Kõnele

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

ANDROID_HOME=${HOME}/myapps/android-sdk/

Build the net-speech-api jar-file (requires Maven)

gradle -b other.gradle makeNetSpeechApi
# alternatively: cd net-speech-api; mvn package -DskipTests; cd ..

Build the Kõnele app

gradle assembleRelease

If you have access to a release keystore then

• point to its location by setting the environment variable KEYSTORE

• set KEY_ALIAS to the key alias

• create the file gradle.properties containing the lines:

  storePassword=<password1>
  keyPassword=<password2>
  

The (signed and unsigned) APKs will be generated into app/build/outputs/apk/.
