Preface

The rapid development of artificial intelligence has brought so-called voice cloning—the strikingly realistic reproduction of human voices—out of the lab and into everyday life in recent years. What once sounded like science fiction today is available to anyone with just a few clicks.
This technology opens up fascinating possibilities but also carries significant misuse risks—from identity theft and fraud to the spread of misinformation.

​
Opportunities of Voice Cloning

  • Accessibility: Restoring a voice for people with speech loss
  • Creative Projects: New possibilities in film, gaming, and media production
  • Digital Services: Personalized voice assistants and services
  • Efficiency Gains: Automated speech production for various applications

​
Risks and Challenges

A person’s voice thus becomes a valuable asset to be protected, similar to fingerprints or personal data. With this guide, we aim to give you an overview of the most important legal framework conditions. You will learn:
  • Which laws and regulations exist to protect your voice
  • When and how consent is required
  • What rights you have as a data subject or user of this technology
  • How to use voice cloning responsibly and in compliance with the law

1. Introduction

​
1.1 What is Voice Cloning?

Voice cloning refers to a technology that digitally copies and reproduces a person’s voice. Using artificial intelligence (AI)—particularly neural networks and machine learning—an artificial voice is generated that closely resembles the original in sound, pitch, accent, and other distinctive characteristics.
1

Data Collection

Speech samples of the target person are collected and analyzed
2

AI Training

This data serves as the basis for an AI model that recognizes and replicates individual speech patterns
3

Voice Profile Creation

The resulting digital voice profile can then speak any text as if it were coming from the original person

​
Areas of Application

  • Personalized voice assistants and chatbots
  • Dubbing in films and video games
  • Audiobooks, podcasts, and e-learning
  • Accessibility for people with speech or reading disabilities
  • Customer service and individual brand voices

​
1.2 Technical and Societal Significance

Voice cloning is based on advanced technologies such as neural networks, deep learning, and machine learning. Even a few seconds of audio material can be enough to create a detailed voice profile.

​
Societal Significance

Positive Applications:
  • Personalization of digital services
  • Scalability of media content
  • Improvement of accessibility
  • Authentic voicing of historical figures
  • High-quality reading voices for visually impaired people

​
2.1 Protection by the General Personal Rights (APR)

The General Personal Rights (APR) protect the voice as a central identifying feature of a person under German law.

Constitutional Basis

Art. 1 para. 1 and Art. 2 para. 1 Basic Law (GG)

Civil Law Implementation

§ 823 para. 1 BGB as “other rights”

​
Key Aspects of Protection

  • Right of self-determination: Control over recording, publication, and imitation
  • Moral and economic interests: Protection from exposure and economic harm
  • Case law: Higher Regional Court Hamburg (1989), Federal Court of Justice “Marlene Dietrich” (1999)
Anyone who records, publishes, or imitates another person’s voice without their consent—e.g., via AI voice cloning—can be subject to injunctions and damages claims.

​
2.2 Protection under Data Protection Law (GDPR)

The GDPR protects the voice as a biometric and personal data.

​
Rights of Data Subjects

Right of Access

Art. 15 GDPR: Right to information about stored voice data

Right to Erasure

Art. 17 GDPR: “Right to be forgotten”

Right to Restrict Processing

Art. 18 GDPR: Right to restrict processing

Right to Object

Art. 21 GDPR: Objection to processing

​
2.3 Neighboring Rights for Speakers and Performers

Neighboring rights protect performing artists such as speakers, musicians, or actors (§ 73 UrhG). Scope of rights:
  • Right to recognition and attribution
  • Control over reproduction and distribution
  • Claim to appropriate remuneration
  • Duration of protection: 50-70 years from publication
Copyright does not protect the voice itself, but only the specific recording or artistic performance of a voice.

​
3.2 Neighboring Rights under § 73 UrhG

Protection for performing artists with comprehensive exploitation and moral rights.

​
3.3 Original Recordings vs. AI-Generated Voices

Comprehensive Protection:
  • Copyright protection
  • Neighboring rights (§ 73 UrhG)
  • Exploitation rights
