Tonaccenter
An Android app for the study of Swedish tonal word accents.
It uses the audio files and metadata distributed as part of the Language Melody Game (Språkmelodispelet) which was developed at a research project at Lund University, but this app is not associated with that research project and does not share any code with the official game.
The app has a bare-bones version of the core gameplay, with neither levels, scoring, nor jumping dinosaurs. It allows filtering of the available sentences by accent types and focus levels, as well as by word categories. Additionally, it displays a plot showing the pitch and the intensity of the recording (obtained from Praat) around the cut off point.
Installation
The app itself can be built and installed with Android Studio as normal, but the code is quick-and-dirty, and as such it needs the audio files, pitch and intensity data, and the metadata database to be generated and pushed to the device manually using the following process:
-
Install Praat and Parselmouth.
-
Download the Windows version of Språkmelodispelet and unzip the file.
-
Convert the OGG files under
res/audioin the extracted zip file to WAV so that Praat can analyse them, and then extract the pitch and intensity information using Parselmouth:$ parallel -v oggdec {} -o {}.wav ::: *.ogg $ parallel -v tools/wav2pitch.py {} ::: *.wav -
Convert the sentence metadata and the pitch and intensity information to the app's database format:
$ tools/sentences.py Melodispelet_Win32/ -
Push the OGG files and the database to your device via ADB:
$ adb shell device$ mkdir -p /sdcard/Android/obb/se.whitchurch.tonaccenter/ $ adb push sentences.db /sdcard/Android/obb/se.whitchurch.tonaccenter/ $ adb push audio/*.ogg /sdcard/Android/obb/se.whitchurch.tonaccenter/
