Kõnele is an Android app that offers speech-to-text services to other apps. Its main components are:

• RecognizerIntent activity
• speech keyboard that implements the input method editor (IME) API
• SpeechRecognizer implementation that uses https://github.com/alumae/kaldi-gstreamer-server
• SpeechRecognizer implementation that uses https://github.com/alumae/ruby-pocketsphinx-server

The main goals of this project is to offer support for Estonian speech recognition on the Android platform, as well as grammar-based speech recognition for voice command applications.

How to add support for other languages than Estonian is detailed in Kaljurand#38
