Yes, I have seen the same info but am not sure about the Watson TTS node. With TTS presumably standing for Text To Speech, it doesn't seem to fit. There are other nodes available that play audio files and I have the same issue as you in regard to not being able to add nodes (and am watching with great interest for a resolution or work-around)
The play audio node works great for text to speech.
