GAILLAC, France — Guilhem Gallart used to speak with a
thick, southern French accent, his voice deep and slightly nasal, topped by a
faint lisp.
Then, in 2015, he was diagnosed with amyotrophic lateral
sclerosis, or ALS, an incurable neurological disease that slowly paralyzed his
muscles from head to toe, leaving him bedridden and forcing him to use a
voice-synthesizing computer program to speak.
Now his family jokes with him that he sounds like a GPS
device. His wife and two daughters, Gallart said, sometimes call his old
cellphone number just to hear his voicemail greeting.
Losing his distinctive voice, he said, has felt like
surrendering an essential part of himself, as sound has been his life’s
passion. Better known as Pone, he is a music producer and beatmaker who once
belonged to one of France’s most popular old-school rap groups, the Fonky
Family.
In a bid to recapture his signature vocal sound, Pone, 50,
has embarked on a slightly quixotic and still-unfinished quest. Because there
were not enough old recordings of his voice to feed into a computer and create
a synthetic replacement, he asked a comedian to record an imitation of what he
used to sound like — and used that as a basis instead.
“A voice is a very personal thing”, Pone said, propped up in
bed at his home in Gaillac, a small town near Toulouse in southwestern France.
The way you talk “says volumes about your character”, he added, instantly
conveying so much of who you are — even if, as he jokingly described his voice
in a documentary about his life, he “really sounded like an idiot”.
In 2020, he contacted Marc-Antoine Le Bret, a 37-year-old
comic known for celebrity impressions, asking for his help in creating a new
voice to match his old one.
“The challenge was absolutely crazy”, Le Bret recalled
thinking. He had never met Pone but immediately agreed. “It’s the most
beautiful challenge of my lifetime”.

Le Bret immersed himself in old audio and video recordings
of Pone, like clips from a family vacation to Morocco. He also watched footage
of Pone’s band.
Pone did not sing or rap in the Fonky Family, which sold
hundreds of thousands of albums in the 1990s and 2000s with fiery raps about
the hardscrabble streets of Marseille. But Le Bret listened for snatches of
Pone’s voice in interviews, behind-the-scenes footage of concerts and studio
chatter in recording sessions.
Le Bret next worked on refining his impression. But it
wasn’t easy.
Pone was born and raised in Toulouse, where he fell in love
with hip-hop as a teenager, before moving to Marseille. The two cities have
slightly different but equally strong accents, with the silent “e” not always
so silent. (The pronunciation of “Pone” varies from Paris to the south, but the
“e” is silent in both locales.)
Le Bret had to capture Pone’s tone, too, and said he had
“tried to absorb” Pone’s way of expressing himself, without slipping into
caricature. “He’s a wisecracker, he loves irony, and that was important”, he
said.
Getting the intonation right was essential to Wahiba
Gallart, Pone’s wife, and the last person who could understand him before he
switched to the impersonal, digitally generated voice.
“Sometimes he’ll tell us something, and the computer’s tone
is flat, cold”, she said. That makes him sound more abrupt than intended. “It
was important for him to recover as much of his former self as possible, for
our daughters”, she added.
Once Le Bret felt his impression was close enough, he voiced
about 250 stock phrases in a recording studio, many of them nonsensical
sentences designed to provide the right balance of phonemes to feed a program
designed by CandyVoice, a digital voice processing and synthesizing company.
Gallart attended the three-hour session, correcting and
guiding Le Bret. Pone and his family could hardly wait for the results.
Family is Pone’s pillar. His parents and half-siblings often
visit the home in Gaillac, where wedding and vacation shots hang not far from
gold and platinum records celebrating the rap and R&B hits he produced in
his solo career after the Fonky Family broke up in 2007.

through a computer that makes him sound robotic.
His daughters — Naïla, 15, and Jasmine, 12 — often clamber
onto his bed to chat, watch movies or play video games.
And last year, the daughters’ smiles grew wide as they
gathered to listen to Pone use the new voice for the first time — a moment
captured by a national television news crew.
The results earned a mixed review.
The voice was synthetic but distinctly southern and very
close to his original one. Unfortunately, it was also buggy. Longer sentences
were garbled; syllables were occasionally dropped. Pone was quick to spot the
glitches.
“I was dealing with a sound engineer, an expert”, said
Jean-Luc Crebouw, the founder of CandyVoice. He said Pone had grown used to the
neutral-sounding synthetic voice, which made the kinks in the new one stand out
even more.
But the experiment was successful enough that Pone said he
wanted to keep going, and he has contacted other companies to fine-tune the new
voice.
“Using my actual voice was a plus”, he said. “I was able to
express myself again”.
New artificial intelligence and computer-generated speech
tools are offering hope to patients with speech-impeding diseases, although
these approaches typically require people to either still be able to speak or
have a fairly large library of recordings of their voice.
Pone, who lost his voice before these technologies were
available, needed the more creative solution of partnering with Le Bret. In
recent weeks, he has tried different AI tools, but the results were “very
disappointing”, he said, and for now, he has reverted to his old synthetic
voice.
When he wants to speak, an infrared sensor tracks his eyes
as they move across a keyboard on a screen, enabling him to write text that is
then read out in a monotone. The process is slow. During an interview, minutes
of silence between each answer were broken only by the rhythmic whooshing of
his artificial respirator and the occasional beep of his gastric feeding
machine.
The challenge Pone set himself to recapture his voice is not
the only one he has taken on since being diagnosed eight years ago with a
disease whose mean survival time, according to the ALS Association, is two to
five years.
Pone can no longer spend hours improvising with samples in a
studio. But since his diagnosis, he has started a music label, and using his
eyes to operate music software, he has released several albums, including one
based entirely on Kate Bush samples. He also produced a mix for the handover
ceremony of the Paralympic Games, held in Tokyo in 2020 and scheduled for Paris
in 2024.
He started an “ALS for Dummies” website and wrote a recently
published autobiography. Pone said he had always been hyperactive. “Now”, he
added, “I’m just in more of a hurry”.
Since the diagnosis, Pone said he had become a “better
version” of himself, uncluttered by fleeting distractions and focused on the
essentials.
ALS “left me what mattered most”, he writes in his
autobiography. “My mind and my heart”.
He converted to Islam in the mid-2000s, and he said his
faith had helped him find inner peace. “It’s all about acceptance”, he said.
“And I have accepted”.
He does miss life’s tactile pleasures, like walking on a
sandy beach or hugging a loved one. And landing a punchline is hard when you
have to type it with your eyes.
While the disease has stolen his speech and much else, he
and his family said it had only strengthened their bonds.
Jasmine is too young to remember what her father sounded
like and said she was excited to hear a better version of his “new” voice.
Still, the current one has grown on her. “When he is joking or is happy, I
almost feel like the intonation changes,” she said.
“It’s not really the voice of a robot anymore”, she added.
“It’s my dad’s”.
