In this post I’m going to show you how to make a deepfake voice in less than three minutes, that sounds as realistic as this:

Here are the exact steps to do it:

How to Deepfake a Voice

Select or Upload a Voice to Synthesys
Add Your Script
Customize Speed and Pauses
Save Your Project
Download the Deepfake Voice

1. Select or Upload a Voice to Synthesys

Go to Synthesys and either upload a new voice or select an existing one.

2. Add Your Script

In the text box, type out the words you want the voice to speak. For the best, most realistic results, write it just like you would say it out loud, with all the natural pauses and emphasis.

Note: If you want to create a conversation using different voices, you can select additional voice actors from the list. Add new paragraphs for each speaker within your script.

3. Customize Speed and Pauses

Use the sliders to tweak how fast the voice talks and how long it stops for breaths. Press the play button to listen to a sample. It helps you hear if it sounds natural or if you need to tweak it a bit more

4. Save Your Project

Happy with the way it sounds? Click 'Save project' to keep it. You can come back to it if you need to make changes later.

5. Download the Deepfake Voice

Once everything is set, download the voiceover in an audio file, to your device.

That’s it!

Are deepfake voices illegal?

The legality of using deepfake voices hinges on the intent and application. It's illegal when used for malicious purposes like fraud, impersonation, or spreading harmful stereotypes that could damage public trust or individual reputations. However, deepfake voice generators and voice conversion tools are legal for creative, educational, or entertainment purposes, such as in video games, virtual avatars, or movie character voice-overs, where they enhance the storytelling or user experience.

Is there an app that can mimic someone’s voice?

Apps and platforms like Synthesys offer the capability to mimic someone’s voice by either uploading voice samples of the target person or selecting from a library of pre-existing, realistic voices. These tools have practical applications in content creation, offering content creators the ability to produce high-quality audio content or voiceovers for videos without having to hire voice actors, pay millions to celebrities for voice overs, or bring historical characters back to life!

Is it possible to deepfake audio?

Yes, with tools like Synthesys, anyone can do it. It uses advanced artificial intelligence (AI) and deep learning technologies to help you do just that, even if you have no tech background.

Deepfake audio, or synthetic voice generation, leverages neural networks to mimic the voice of a specific individual, creating realistic and natural-sounding speech from text inputs. This technology analyzes audio samples of the target voice, learning its unique characteristics, tone, speech pattern, and nuances to produce new audio content that sounds like the original speaker.

Is voice AI safe?

Deepfake voice technology, which encompasses everything from voice assistants to deepfake audio generation, is generally considered safe when implemented with robust data privacy measures and used responsibly. The safety of voice AI hinges on several factors:

Data Privacy and Security: Ensuring that voice data and generated content are securely stored and transmitted within speech tools is crucial. Companies developing voice AI technologies often invest in encryption and other security measures to protect users' audio recordings from unauthorized access.
Ethical Use and Regulations: The ethical use of voice AI, particularly concerning consent and transparency in using human voices of real people, plays a significant role in its safety. Using voice AI in a manner that respects privacy rights and adheres to relevant laws and guidelines can mitigate risks associated with its misuse.
Responsible Application: The context in which voice AI is used significantly affects its safety. For example, deploying voice AI for accessibility features, customer service enhancements, or creative projects is generally safe and beneficial. However, using voice AI generators for impersonating individuals without consent or for fraudulent purposes poses significant legal and ethical issues.
Awareness and Education: Educating users about voice AI and audio deepfakes, including its potential benefits and risks, empowers them to make informed decisions about their engagement with these deepfake technologies. Understanding how to recognize and protect against potential misuse, such as phishing attempts using synthetic voices, is part of ensuring safety.
Technology and Policy Evolution: As voice AI technology evolves, so too do the policies and regulations governing its use. Continuous updates to legal frameworks and industry standards are necessary to address new challenges and ensure the technology surrounding synthetic media remains safe for users and commercial purposes.
