I've been talking to it in spanish to practice. Literally, just say something in spanish and it will respond in spanish. Regarding quality, I'm pretty sure it's about the same as english; technically correct just aggressively formal. I asked it to play a game where it gave me a sentence in english, I translated it to spanish, and it graded my translation. I had to explain it about 5 times because it kept giving the spanish translation itself first. But eventually it got it. Nice tool for language learning, imho.
