In a remarkable leap for artificial intelligence in Nigeria, University of Lagos (UNILAG) student Saheed Azeez has developed YarnGPT, a groundbreaking text-to-speech (TTS) AI model that reads aloud in an authentic Nigerian accent.

A Passion for AI Innovation

Azeez first gained attention in November 2024 when he created NaijaWeb, a dataset of 230 million GPT-2 tokens based on discussions from Nairaland. At the time, he downplayed the complexity of the project, describing it as “just web scraping.” However, his latest endeavor, YarnGPT, showcases an even more ambitious leap into AI-driven speech technology.

“In the global AI landscape, lifelike voice synthesis is becoming common, but creating a model that accurately captures the nuances of a Nigerian accent is a major technical feat,” Azeez explains.

Challenges and Breakthroughs in Building YarnGPT

Building an AI model that truly reflects Nigerian speech patterns required extensive data collection and rigorous algorithmic refinement. Azeez leveraged audio from Nigerian movies, extracting both speech and subtitles, but soon encountered a challenge: low-quality transcriptions and inconsistent audio data.

“The biggest problem with AI development in Nigeria is access to high-quality data,” Azeez notes. “Replicating foreign AI models isn’t impossible, but the lack of structured datasets makes it incredibly difficult.”

To overcome this, he turned to Hugging Face, an open-source machine learning platform, integrating their high-quality datasets with his Nigerian audio samples to train YarnGPT.

Overcoming Technical and Financial Barriers

Training AI models requires significant computing power. Without personal access to a high-performance GPU, Azeez initially relied on Google Colab, spending $50 (₦80,000) in cloud credits—only for the model to fail.

“The first attempt didn’t work, and the cloud credits were wasted. It was frustrating,” he recalls.

Determined to find another way, he studied Oute AI’s autoregressive text-to-speech models, which generate words one at a time in a predictive sequence—similar to how ChatGPT forms sentences. Implementing this approach, he adapted SmolLM2-360M, a language model from Hugging Face, and incorporated speech functionality, requiring complex algorithmic modifications. The final training process lasted three days and cost another $50.

The Science Behind YarnGPT: Tokenizing Nigerian Speech

Large Language Models (LLMs) process information numerically through tokenization—breaking down words into smaller segments assigned numerical values. However, tokenizing audio is vastly different.

“Unlike text, which has clear breaks between words, audio is continuous,” Azeez explains. “The AI has to convert sound waves into structured sequences the model can process, like assembling tiny puzzle pieces into a full speech pattern.”

By employing advanced wave tokenization techniques and utilizing Nigerian linguistic datasets, Azeez successfully trained YarnGPT to read aloud in Nigerian English, as well as Yoruba, Hausa, and Igbo.

YarnGPT Goes Viral

Despite being a self-proclaimed “nerd,” Azeez knew that technical brilliance alone wasn’t enough—he needed public attention. With the help of friends, he shot a two-minute demo video showcasing YarnGPT in action. The clip quickly gained traction on social media, garnering 138,000 views on X (formerly Twitter) and attracting industry leaders like Hellicarrier Co-founder Timi Ajiboye.

Creating the video, however, came with its own set of hurdles.

“I called my friend Aremu, who helps with logistics, and told him we needed to make a video. We borrowed a camera from another friend, used someone else’s house as a backdrop, and even rearranged their living room,” he laughs. “Their mom wasn’t too happy when she got back.”

The effort paid off. YarnGPT’s popularity surged, with users praising its ability to pronounce Nigerian names correctly and read in multiple local languages. Potential applications include:

• Content Creation: Voice-overs for videos, audiobooks, and advertisements in Nigerian accents.
• Navigation Systems: Localized voice directions for platforms like Google Maps.
• Accessibility Tools: AI-powered speech assistance for non-English speakers.

Nigeria’s AI Future: A Long Road Ahead

Despite the ingenuity of developers like Azeez, Nigeria lags behind in the global AI race. While the U.S. government has committed over $500 billion to AI development, Nigeria’s investments remain minimal.

Azeez acknowledges the gap but remains optimistic.

“We’re far behind, no doubt. The leading AI models today—OpenAI’s, China’s—are trained with vast computational resources we simply don’t have. But I believe there’s a way forward. Instead of reinventing the wheel, we should focus on localizing AI for Nigerian needs—building models that serve our own languages and accents.”

His vision aligns with Nigeria’s growing interest in AI. Minister of Communications and Digital Economy, Bosun Tijani, has emphasized the country’s ambition to become a key player in artificial intelligence. With talents like Azeez pushing boundaries, the future of Nigerian AI innovation is promising.

YarnGPT stands as a testament to Nigerian ingenuity—proof that innovation thrives even with limited resources. As Azeez continues refining his model, the question remains: will Nigeria step up to support homegrown AI talent, or will these breakthroughs remain passion projects?

For now, one thing is certain: the world is listening, and YarnGPT is making Nigeria’s voice heard.

The TikTok drama is heating up! President Donald Trump dropped a major hint recently, confirming that Microsoft might be in talks to snag TikTok’s U.S. operations. In a casual chat with reporters, Trump said, “I would say yes,” when asked if the tech giant was preparing a bid. He even predicted a full-on “bidding war” over the wildly popular app.

For those who missed it, this all started back in August 2020 when Trump, citing national security concerns, pushed TikTok’s Chinese parent company, ByteDance, to sell its U.S. branch. ByteDance initially approached Microsoft, but their CEO later called it “the strangest thing.” Spoiler: Microsoft didn’t seal the deal. TikTok later leaned toward Oracle as a potential partner, but that fizzled out too.

Fast-forward to now, and Trump claims there’s serious interest in TikTok from multiple buyers. “We’ll see what happens,” he said while addressing a crowd in Florida. “If we can save all that voice and all the jobs, and China won’t be involved… we’ll see what happens.”

Big names like billionaire Frank McCourt and Shark Tank’s Kevin O’Leary have also been floated as potential suitors. Even YouTube megastar Jimmy Donaldson, aka MrBeast, has thrown his hat in the ring after tweeting his interest and getting flooded with investor offers. Yep, TikTok’s future might just have a touch of YouTuber magic.

As for Microsoft, the company has kept things hush-hush, saying they’ve got “nothing to share at this time.” TikTok hasn’t commented yet either.

Meanwhile, Trump’s push to sell TikTok’s U.S. operations isn’t new. Both he and Former President Joe Biden have been pressuring ByteDance for years, citing concerns over user data being linked to the Chinese government. Just last week, Trump signed an executive order delaying a TikTok ban that had briefly knocked the app offline for its 170 million U.S. users.

The clock is ticking for TikTok’s next big move. Could we see Microsoft finally stepping in? Or will another player steal the spotlight? Stay tuned!
