From payments and commerce to customer service, enterprises are discovering that India’s next AI user may not speak English at all
For years, India’s digital economy was built around an assumption that most technology users would eventually adapt to English-first interfaces. That assumption is now being challenged by artificial intelligence.
As AI moves from experimental deployments to mainstream customer experiences, some of India’s largest brands are discovering that language may be the most important adoption barrier standing between AI and its next billion users. The challenge is not simply translating content into Hindi, Tamil or Bengali. It is teaching AI systems to understand how Indians actually communicate through mixed languages, regional dialects, voice commands, colloquial phrases and cultural context.
The shift is already visible across sectors. Telecom giants, payment platforms, ecommerce companies, consumer goods brands and service providers are investing in multilingual AI systems designed specifically for Indian users. What began as a customer service initiative is rapidly evolving into a broader strategy involving search, commerce, payments, customer support, marketing and product discovery.
The numbers explain why.
According to the latest IAMAI-Kantar Internet in India report, the country had approximately 958 million active internet users in 2025. Rural India accounted for nearly 548 million users, representing more than half of the country’s active internet population. The same report found that 44% of internet users had already interacted with AI-enabled services, including voice assistants, AI-powered search, chatbots and image-based tools.
Another finding is even more significant for marketers. Nearly 98% of internet users consume content in Indic languages, while regional language preference continues to grow across urban markets as well. The result is a rapidly expanding audience that expects digital experiences in the language it is most comfortable with.
For brands, this creates a new challenge. AI models trained primarily on English internet data often struggle to understand the complexity of Indian language behaviour. A customer may search for a product in Hindi written in Roman script, switch to English midway through a sentence, and complete a transaction using a voice command delivered in a regional dialect.
Traditional localisation methods are no longer enough.
Language is becoming an AI infrastructure problem
Reliance Industries has been among the most vocal proponents of Indian-language AI. During the company’s 2026 annual general meeting, Chairman Mukesh Ambani said Reliance Intelligence is developing multilingual AI services across 22 Indian languages.
“Jio is building AI natively in Indian languages,” Ambani said while outlining the company’s vision for AI-powered consumer services.
The distinction is important. Earlier digital products were often built in English and later translated into local languages. AI systems, however, require language capabilities to be embedded into the core architecture. If a customer speaks a query in Marathi or mixes Hindi with English, the AI must understand intent, context and task completion simultaneously.
Reliance’s upcoming AI-powered call agent reflects this approach. The company says the service will be able to transcribe, summarize and process conversations in users’ preferred languages.
A similar strategy is visible at PhonePe.
Earlier this year, the fintech company introduced AI-powered natural language search capabilities that allow users to perform transactions using voice or text prompts. Instead of navigating through menus, users can simply describe what they want to do.
Rahul Chari, Co-founder and CTO of PhonePe, described the objective as making payments more accessible by allowing technology to understand user intent rather than specific commands.
The company has also expanded language support across its merchant ecosystem. Its SmartSpeaker devices now operate in 21 languages, serving millions of merchants across India.
The larger trend is becoming clear. AI is shifting from a translation layer to an interaction layer.
Ecommerce is rewriting search for a multilingual India
The ecommerce sector presents one of the clearest examples of why local-language AI matters.
India’s online shoppers are increasingly coming from Tier II, Tier III and rural markets, where English is often not the primary language of communication. Traditional keyword-based search systems struggle in such environments because users frequently describe products conversationally rather than using standard catalogue terminology.
Flipkart has been investing heavily in this area.
The company has integrated voice search capabilities across multiple Indian languages and dialects while simultaneously fine-tuning large language models for search, summarisation and recommendation engines.
According to Mayur Datar, Chief Data Scientist at Flipkart, the company’s AI initiatives are focused on making discovery more intuitive by understanding user preferences, budgets and intent rather than relying solely on keyword matching.
For ecommerce platforms, this represents a major opportunity.
India’s ecommerce market already serves hundreds of millions of consumers. Even small improvements in language accessibility can influence search success, product discovery and ultimately conversion rates.
The challenge, however, goes far beyond translation.
A shopper searching for a mixer grinder in Hindi may describe the product differently than someone searching in Tamil. Product attributes, regional preferences and local vocabulary all influence how recommendations need to be generated.
This is where AI training becomes business critical.
Where the training data comes from
The phrase “training AI” often creates the impression that companies are building large language models from scratch. In reality, most enterprises are taking a more practical approach.
Rather than developing foundation models independently, brands are combining public language datasets, proprietary customer data, conversation histories and industry-specific knowledge to adapt existing models for Indian use cases.
The growth of India’s language AI ecosystem has made this possible.
Project Vaani, a large-scale initiative involving research institutions and technology partners, has emerged as one of the country’s most significant language data projects. The initiative has already collected more than 31,000 hours of speech data from over 1.5 lakh speakers across 109 languages and dialects.
