I actually really like it. I disagree with those saying it's too flat/emotionless. It's soft, and well, guarded, if you will. The ghost has just met someone they know is really special, but they don't really know them personally yet. I'd be a bit cautious as well. However, it could create some weirdness with the thirstier males... Anyone seen the movie "Her", with Joaquin Phoenix? To sum up, great work OP! I think a female voice option would be really cool. More choices is usually better.
