Playing an audio file with alternate synthesis text

It is possible to play altenate content whenever an audio cannot be played (i.e. fetch problem, bad file format, etc). The alternate text can be specified as the second argument of the fromLocation factory method:

Dialogue.java:

//Play an audio file with alternate content
String recordingLocation = context.getContextPath() + "/audio/test.wav";
String alternateText = "This message is played because the audio file could not be fetched";
AudioFile audioFile = AudioFile.fromLocation(recordingLocation, alternateText);
Message message = new Message("recording-message", audioFile);
DialogueUtils.doTurn(message, context);

The alternate text can either be a String or a SpeechSynthesis. Either way, it will generate synthetized speech.
