this is what i heard when i listened.
i am hearing a sample that has been auto-tuned and then ran through a vocoder and the carrier for vocals is most likely a saw or square since those are usually best for vocoding. then they probably took that .wav file and mastered it, then sliced up the wave. then im betting loaded it into a sampler and used pitch bends on it automated or by controller.
thats what i would have done. the synth they used sounds mid heavy. so ....use your best judgment but try to me basic. no crazy ass carriers unless they are saw based.
im not to sure if it was autotuned or not if it was it would have had to have been after production and vocoding because the autotune wouldnt really show up if it was a mono tone after going through the vocoder.
