Audio

Changes

To provide support for different languages, we edited the AudioPlayer and the Audio instructions in general. The AudioPlayer handles all incoming audio messages. These messages are just strings that get made in to speech using the TextToSpeech engine of Google/Android. If the standard settings are used the pronunciation may be bad if used for different languages, so we added a setting that reads the current phone settings and makes the speech engine work with the found default language. We also gave the audio strings used throughout the project an overhaul and made them support our localization using the strings.xml files for each language.

Future considerations

The audio will need to be tested in more detail during real life situations and changed according to the feedback of testers. The current audio warnings happen 30 meters beforehand and you can edit this here.
