Google's AI Brainiacs Achieve Speech-Generation Breakthrough

WaveNet won't have immediate commercial applications because the system requires too much computational power: it has to sample the audio signal it is being trained on 16,000 times per second or more, DeepMind said. And then for each of those samples it has to form a prediction about what the soundwave should look like based on each of the prior samples. Even the DeepMind researchers acknowledged in their blog post that this "is a clearly challenging task."
