IBM Watson Speech to Text Only Returning First Word With Java SDK

I'm using the IBM Watson speech to text Java SDK, and when I upload the .wav file the response JSON only contains the first transcribed word. When I upload the same file to the web demo, I get the full response.

Very simple implementation with the SDK:

SpeechToText service = new SpeechToText();
service.setUsernameAndPassword("<username>", "<password>");

File audio = new File("src/test/resources/sample1.wav");

SpeechResults transcript = service.recognize(audio, HttpMediaType.AUDIO_WAV);
System.out.println(transcript);
