How Taslim Okunola brought Nigerian English to Google Assistant and shaped tech for millions

When Google Assistant began responding more naturally to Nigerian accents and speech patterns, the change appeared subtle to many users. Yet behind that improvement was a broader effort to reshape how global technology platforms interact with emerging markets. One of the professionals who helped drive that transformation was Taslim Okunola, whose work as a Product Marketing Manager at Google focused on adapting global digital products for millions of users across Sub-Saharan Africa.

Localisation in technology often receives less attention than product innovation. Yet for companies seeking to scale globally, the ability of a product to understand language, cultural context and everyday user behaviour can determine whether it succeeds or struggles. Okunola’s work inside Google’s consumer applications portfolio illustrates how strategic localisation can influence technology adoption at scale.

“When people think about innovation, they usually focus on new features,” Okunola said in a conversation about his early work at Google. “But sometimes the most important innovation is making sure technology understands the people using it.”
At the time he joined the company’s regional team, Africa’s digital ecosystem was expanding rapidly. Smartphone penetration was rising, data costs were gradually declining, and millions of first-time internet users were coming online. Yet many global digital tools had been designed primarily for Western markets.
This created a practical challenge. Voice assistants often struggled with local accents and pronunciation patterns. Navigation platforms relied heavily on formal street addresses, which are not always the primary reference points for directions in many African cities. Even small design assumptions embedded in software interfaces could affect how easily new users interact with digital tools.

Okunola’s role was to help bridge that gap between global product design and local user realities.
One of the most visible outcomes of this effort was the introduction of Nigerian English voice recognition for Google Assistant. Voice-based technologies rely heavily on linguistic nuance, including accent patterns, vocabulary and sentence structure. Without localised training data and product insights, speech recognition systems can struggle to interpret commands accurately.

“If the system fails to understand a user consistently, trust breaks down quickly. Voice technology depends on familiarity. Once people feel the product understands them, adoption grows naturally,” Okunola explained.
Working alongside engineering and product teams, he helped provide the market insights and contextual understanding necessary to refine how Assistant interacted with Nigerian users. The goal was not simply technical accuracy, but also cultural authenticity.
The result was a more responsive and intuitive voice assistant for millions of people across the country.

Another key area where localisation proved essential was Google Maps. Navigation in many African cities often depends less on street names and more on landmarks such as bus stops, markets, churches or prominent businesses. In cities like Lagos, directions frequently reference these everyday markers rather than formal addresses.

Improving Maps for such environments required a deeper understanding of how people actually move through urban spaces.
“In Lagos, someone might say ‘turn after the bank’ or ‘opposite the market.’ If mapping technology cannot interpret that reality, it will never feel fully useful,” Okunola said.
By helping guide localisation strategies for Google’s consumer products in Sub-Saharan Africa, Okunola contributed to efforts aimed at making these tools more relevant and accessible for local users. Incorporating regional insights into global product development improved both usability and trust.
Beyond specific features, the experience also offered broader lessons about the economics of digital adoption in emerging markets.
Technology platforms scale most effectively when they reflect the everyday environments of their users. For global companies operating across diverse regions, this often requires balancing centralised product design with localised insight.

“A product becomes truly global only when it reflects the diversity of the people using it,” Okunola said.
Today, Okunola works in the United States as a Global Strategy and Operations Manager at Google, focusing on operational frameworks behind advanced AI products. Yet the lessons from his earlier work in Africa continue to shape how he thinks about technology strategy.
