An Android app that offers speech-to-text services and user interfaces to other apps

Kõnele

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

• a voice search panel (i.e. a RecognizerIntent activity)
• two implementations of SpeechRecognizer, backed by two open source speech recognition servers
  • https://github.com/alumae/kaldi-gstreamer-server
  • https://github.com/alumae/ruby-pocketsphinx-server
• a speech keyboard that implements the input method editor (IME) API

The diagram below shows Kõnele's main components in yellow, while the standard Android interfaces via which other apps can interact with Kõnele are in green.

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

Building the APK from source

Clone the source code including the net-speech-api and speechutils submodules:

git clone --recursive [e-mail]:Kaljurand/K6nele.git

Point to the Android SDK directory by setting the environment variable ANDROID_HOME, e.g.

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

Create the file gradle.properties containing the lines:

android.enableD8=true
android.enableR8=false

Build the Kõnele app

./gradlew assemble

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

• add these lines to gradle.properties:

  storePassword=<password1>
  keyPassword=<password2>
  

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