Ask HN: Is there an equivalent of “whisper” but for text-to-speech?

Some of you have probably seen the recently released whisper model from openai. Having this go two ways would open up for some neat conversational ai ideas, as in having two AIs discussing with each other, say backed by GPT3 but the output form being perfect audio/speech

So is there something as "state of the art" as whisper but for text to speech/audio?
