The question

What should you be able to decide about your voice after you’re gone?

Two years ago, a friend asked me to help recreate the voice of her cousin, who had died, so his voice could be heard at his sister’s wedding. (Her account of it ↗)

She wrote the message herself. AI supplied his voice.

At the time, I was mostly thinking about the strange new thing we were able to do. Later, while studying futures thinking, I started wondering about the decision that had never been made.

What if he had been able to decide beforehand what could happen to his voice? Could he have said yes to a wedding message, but no to an advertisement? What if the people making those decisions decades later no longer knew what he meant?

That became the starting point for my second Futures Lab experiment:

What happens when a decision about your voice has to be interpreted by people living in futures you could never have anticipated?

A note on the premise

The Voice Clause is fictional. It is a speculative design device, not a legal instrument. The project uses current technologies, laws, and emerging practices as signals for imagining what might happen next.

What is real / what is imagined

Before going further, it’s worth being precise about where the research ends and the speculation begins.

Exists today

Voice-cloning technology, synthetic speech, documented attempts to recreate deceased people’s voices, emerging digital-replica practices.

Already being defined

Laws, contracts, publicity rights, estate mechanisms, and other frameworks addressing voice, likeness, digital replicas, and postmortem use.

This project

The 2031 Voice Clause, the future scenarios, and the fictional institutions are speculative design devices.

The Voice Clause is fictional. It is not a legal instrument or a universal mechanism for controlling a voice after death.

What does “voice” mean?

Part of the research was simply untangling the word itself. These four things are often treated as interchangeable, and they aren’t.

Recording

A fixed piece of audio.

Voice

The recognizable characteristics of how someone sounds.

Synthetic replica

A system capable of generating speech resembling that voice.

Generated speech

New audio created by the system.

The project became interested in what happens as we move from one category into the next.

A conceptual and technical clarification, not a legal taxonomy.

Method / Look Back to Look Forward

Look back to look forward

I started by looking at how the relationship between a person and a recorded voice has changed.

For a long time, recording meant preserving something that had already happened. Over time, the thing being preserved became larger: recordings, photographs, messages, posts, interviews, enormous archives of ourselves.

Then another possibility emerged: using those materials to construct something that could speak back.

The timeline

2011

IFTF’s Ghosts in the Machine imagined interactive digital emulations of deceased people.

Preservation started becoming simulation.

External research

legacy.iftf.org ↗

2017

Jamais Cascio’s futurist work imagined simulations of the dead answering within the limits of what they had said or written.

The simulation could start answering new questions.

Course material

2019

Voice-cloning signals in my course materials showed how convincing synthetic speech was becoming — and how little source material could be needed.

A recording could become a model for generating new speech.

Course material

Gizmodo ↗

2022

Amazon demonstrated Alexa reading a story in a deceased relative’s voice, from less than a minute of speech.

Synthetic remembrance began to look like a consumer use case.

External research

TechCrunch ↗

2024

Tennessee’s ELVIS Act added voice to protected rights (Tennessee Public Chapter 588 ↗); California’s AB 1836 addressed unauthorized digital replicas of deceased personalities (California Legislature ↗).

Some U.S. states began explicitly extending postmortem protections to voice and digital replicas.

External research

2025

Reuters documented people already using AI-generated voices of deceased relatives and an emerging “grief tech” industry.

The scenario moved from speculation into lived experience.

NOW

This project.

The question moves from whether it can be done to who gets to decide what it means.

This project

There was a pattern here that I couldn’t stop thinking about.

We moved from keeping the recording to reconstructing the speaker.

And once a system can generate something a person never actually said, the question changes.

Method / Signals + Forecasting

From signal to forecast

The course distinguishes a forecast from a scenario. A forecast is a plausible direction built from present signals. A scenario is a specific situation inside that broader future — it puts you in a world and asks what it would feel like.

I wasn’t trying to predict what voice technology will look like in 2047 or 2081. I wanted a working hypothesis to test:

Working forecast — a hypothesis, not a prediction

Voice clauses become a normal way for people to express wishes about synthetic versions of themselves after death.

From there, the method was simple: the document stays the same; the world around it changes.

Method / Futures Triangle

What is pulling, pushing, and holding this future?

Pull of the future

The desire to hear someone again.

Continuity, memory, relationship. A child wants a grandparent’s voice. A family wants one more message. The emotional pull is toward connection.

Push of the present

The technology keeps getting closer.

Increasingly capable voice synthesis, abundant recordings, conversational AI, and commercial development. The distance between a recording and a new sentence spoken in that voice keeps shrinking.

Weight of the past

Older questions remain underneath.

Mourning practices, privacy, inheritance, identity, and ideas about what belongs to the dead. Who can speak for someone who is gone?

The current emergence of grief-tech services and new legal frameworks around voice and digital replicas are part of that changing landscape. (Reuters ↗)

Method / Scenario building

One document. Four futures.

The first version of the idea was simply “write a voice clause.”

The scenario work made me more interested in what would happen after the clause was written. So I kept the document fixed and changed the circumstances around it: four requests, arriving between 2047 and 2081, each one harder to answer than the last.

01

2047

The Request

Situation
A daughter wants a message for her wedding.
What gets difficult
The message was never recorded.
What it tests
Meaning

If the words come from you, but the message never existed, is it still yours?

02

2063

The Inference

Situation
A grandson wants to know what you would have told him.
What gets difficult
The answer was never spoken.
What it tests
Inference

When does reconstruction become invention?

03

2067

The Category

Situation
An archive wants to use your synthetic voice for historical purposes.
What gets difficult
“Historical” and “commercial” no longer fit neatly apart.
What it tests
Commercial category

What happens when an old category no longer fits the world around it?

