We can stop ALS from stealing more voices

ALS is also known as Motor Neurone Disease, a progressive neurodegenerative disease that, amongst other symptoms, often takes away a person’s ability to speak. Project Revoice is a non-profit initiative with the ultimate goal to ensure that no one living with ALS will ever have to suffer being robbed of their voice.


“ALS has lost this round”

As co-founder of the ALS Ice Bucket Challenge, Pat Quinn helped give the global ALS community a voice, until the disease robbed him of his own. This is the story of how he got it back.


Your Voice. Recreated.

With breakthroughs in voice technology, it’s now possible to synthesize and fully recreate the unique essence of any voice and build a complete digital voice clone.

With just a couple of hours of high-quality recordings to work with, this technology can make your digital voice clone sound natural, dynamic and – most importantly – just like you. Project Revoice aims to give more people with ALS the opportunity to record and recreate their own unique voice for future use with Augmented/Alternative Communication (AAC) devices.


Create your Revoice today

Together with Lyrebird we’re now ready to present the next stage of Project Revoice! As of now, you can create a digital clone of your own voice with our Project Revoice partner, Lyrebird, free of charge. All you have to do is:

  1. Create your own Lyrebird account on
  2. Record yourself using a high-quality microphone for a minimum of 30 sentences. PLEASE NOTE that your voice quality will improve the more you record. We recommend recording a minimum of 300 sentences, which will take 2-3 hours. 
  3. Once you’re done, the voice will take a little while to generate. You can then test your recreated voice straight away. 

For now, the Lyrebird website is great for testing your recreated voice, and we’re currently exploring a custom Project Revoice solution to improve your day-to-day use. 

It’s important to note that not everyone’s voice is suitable for this technology. If you’re unhappy with the end result of your Revoice, click here to find a guide to alternative options available. We encourage you to discuss these with an assistive technology expert or email If you live outside the United States you can find a local ALS/MND association here.

What is ALS/MND?

Amyotrophic Lateral Sclerosis (ALS) is also known as Motor Neurone Disease. It’s a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord.

When these motor neurons die, the brain’s ability to initiate and control muscle movement is lost. With voluntary muscle action progressively affected, patients in the later stages of the disease may lose the ability to move, speak and finally to breathe.


Frequently asked questions

What is Project Revoice?

Project Revoice is an initiative from The ALS Association (USA), working in partnership with an Australian creative agency, a Canadian technology company, and Australian production houses. Together, we’re working to give ALS/MND communities the opportunity to record and digitally recreate their voices. This cutting-edge voice technology – in combination with Augmentative/Alternative Communication (AAC) devices – will give ALS patients the ability to communicate with their own voice, even after they can no longer speak.

How does it work?

Project Revoice is powered by breakthrough voice cloning technology, developed by our Canadian software partner Lyrebird. With 2-3 hours of high-quality audio recordings to work with, this model can synthesize the essence of your voice and build a complete digital recreation of it.

How is it different from existing tech?

Until now, the two main sources of preserving voices have been either message banking or traditional voice banking. Message banks enable users to record everyday lines of speech, which are then played back at the touch of a button. Traditional voice banking requires users to record thousands of sentences, which can take weeks or months to complete. This speech is then cut and pasted together to re-create sentences.

Project Revoice allows users to deliver new lines of speech using their recorded voice in an entirely new way. Using only 2-3 hours of recorded speech, the advanced technology uses machine learning to clone voices and recreate natural expressive speech to a level that has never been achieved before.

Can I test what my Revoice might sound like now?

Yes, you can go to our partner Lyrebird’s website and create your Revoice today.

Are you working with other ALS/MND organizations around the world?

Yes. We believe that no one living with ALS/MND should be robbed of their voice, no matter where they live or from whom they get their support. We are currently working with our global project partners to make the process of digitizing voices easier and quicker for all, wherever they live.

How will I be able to use my Revoice?

Once you have recorded and created your voice, you can test your Revoice straight away on Lyrebird’s website. We are currently exploring a custom platform for Project Revoice that is more tailored to the needs of people with ALS/MND. Future updates may include other ways of accessing your Revoice.

How else can I record my voice today?

The ALS Association is proud to have provided financial support to the Augmentative Communication Program (ACP) at Boston Children’s Hospital, led by John Costello. This program promotes the development and adoption of comprehensive and proactive technologies, including “message banking,” allowing people with ALS to communicate in their own voice. You can learn more about the ACP here.

In addition, Team Gleason recently announced that they have partnered with ModelTalker to fund voice banking for people with ALS. You can learn more about that program here

We believe Project Revoice is an addition to this landscape and we support all efforts to make assistive technology and voice banking as accessible as possible to people living with ALS/MND.

Why are you sharing this website prior to the full application being ready?

First, given the progressive nature of the disease, we wanted to ensure that people with ALS who still have their voice have the option to create their voices now via the website. Second, we wanted to help raise awareness of ALS and the effects of the disease on a person’s ability to speak. Finally, we wanted to help people with ALS understand the benefits of recording their voice – via this site, ModelTalker, or any other technology – while they still can.

I have recordings of my voice already saved. Can my voice be recreated via Project Revoice?

Unfortunately, for the time being, a Revoice can only be created using the voice banking feature on this site. Pat’s Revoice was the product of many months of pro-bono work by several different agencies who were inspired by his work to raise awareness of ALS. We are exploring other options to try to help people who may have recordings of their voice but can no longer speak or use the voice banking feature on this site.

Who should I contact if I have more questions?

This is an evolving project and we will continue to provide more information via email and we will update the FAQ on this site. If you have additional questions, please send an email to If necessary, you can call 1.800.782.4747 and refer to Project Revoice.