Its long-term goal is to create a dataset exceeding 150,000 hours of speech covering every district in India.
Another major contributor is AI4Bharat, whose language resources now include billions of Indic-language tokens and one of the world’s largest publicly available parallel translation datasets spanning multiple Indian languages.
These datasets provide a foundation for building speech recognition, translation and language understanding systems that better reflect how Indians actually communicate.
The scale of investment reflects growing industry demand.
Government-backed language platform Bhashini now supports more than 22 Indian languages and has partnered with dozens of public and private organizations. Meanwhile, BharatGen, India’s sovereign AI initiative, is focused on building models capable of understanding linguistic and cultural nuances across diverse Indian contexts.
Together, these initiatives are helping reduce one of the biggest obstacles facing enterprise AI adoption: the lack of high-quality local language training data.
Customer service is becoming the testing ground
If there is one area where multilingual AI is already producing measurable business outcomes, it is customer service.
Brands increasingly view customer support interactions as valuable training data for AI systems.
Every unresolved query, misunderstood request or failed conversation creates an opportunity for models to improve.
Bharat Petroleum’s AI assistant, Urja, provides a useful example. The multilingual system supports 13 languages and handles hundreds of customer interaction scenarios ranging from LPG bookings to service requests.
According to the company and its technology partners, nearly half of conversations handled by the platform now occur in non-English languages.
Asian Paints has reported similar results through its multilingual support systems. The company’s AI-powered customer service platform can interact in more than 50 languages and has helped reduce critical call volumes while improving response efficiency.
Sony India has also experimented with voice-based AI support, enabling customer service interactions in multiple languages while helping users identify service centres and resolve product issues through spoken conversations.
These deployments reveal an important reality about enterprise AI adoption.
Most companies are not attempting to create fully autonomous AI agents. Instead, they are focusing on narrow but high-value tasks where language understanding directly influences customer experience.
The objective is operational efficiency rather than technological spectacle.
The challenge of India’s mixed-language reality
One reason local-language AI remains difficult is that India is not a neatly segmented language market.
Consumers frequently switch between languages within the same sentence.
A user might type Hindi in Roman script, speak partly in English and complete a transaction using regional terminology.
This phenomenon, often referred to as code-mixing, has become one of the biggest technical challenges facing AI developers.
Hinglish remains the most visible example, but similar patterns exist across Tamil-English, Telugu-English, Bengali-English and several other language combinations.
AI providers serving enterprise customers are increasingly building systems specifically designed for such environments.
Instead of forcing users into a single language, newer models are being trained to understand mixed-language conversations and respond naturally.
This capability is becoming particularly important as voice interfaces gain popularity.
According to industry estimates, voice interactions continue to grow rapidly across rural and semi-urban markets where typing in local scripts remains less common than speaking.
For many users, conversational AI may become their primary gateway to digital services.
That makes language understanding a business necessity rather than a feature upgrade.
Why marketers are paying attention
The implications extend far beyond customer support.
For marketing teams, multilingual AI is increasingly influencing discovery, engagement, personalization and conversion.
As AI-powered search becomes more common, language quality will shape whether consumers can find products, complete transactions or receive relevant recommendations.
A customer who cannot effectively communicate with an AI assistant is unlikely to complete a purchase journey.
This is particularly relevant as brands move toward conversational commerce models where AI agents play a greater role in guiding users through decision-making processes.
Language capabilities also influence content creation.
Many organizations are now using AI tools to generate campaign assets, product descriptions, FAQs and customer communication across multiple languages. The ability to maintain consistency while adapting to regional nuances is becoming an important competitive differentiator.
At the same time, brands must balance scale with accuracy.
Industry experts continue to caution that language models can introduce translation errors, cultural misunderstandings and factual inaccuracies if not properly monitored.
That is why human oversight remains central to most enterprise deployments.
The goal is not to replace local expertise but to extend it.
The next phase of AI adoption may be regional
The conversation around AI in India often focuses on model sizes, funding announcements and technology partnerships. Yet for many enterprises, the more immediate challenge is ensuring that AI can function effectively in the environments where customers already live and communicate.
The next phase of AI growth is unlikely to be driven solely by English-speaking urban users. It will increasingly depend on whether systems can understand regional languages, dialects and everyday conversational behaviour.
India’s largest brands appear to have recognised that reality.
From Reliance and PhonePe to Flipkart, Bharat Petroleum and Asian Paints, companies are investing in language infrastructure that sits beneath customer experiences, payment journeys, search engines and support systems.
The objective is straightforward. AI cannot become mainstream in India if it only understands a fraction of how India speaks.
As enterprises continue to train models on local languages, customer conversations and regional behaviour, language itself is emerging as one of the most important battlegrounds in the country’s AI race.
For marketers, the lesson is equally clear. The future of AI adoption in India may not depend on teaching consumers how to use AI. It may depend on teaching AI how to understand consumers.
