The quality also depends on the type of model. I'm not really sure what ESpeak-ng actually uses? The classical TTS approaches often use some statistical model (e.g. HMM) + some vocoder. You can get to intelligible speech pretty easily but the quality is bad (w.r.t. how natural it sounds). There are better open source TTS models. E.g. check https://github.com/neonbjb/tortoise-tts or https://github.com/NVIDIA/tacotron2. Or here for more: https://www.reddit.com/r/MachineLearning/comments/12kjof5/d_...

I think your last point may hold for this genre of music but not necessarily for pop. Pop musicians are extremely versatile. They sort of have to be to stay relevant. Take Ariana Grande for example. She could sing basically anything in any style you want[0], but you may not even have to ask her because we have efficient zero-shot voice cloning now[1]. Before you wonder if this will work for music, check out this video of AI generated Eminem track[3].

There have been quite a few recent advances in open-source TTS, such as: https://github.com/NVIDIA/tacotron2 https://github.com/CorentinJ/Real-Time-Voice-Cloning https://github.com/mozilla/TTS I think a lot of the remaining gap is due to a lack of high-quality training data -- most of the open-source models are trained on public-domain audiobooks (e.g. LJ Speech). However, good training data (large amounts of annotated recordings by professional voice actors) is expensive to create, and unlike code, there's not a tradition of people sharing it.

> have produced the most realistic AI simulation of a voice we’ve heard to date. No you didn't. Please do not lie. There are a number of projects replicating Google's Tacotron 2 research from December 2017 that achieved human parity in text-to-speech as measured by MOS score. Google's Tacotron 2 model was then successfully deployed by Google in a service called Duplex. Following up on this research, there are a number of open source and commercial projects that have used Google's Tacotron 2 human-parity TTS research: Open source projects: - https://github.com/mozilla/TTS - https://github.com/Rayhane-mamah/Tacotron-2 - https://github.com/NVIDIA/tacotron2 Commercial TTS projects: - http://deepzen.io/ - https://wellsaidlabs.com/ - https://ai.googleblog.com/2018/05/duplex-ai-system-for-natur... ------------------------------------------------

It's absolutely unresponsible/illegal to clone a person's voice without consent. To use Joe Rogan's likeness for your publicity stunt without his consent is unethical in its self. It's Joe Rogan's legal right to control his own likeness. Furthermore, this presents a number of safety risks to Joe Rogan including the possibility of identity fraud. -------------------------------------------------- Finally, at this time, TTS human parity technology is at human-parity when tested on phrases and sentences similar to those in the training set. Google's Tacotron-2 models showed a significant decrease in performance reading 37 news headlines. They mentioned in their evaluation: > This result points to a challenge for end-to-end approaches – they require training on data that cover intended usage.

Worth noting that a big chunk of the core TTS code here is built on tools from other researchers like Ryuichi Yamamoto and Keith Ito, and they have great implementations to check out as well. The best quality I have heard in OSS is probably [1] from Ryuichi using the Tacotron 2 implementation of Rayhane Mamah, which is loosely what NVidia based some of their baseline code on recently as well [3][4]. There's also a colab notebook for this stuff, so you can try it directly without any pain https://colab.research.google.com/github/r9y9/Colaboratory/b... I also have my own pipeline for this (using some utilities from the above authors + a lot of my own hacks), for a forthcoming paper release here https://github.com/kastnerkyle/representation_mixing/tree/ma... , see the minimal demo.

s high as WaveNet. I'd really like to tie in with WaveGlow, but it's work in progress for me so far. NOTE: None of these have voice adaptivity per se, but given a model which trains well already + a multispeaker dataset with IDs such as VCTK, a lot of things become possible as getting a baseline model and data pipeline for TTS is quite difficult.
