Here is some code from here that helps you be backward compatible so you don't have to target 15.

private void setTtsListener()
    {
        final SpeechRecognizingAndSpeakingActivity callWithResult = this;
        if (Build.VERSION.SDK_INT >= 15)
        {
            int listenerResult = tts.setOnUtteranceProgressListener(new UtteranceProgressListener()
            {
                @Override
                public void onDone(String utteranceId)
                {
                    callWithResult.onDone(utteranceId);
                }

                @Override
                public void onError(String utteranceId)
                {
                    callWithResult.onError(utteranceId);
                }

                @Override
                public void onStart(String utteranceId)
                {
                    callWithResult.onStart(utteranceId);
                }
            });
            if (listenerResult != TextToSpeech.SUCCESS)
            {
                Log.e(TAG, "failed to add utterance progress listener");
            }
        }
        else
        {
            int listenerResult = tts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener()
            {
                @Override
                public void onUtteranceCompleted(String utteranceId)
                {
                    callWithResult.onDone(utteranceId);
                }
            });
            if (listenerResult != TextToSpeech.SUCCESS)
            {
                Log.e(TAG, "failed to add utterance completed listener");
            }
        }
    }
