Google Cloud Text-To-Speech Powered by DeepMind WaveNet Technology
The average English word is 4.5 characters and the average English speaker speaks 110-150 words per minute. This means that at $16/1m characters, we can generate speech at a cost between $28.57-39/hr. Per Google's post, WaveNet now costs 50ms of TPU time per 1s of speech generated, meaning, at 100% utilization, a TPU can generate somewhere between $571.40-780/hr. Google's TPUs can be deployed (by third parties) at $6.50/hr. That's some sweet sweet margin.
