Oscar Darko-Sarfo sounds smitten by his new job as a barber — an enormous break for a 22-year-old who as soon as doubted he would discover work. He was born with a cleft palate, which impairs his capability to talk clearly; it’s not all the time straightforward for listeners to know him.
Darko-Sarfo is one in every of 20 Ghanaians testing out synthetic intelligence-enabled know-how developed by Google to assist folks with non-standard speech. After talking in English right into a smartphone skilled to recognise his speech patterns, a feminine, American-accented voice proclaims: “I’m working as a barber. I love to do Afros.”
The app, nonetheless in prototype, has improved Darko-Sarfo’s capability to speak, he says — and with it his confidence. Along with buying a job, he has lately discovered a girlfriend.
Google’s computerized voice recognition know-how, referred to as Venture Relate, is a tiny instance of how AI may also help sort out issues in what researchers discuss with as “low-resource settings”.
AI is being marshalled in a number of fields on the African continent, which incorporates a number of the poorest international locations on the earth: in Zambia, to assist enhance medical diagnostics; in Kenya, to allow farmers to establish crop illness; and in Ethiopia, to tailor training supplies to pupils’ wants.
Within the 18 months since AI grew to become front-page information, there was in depth dialogue of the way it will change society: its impact on jobs, on elections, on science, even what it means for the way forward for humanity. That dialog has centred largely on the wealthy international locations the place it has been developed.
Darko-Sarfo’s case illustrates most of the prospects this new know-how provides for Africa and in growing nations extra typically, but additionally the pitfalls. On one hand, an AI-powered machine has helped him overcome his speech points in a rustic with restricted well being assets and only a handful of speech therapists. On the opposite, Google’s know-how just isn’t but obtainable in his first language, Twi Asante. There isn’t any assure will probably be extensively adopted.
Gifty Ayoka, a Ghanaian speech therapist, whose NGO Speaking Tipps is testing the know-how along with College School London’s World Incapacity Innovation Hub, is cautiously optimistic in regards to the function AI can play in her nation and others prefer it. “If we are able to actually embrace this, it would make issues simpler for folks,” she says.
However she additionally worries that Ghana’s state and society will be unable to correctly take up a know-how developed overseas. “With out consciousness and coaching, plus native language and cultural help, no software — nevertheless intelligent — goes to be helpful,” she says.
Proponents argue that AI may also help poorer societies “leapfrog” complete phases of growth in the identical means that many international locations, missing landline infrastructure, enthusiastically adopted cellphones within the early 2000s. As soon as handsets unfold, new improvements adopted, permitting folks to make use of their gadgets for all the things from monetary transactions to paying for entry to solar energy.
“Nicely-run digital techniques make states extra succesful,” mentioned Microsoft co-founder Bill Gates in an interview with the Financial Times final 12 months, wherein he extolled the virtues of growing nations embracing the digital revolution.
To optimists, AI presents a once-in-a-generation alternative to go one step additional. Machine studying, they argue, can turbocharge the leapfrogging phenomenon by placing revolutionary instruments into the fingers of people, companies and states.
“I consider within the transformational impact of tech,” says Yordanos Asmare, an Ethiopian who’s head of expertise at A2SV (Africa to Silicon Valley), a US-based affect incubator that seeks to develop African AI capabilities.
However many, together with Asmare, fear AI may have exactly the alternative affect, amplifying the benefits of richer nations which have extra computational energy and pc engineers, and leaving different international locations trailing.
Shiny Simons, co-founder of Imani Centre for Coverage and Schooling, an Accra-based think-tank, says Africans produce lower than 0.5 per cent of machine studying and large-language fashions. “We’re already beginning out at a a lot decrease base in comparison with the remainder of the world,” he says. “The AI leapfrogging concept fully dissolves, as a result of in AI you’re already marginalised.”
James Manyika, Google’s senior vice-president for analysis, know-how and society, who grew up in Zimbabwe, says that the dangers of falling behind make it all of the extra necessary for the continent to forge forward. “AI presents a chance too vital to disregard for Africa,” he says.
In Could, Microsoft president Brad Smith gave a speech in Nairobi to mark a $1bn funding in Kenya. Together with G42, an Abu Dhabi AI firm, Microsoft is constructing what it calls a “complete package deal of digital investments” together with a geothermal-powered information centre and an innovation lab.
AI, Smith informed his viewers, was a know-how corresponding to the printing press and electrical energy. And whereas Africa partly missed out on earlier transformative applied sciences — 142 years after Thomas Edison’s invention, 43 per cent of Africans nonetheless lack entry to electrical energy — the identical needn’t occur with AI, he argued. “One must deliver three issues collectively: human capital, monetary capital and technological innovation.”

