Protect your audio with Voice123’s Voice Authenticity Initiative

The Voice Authenticity Initiative is Voice123’s first phase in creating an audio content security system so that voice actors can always own, access, and be able to verify their datasets and audio files. 

As the digital and AI content era evolves, we aim to set a new standard in audio security as we join The Content Authenticity Initiative to help all creators amplify and guarantee authenticity by securing all forms of their digital content. 

Starting with the Beta Voice Credentials – an audio security tool that automatically generates a unique digital signature for every piece of audio uploaded on Voice123.

Over the coming weeks, this tool will be incrementally released to all voice actors’ profiles so keep an eye on your Voice123 proposal inbox.

How does this affect you?

Every audio file you upload to Voice123 will be protected with your unique digital signature, which can be used to validate the provenance and ownership of each audio file and assist in identifying and tracking your work elsewhere, protecting against potential abuse.

How does it work?

We’ve been leveraging software advantages to generate a unique identifier for audio files that serves as a digital signature. This enables us to verify the original creator’s provenance and establish if the audio file was ever downloaded from Voice123. We refer to the metadata associated with a piece of audio content as Voice Credentials

The process of signing the files digitally will happen automatically with every new piece of audio, which immediately creates a record of that audio file and links it to the provenance metadata on our secure servers.

On the verification tool (launching later in 2024), a user can upload audio, which will then reveal the provenance data and verify that the signature is valid, present, and hasn’t been tampered with.

The Voice Credentials pin

Soon, when Voice Credentials is rolled out to all Voice123 profiles, you will be able to see the Voice Credentials pin. This means that Voice Credentials (metadata representing a digital signature) are attached! Simply click the pin to reveal more information about the content you’re listening to.


How it works

  • Anytime a voice actor uploads a casting proposal, a booking recording, or a profile sample, Voice Credentials will be attached
  • Voice Credentials are viewable across the internet
  • Once the content is made available, anyone can view its Voice Credentials by clicking the pin, which reveals the most relevant information directly in context.
  • Go deeper to explore the entire edit history

Voice Credentials can capture a detailed history of changes over time. The verify feature allows you to explore this information in depth and upload any content to see if it has Voice Credentials.

How does Voice Credentials facilitate audio security?

When a client downloads a signed file, the signature remains within the audio file. However, the signature can be removed or become invalid when someone attempts to edit or re-record that file.

If a voice actor comes across an audio file they suspect might be theirs, they can use the soon-to-be-released verification tool to check the provenance of that suspicious audio file.

If that file is signed, the signature will enable a voice actor to match it to the original.

If it’s not signed or the signature is invalid, they will be able (in the next phase) to trace it back to the original, signed file.

What do you have to do?

Absolutely nothing!

Just continue auditioning and uploading your audio files, as always. All audio files will be automatically signed with your unique identifier by our Beta Voice Credentials tool

What if you want to verify if a file has been used without permission? 

You will soon be able to access our free verification tool to see all the provenance information associated with the file – coming soon!

Future releases

As with all new tools, the possibilities and additions are endless. Here are our priorities for the future: 

  1. Launch Voice Credentials for all voice actors on Voice123.
  2. An inspection tool with the ability to find similar files – think of the way Shazam works, but instead of music files, you can track voice over files.  
  3. VoiceID: A digital fingerprint of a voice actor’s voice, which can be used to answer the question “Is this my voice?” on a given audio file. This can help detect if a voice actor’s voice was used without authorization.
  4. All voice actors can manage their signed files and change the metadata stored on a signed file.
  5. Public tools and APIs to sign and verify audio files with the possibility of allowing other apps and platforms to support the Content Authenticity Initiative.


We’re committed to launching The Voice Authenticity Initiative as quickly, transparently, and securely as possible.

But we understand there might be questions or even feature requests. Take a look at our detailed list of FAQS about Voice Credentials here.

Because we believe that every voice actor deserves to have their audio work protected.
