I just noticed something in this video. Do you do a high-speed recording of the audio, or just slow down normally-recorded audio?
Come to think of it, I've never heard of a high-speed microphone, or the like.
High speed microphone would be essentially sampling at a higher rate I guess. I don't think it's as hard to do well as it is with video.
Also, creepy doll... O_O
Microphones output a constant analog signal, which is converted into samples when it's recorded digitally. Current sample rates top out around 192khz, which is 4x what digital camera systems generally input (48khz). The high sample rate recording systems are generally expensive, or at least time consuming to set up since it has to be synced with the video in post.
That said, high sample rates are helpful, but high quality software is much more useful when it comes to making sound seem slower than real time. A simulated audio stretch is usually more convincing than an actual one. More often than not, slowed-down audio is supplemented with additional noises and effects that aren't a part of the original recording when you see it in Hollywood movies as well.