Whereas the challenges of making an AI “know-how stack” — information centres, AI fashions and builders — have been appreciable, he mentioned, they have been achievable. And AI performed to the strengths of a continent the place the median age is nineteen, the youngest on the earth.
Google has additionally made an AI push within the area, opening an AI analysis centre in Kenya in 2022 so as to add to the one it constructed throughout in Ghana in 2018, which was the primary of its form in Africa. Searching for a enterprise alternative, entry to expertise and an opportunity to affect how a continent that may have 2.5bn folks by 2050 engages with the know-how, it has additionally dedicated to spend $1bn on digital infrastructure. Investments embrace a cable linking a number of east and central African international locations to Australia and one other from Portugal to South Africa.
At Google’s AI analysis centre in Accra, the place Jason Hickey leads a group of software program engineers recruited from throughout Africa, the temper is upbeat. “It is a transformative know-how,” says Hickey. On the sixth ground of a rented workplace constructing, Google software program engineers are engaged on AI-powered instruments to, amongst different issues, predict famines and map buildings, together with casual settlements that may be invisible to satellites.
MohamedElfatih MohamedKhair, a software program engineer from Ethiopia, explains how Google is constructing an AI mannequin to watch flash floods in actual time. Elements of Africa have a paucity of climate radars; to deal with the issue, Google has designed a mannequin that mixes information from two forms of satellites.
“We use AI to fill within the gaps. That’s our hack,” says Hickey. Removed from being a bargain-basement model of better-resourced techniques, he says, the AI mannequin beats normal strategies. “Sure, we need to do it on a budget. However we’re really in a position to get higher forecasts from AI.”
One space the place consultants see massive potential advantages is training, each by means of interactive studying and, extra broadly, by educating in related languages. There are not less than 1,000 languages in Africa, but, due to the legacy of colonial historical past and the languages wherein instructional supplies are produced, many college students study of their second or third tongue, placing them at an enormous drawback.
“In Africa, folks communicate their language at residence however study all the things in English or French. All their photos and books are western,” says Simons, the Ghanaian think-tanker. “So how will we use pure language processing to generate extra native content material, to create textbooks in native languages and to report oral historical past?”
A2SV, the affect incubator, has developed an AI-powered “personalised studying” tutoring programme referred to as SkillBridge, which makes use of Amharic and Afan Oromo, the 2 most generally spoken languages in Ethiopia, to educate pupils taking the nation’s college entrance examination. Of almost 675,000 college students who sat the take a look at this 12 months, solely 5.4 per cent handed.
“It raises plenty of questions across the high quality of training, but additionally about what are you going to do with all these younger folks and in regards to the productiveness of the nation,” says A2SV’s Asmare. The hope is that SkillBridge can enhance outcomes.
Healthcare is one other space with potential, argue AI lovers. In lots of international locations, ultrasound tools is simply too costly and skilled sonographers are in brief provide. Ninety-five per cent of pregnant ladies in Africa don’t have any entry to scanning, in keeping with Angelica Willis, a Google AI researcher.
The corporate has developed an AI mannequin to analyse information collected from cheaper transportable ultrasound tools deployed by novice operators. A study in Zambia discovered that AI may assess gestational age and foetal malpresentation from “blind sweep ultrasounds” to the identical normal as skilled sonographers utilizing normal tools. If it have been adopted extra extensively, this might save many lives.
Whereas AI guarantees a lot, some worry that the know-how — like many earlier than it — couldn’t solely replicate present world inequalities, however exacerbate them. “We name it know-how amplification concept,” says Catherine Holloway, a professor of interplay design and innovation at UCL.
Google’s Manyika, who can be co-chair of the UN’s high-level advisory physique on AI, acknowledges the hazard of what he calls an “AI divide”. “AI is computer-intensive and we all know that machine and information prices [in Africa] are the best on Earth,” he says.
Simons argues there are limits to tech’s capability to patch up dysfunctional governance techniques. “For 80 per cent of issues, AI would be the cherry on the highest,” he says. However in international locations that lack a functioning well being system, respectable roads and energy, or a fairly accountable state, there are few shortcuts, he says. “No person wants cherries in the event that they don’t have already got the cake.”
Simons additionally factors to acquainted anxieties — the menace to information privateness and possession and the chance that AI could possibly be exploited by dangerous actors, together with states. In 2020, Ghana, regardless that it has a thriving democracy, bought 10,000 safety cameras from China as a part of a face-recognition system. Nonetheless creatively civil society makes use of AI, Simons says, “tyranny [could be made] a lot simpler”.
