The rise of AI voice agents offers immense potential to transform how we interact with technology. However, for this revolution to be truly successful, it must be inclusive. AI voice agent APIs, the building blocks behind voice experiences, need to be designed with accessibility in mind, ensuring everyone can benefit from this technology.

The Human Story Behind the Technology

What is a voice? It is more than sound — it is identity, connection, and a fundamental part of who we are. Losing it can be devastating. This was the reality facing Richard, a man diagnosed with ALS, whose journey became the catalyst for a technological revolution.

Richard’s desire to preserve his voice for his family, and the inadequacy of robotic solutions available, revealed a profound unmet need. This inspired Arsène Lavaux Santonacci, a visionary growth hacker, who partnered with technologist Jean Marie Tassy Simeoni to create SilenceSilence.ai — a company dedicated to restoring authentic human voices.Designing Inclusive AI Voice Agent APIs

A Voice Demonstration that Stunned Audiences

In a live segment on French television’s Good Morning Business (BFM Business channel), Arsène Lavaux showcased their technology by playing two audio clips: one from Dr. Alexia Mattei, a laryngologist, and another generated entirely by their AI.

The hosts were astonished. The AI-generated version was indistinguishable from the original, confirming the fidelity and realism of SilenceSilence.ai’s innovation.

Technology Born from Human Need

Unlike conventional text-to-speech systems, SilenceSilence.ai uses proprietary multi-agent AI™ to capture and reproduce the richness of human voices. Their system includes:

• Extractor Agent: Captures just 10 seconds of natural past voice

• Cleaner Agent: Enhances audio quality with self-supervised learning

• SiSiPrinter Agent: Creates a deep digital fingerprint

• Impressionist Agent: Restores unique vocal identity

• Magnifier Agent: Ensures fidelity and accuracy

• Opera Agent: Adds natural emotion, prosody, and timbre

• Coach Agent: Orchestrates the entire process for real-time performance

The result is not just synthetic sound, but a true digital twin of the human voice.

Connecting Brains, Voices, and Languages

The conversation expanded to how this technology could evolve further. Arsène referenced Synchron, a pioneer in Brain-Computer Interfaces (BCIs), highlighting a future where brain signals could be directly translated into a person’s restored voice.

Bence Csernak broadened the discussion to conversational agents and multilingual restoration, suggesting a world where lost voices could be returned across languages, breaking barriers in communication.

Ethics and Governance in Voice AI

With such powerful technology comes responsibility. The discussion emphasised the urgent need for:

• Consent frameworks to ensure ethical use

• Provenance protocols to combat deep fakes

• Regulatory guardrails like the EU AI Act for high-risk systems

Without these safeguards, risks such as identity fraud and psychological harm could undermine trust in the technology.

Agentics Conversations: A Movement for AI for Good

This webinar was the first of the Agentics Foundation’s London and French Chapter series, focused on exploring Agentic AI for societal and business transformation. The discussion highlighted how meaningful technology emerges from human stories, not hype.

💡 Key takeaway: The most profound technologies are those that restore dignity, identity, and connection.