04

2081

The Inheritance

Situation
An institution wants to preserve your voice after the clause has expired.
What gets difficult
In this scenario, authority passes to the estate after the clause expires.
What it tests
Authority / intent

Who gets to decide what you meant when everyone who knew you is gone?

The cases became a way of watching one decision age.

The document

At the center of the prototype is a fictional Voice Clause, written in 2031. It covers whether the voice can be recreated, who can authorize it, what it can say, where it can be used, commercial use, duration, and what the voice must never say.

Rather than reproduce the whole artifact here, two excerpts matter most — one a rule, one an admission that rules run out.

Voice Clause · §03 — What my voice may say

2031

“My voice may only speak words that I recorded myself during my lifetime.”

Rule

It sounds specific. Then the futures start testing what “my words” actually means. That became the central design constraint: the clause had to stay unchanged.

Voice Clause · §08 — Final instruction

2031

“Where these instructions do not provide a clear answer, I ask the people responsible for interpreting them to consider what I was trying to protect…”

Interpretation

The document contains both kinds of language: rules that try to be precise, and an instruction that admits precision has a limit. The gap between the two is where the project lives.

The progression

The four cases revealed four different kinds of uncertainty. Each future moves the decision one step further from the person who made it.

01

Meaning

A message that fits the permitted setting, assembled from words never meant for it.

02

Inference

An answer to a question the person never answered.

03

Category

A use the document’s categories were never written for.

04

Authority

A decision that outlives everyone who knew the author.

What I said

What I meant

What the future thinks I meant

Who gets to decide

The conceptual spine of the project: each future moves the decision one step further from the person who made it.

In 2047, the daughter’s request fits the permitted setting; the ambiguity is in the message itself. In 2063, the system is answering a question the person never answered — an echo of Jamais Cascio’s futurist work in my course materials, which imagines simulations of the dead eventually extrapolating responses to new problems. In 2067, the use is allowed but the categories no longer fit the world. By 2081, the clause has expired. In this scenario, authority passes to the estate after the clause expires. But the context needed to interpret the person’s intent is gone.

The document is still legible. Its author isn’t available to explain it.

Method / Iteration

One thing I changed

In the first version, I asked the visitor to decide whether each request was ALLOWED, PROHIBITED, or AMBIGUOUS.

It made sense as an interaction. Then I realized it was undermining the premise: the visitor inhabits the person who wrote the clause, and by the time the requests arrive, that person is no longer alive. They don’t get to adjudicate what the document means.

Before

The visitor decides: allowed, prohibited, or ambiguous.

After

The visitor is asked: how would you interpret the clause?

The revised experience then shows the document assessment — which provisions are clear, which are prohibited, and which require interpretation. The people and institutions involved can disagree. The visitor is there to see the dispute, not resolve it.

That small change made the whole project more coherent.

From cases to artifact

I built the experience as a kind of administrative system for something that doesn’t fit neatly into a system.

The visitor moves through:

  1. 01

    The original clause

  2. 02

    A request arrives

  3. 03

    The document is reviewed

  4. 04

    The future changes

  5. 05

    The clause expires

  6. 06

    The document becomes harder to interpret

  7. 07

    The visitor writes their own clause

  8. 08

    Their decisions are tested against future situations

  9. 09

    They generate a document they can save

The artifact uses Bureaucratic Brutalism because the visual language is part of the idea. The interface looks like an archival record, an estate system, a legal document, a government form. There are no futuristic graphics, avatars, or voice effects.

I also deliberately kept the prototype silent. I didn’t want to build a demonstration of voice cloning; I wanted the visitor to think about what a voice means when the technology itself becomes ordinary.

The futures methods

The project grew out of the Institute for the Future’s Futures Thinking specialization. Each method I used fed a specific part of the work:

  1. Look Back to Look Forwardhistorical trajectory
  2. Signalsemerging conditions
  3. Futures Triangleforces shaping the future
  4. Futures Wheelconsequences of a future development
  5. Scenario buildingfour future situations
  6. Experiential Laddertranslating the scenario into an experience
  7. Pledge to Make the Futurevisitor writes a voice clause

What does “voice” actually mean?

There was another question I hadn’t expected to encounter through the project. I started thinking about my own voice.

Portuguese is my first language, and I speak English with an accent. That made the word voice feel less straightforward.

If my voice were reconstructed decades from now, what exactly would need to survive for it to still feel like mine?

The words?
The accent?
The rhythm?
The language?
The pronunciation?
The emotional qualities?

A synthetic reconstruction could preserve the content of what I said while changing something about how I sound. That made me realize that the project isn’t only about whether a machine can reproduce someone’s speech. It is also about what we think is essential to a voice in the first place.

I kept that question here, in the case study, rather than putting my own voice into the artifact. The prototype belongs to a fictional future; this observation belongs to the person making it.

What this project doesn’t try to solve

The prototype deliberately focuses on interpretation, authority, and the passage of time. It does not attempt to solve every question involving voice-model security, model custody, international jurisdiction, contractual enforcement, or deletion and derivative copies. Those are real problems; they just aren’t the ones this experiment is about.

What I learned

I started with a question about consent.

The project became more interesting when I started thinking about interpretation.

A person can write down what they want. They can name who should decide. They can try to anticipate future uses.

The difficulty is that someone else may eventually have to interpret those instructions in circumstances the original person could never have imagined.

The document stays the same.

The requests change.

The meaning keeps moving.

The prototype does not solve that problem. It gives the problem somewhere to happen.
