combining segments of the recordings themselves, they are still very intelligible and resemble the speakers who recorded the source material. Supported languages: Initially, RHVoice could speak only Russian. Now it also supports American English, Brazilian Portuguese, Esperanto, Georgian, Ukrainian, Kyrgyz and Tatar. In theory, it is possible to implement support for other languages, if all the necessary resources can be found or created.

RacketGhost
APK
Ghosting is an established training exercise in racket sports to practice court movement without a ball. Moving to the various corners of the court improves both footwork and general stamina. In the best of worlds, your coach or sparring partner will always be ready to point you to random corners at a pace that pushes you to your limits. Unfortunately, few people have access to a coach at all times, thus have to run the exercise on their own. That means the randomness in the order of corners is missing. Getting Started 1. Configure your ghosting session. 2. Put your mobile device in front of you on the court. 3. Press "GO!" to start your ghosting session.
