Purported AI-Cloned Voice Depicts Kenyan President William Ruto Speaking French in Viral Video

A purportedly AI-manipulated video widely shared on TikTok and Facebook presents Kenyan President William Ruto speaking in French during a speech in Tokyo on February 7, 2024. A reported reverse image search confirmed the original footage shows Ruto speaking in English to the Kenyan diaspora. The reportedly manipulated version used AI-generated French audio over the original video, making it a case of voice cloning rather than a full audiovisual deepfake.

Risk classification

• Primary risk domain: 3 Misinformation
• Primary risk subdomain: 3.1 False or misleading information

The incident involves an AI-generated deepfake video that falsely depicts the Kenyan President speaking French, leading to misleading information spreading on social media.

Causal factors

• Entity: Human
• Intent: Intentional
• Timing: Post-deployment

The deepfake video was intentionally created and shared by human actors using post-deployment AI voice cloning tools to mislead the public.

EU AI Act risk tier

• Risk tier: 3 Limited Risk

Limited Risk: The system is used to generate AI-generated content such as deepfakes, which under the EU AI Act triggers specific transparency obligations to inform users.

AI system and alleged parties

• AI system: None named
• AI purpose: Voice Generation; Translation
• Behaviour type: Tool
• Alleged developer: Unknown voice cloning technology developers, Unknown deepfake technology developers
• Alleged deployer: Unknown actors manipulating footage of William Ruto, Unknown actors
• Alleged harmed parties: William Ruto, General public of Kenya

Epistemic

Reported: The report explicitly describes epistemic harm in the form of an AI-generated deepfake video that misled social media users into believing the Kenyan President speaks French.

Directly caused: The AI voice cloning tool directly generated false French audio of President Ruto, which was shared across multiple Facebook and TikTok posts.

Indirectly caused: The spread of the video led to social media users believing and commenting that President Ruto can speak French.

Inferred additional harm: It is likely that many more social media viewers were exposed to and misled by the video before it was fact-checked, contributing to a slight erosion of shared truth online.

• People reportedly harmed: 1
• People reportedly exposed: 5

Potential causes

Technology

• Advanced AI Voice Synthesis: Voice software advances made the translated speech sound highly convincing.
• Deepfake Translation Tools: AI tools enabled seamless translation and voice-cloning in foreign languages.

Data Inputs

• Original Video Exploitation: Authentic footage of Ruto speaking in Japan was used as the input source.

Human Factors

• Social Media Sharing Behavior: Users shared the video across platforms without verifying its authenticity.
• Credulity of Online Audiences: Viewers believed the deepfake was real due to its convincing nature.

Process and Methods

• Inadequate Platform Filtering: Social media platforms lacked automated tools to flag synthetic media.

Regulatory Environment

• Lack of Deepfake Regulations: Absence of strict legal frameworks governing the spread of AI deepfakes.

Information quality

• Classification confidence: High
• Reason for confidence: The fact-checking report clearly identifies the source video, the nature of the AI manipulation (voice cloning/deepfake), and the platforms where it circulated. There is no ambiguity about the falsity of the video or the technology used.
• Ambiguities identified: The specific AI tool used to clone the voice is not identified.

An AI-generated deepfake video depicted Kenyan President William Ruto speaking French instead of English. While the incident represents a low-harm showcase of voice-cloning technology with minor national security impact, it highlights the growing ease of generating convincing foreign-language deepfakes of political leaders.

• Overall national security impact: Minor
• Response level: Moderate
• Scope: Single nation
• Primary target: Kenya
• Alleged perpetrator: Unknown

Threat characteristics

• Imminence: Long-term. The incident is resolved and represents a minor, ongoing strategic concern regarding deepfake capabilities rather than an active crisis.
• Autonomy: Human-controlled. The AI voice cloning tool was directly operated by human users to generate the specific translation and voice.
• Novelty: Established threat. AI voice cloning and deepfakes of political figures are established threats with numerous prior occurrences globally.

Impact by dimension

• Physical security: Negligible. No physical security or critical infrastructure threats were identified in connection with this incident.
• Information security: Minor. Involves an AI-generated deepfake of a head of state, but the content was low-harm and lacked indicators of a coordinated or sophisticated state-sponsored information operation.
• Sovereignty: Negligible. The incident did not disrupt core government functions, electoral systems, or state authority.
• Economic security: Negligible. No impact on economic stability, financial systems, or strategic technological competitive advantage.
• Societal stability: Negligible. The misinformation was minor and did not threaten social cohesion, civil liberties, or population safety.