Some campaigners are additionally involved a couple of potential “information seize” wherein a couple of massive, nearly solely US, firms are accumulating information from Africa and constructing instruments that they will promote elsewhere. Campaigners have pointed to what they are saying is the exploitation of African labour in data centres, the place folks working for as little as $2 an hour are coaching AI fashions for large tech corporations.
“It could possibly be Ghanaians feeding ChatGPT, for instance, and that information is within the US,” says Asmare, who joined A2SV after transferring from Ethiopia to review at Stanford and work in Silicon Valley, and who now lives within the US. “The place does that information go? Are governments fascinated with that?”
There may be additionally the difficulty of Africa’s astonishingly wealthy number of languages. Till now, most giant language fashions have been constructed utilizing English databases, with all of the built-in inequalities that suggests. Some African languages are primarily oral with little digital textual content, reminiscent of Wikipedia entries, to feed into pure studying processing fashions.
SEE Africa, a Tanzanian NGO, has designed a voice-enabled interactive app to assist rural ladies navigate the business alternatives of rising a extremely nutritious kind of candy potato. It wanted its app to work in Swahili. But though the language is spoken by some 200mn folks throughout east Africa, there aren’t adequate information units for AI fashions to work on, says EM Lewis-Jong, director of Widespread Voice, an open-source useful resource funded by the Mozilla Basis, a non-profit group working to maintaining the web accessible.
“The Anglo-centrism of the web is a form of colonialism in one other kind,” she says. “Heritage, tradition, the actual options of your existence, are so deeply intertwined with language,” she says. Even one thing as apparently common because the thumbs-up signal fails to cross linguistic boundaries: in a number of African languages, it may be an insult.
So Widespread Voice is harnessing AI to sort out the difficulty. People or organisations reminiscent of SEE Africa can add as much as 1,000 hours of speech in their very own language (or mixture of languages) on to its platform, both studying out sentences or acquiring copyright-free materials from native radio stations and the like to educate pure language fashions.
“Speech know-how has enormous potential to be impactful in low-literacy communities,” Lewis-Jong says. “AI may genuinely make language a bridge and never a barrier.”
Equiano Institute, a South African AI think-tank, has ambitions to construct an African-owned and operated giant language mannequin. “Simply as ChatGPT offers an LLM mannequin, we need to present that answer in Africa,” says Daniel Akinmade Emejulu, who chairs Equiano’s advisory board.
Google, too, is constructing giant information units in a number of African languages from its Ghana analysis centre. “Earlier this 12 months, we added one other 110 languages, of which a couple of third have been African,” says Google’s Manyika.
Regardless of the challenges, Manyika says he stays satisfied that AI provides a singular likelihood for poorer international locations to “stage up” by flattening entry for people and companies to instruments and information, and by offering states with the means to sort out massive societal challenges.
“I basically consider that AI represents a chance not just for the world,” he says, “however for growing areas like Africa particularly.”
Huge corporations reminiscent of Google, Microsoft and Amazon, which says it’s investing $1.7bn to develop cloud and AI providers in Africa, will proceed to spend money on the continent — albeit with what are, by their requirements, comparatively modest quantities.
What affect AI has, nevertheless, says Simons of Imani Centre, won’t ever be a purely technological drawback, however a query of how it’s absorbed by states. Know-how, he says, can solely enhance folks’s lives if it could actually cross the “interface” between cyber area and real-life, from what he calls “the world of bits to the world of atoms”.
Hickey cites the instance of nations deploying Google’s AI climate forecasts. “In the end, we are able to present the knowledge. The ultimate step of engagement with farmers or people who find themselves affected by floods must be carried out by means of efficient engagement with the neighborhood,” he says.
If governments in wealthy international locations are struggling to grapple with the results of AI, nonetheless much less legislate for it, in growing societies the state of affairs is much more difficult. Simons says that except states are utilizing AI themselves, they can’t hope to know or regulate it.
Ayoka, the banker turned speech therapist, is annoyed at what she sees as a scarcity of ambition from Ghana’s authorities regardless of its digital-first rhetoric. “All this tech is so superior, however our authorities is sleeping.”
Many African governments speak recreation about being open to AI, agrees Asmare at A2SV, however she want to see extra strategic considering. “My query is, do you might have the security guardrails to verify your individuals are not exploited, and that these investments are according to what the nation and the folks want?”
Google’s Manyika argues that Africans are best-placed to steer use of the know-how of their international locations. “What Africa does with AI must be Africa-led,” he says.
