A placeholder. Generating speech, without a speaker, or possibly style transferring speech.
You have a recording of me saying something self-incriminating. You would prefer it to be a recording Hillary Clinton saying something incriminating. This is achievable, although the open-source options are not impressive, the pay-to-play options are getting very good.
VoCo seems to be a classic concatenative synthesis method for doing “voice cloning” which generally will work on small datasets but won’t really generalize beyond the subset of sound tokens you already have, I did a blog post on a really simple version of this.
There’s another cool webdemo of how this works. Improving concatenative results to get VoCo level is mostly a matter of better features, and doing a lot of work on the DSP side to fix obvious structural errors, along with probably adding a language model to improve transitions and search.
You can see an example of concatenative audio for “music transfer” here.
I personally think [Apple’s hybrid approach]((https://machinelearning.apple.com/2017/08/06/siri-voices.html) has a lot more potential than plain VoCo for style transfer — I like this paper a lot!
For learning about the prerequisites to Lyrebird, I recommend Alex Graves monograph , then watching Alex Graves’ lecture which shows the extension to speech, and maybe checking out our paper char2wav. There’s a lot of background we couldn’t fit in 4 pages for the workshop, but reading Graves’ past work should cover most of that, along with WaveNet and SampleRNN. Lyrebird itself is proprietary, but going through these works should give you a lot of ideas about techniques to try.
I wouldn’t recommend GAN for audio, unless you are already quite familiar with GAN in general. It is very hard to get any generative model working on audio, let alone GAN.
By Corentin Jemin, Real-Time-Voice-Cloning will Clone a voice in 5 seconds to generate arbitrary speech in real-time. Need multi-gigabyte GPU but quality is OK.
No-frills poor-man style, RandomCNN voice transfer does voice style transfer via random feature matching.
Voice conversion (VC) is a technique to convert a speaker identity of a source speaker into that of a target speaker. This software enables the users to develop a traditional VC system based on a Gaussian mixture model (GMM) and a vocoder-free VC system based on a differential GMM (DIFFGMM) using a parallel dataset of the source and target speakers.
Text to speech
char2wav shows how to conditionalize an acoustic model
How siri does speech is kinda interesting.

Library to build speech synthesis systems designed for easy and fast prototyping.
Merlin is a toolkit for building Deep Neural Network models for statistical parametric speech synthesis. It must be used in combination with a front-end text processor (e.g., Festival) and a vocoder (e.g., STRAIGHT or WORLD).
PyTorch implementation of Generative adversarial Networks (GAN) based text-to-speech (TTS) and voice conversion (VC).
