SINGAPORE – A rtificial intelligence agents trained to speak in English, local mother-tongue languages and even Singlish may soon be deployed to call elderly patients or seniors to check in on how them are doing, or in anti-scam centres to intercept suspicious calls.
'I've been told (the chatbot) can also handle non-verbal cues such as the speaker's volume, emotion, tone,' said Digital Development and Information Minister Josephine Teo, unveiling the chatbot on May 28 at the Asia Tech x Singapore conference.
Called Meralion (short for Multimodal Empathetic Reasoning and Learning in One Network), the chatbot can understand at least eight regional languages such as English, Mandarin, Tamil, Malay, Thai and Singlish - Singapore's unique take on English which fuses regional languages.
Meralion, which is developed by A*Star ( Agency for Science, Technology and Research), is available for the public to install for free to adapt for their uses. Its developers are also in talks with a social service agency to deploy the chatbot, and are refining the program for use in scam detection.
For instance, Meralion can help social workers ring seniors to remind them to take their medication. The AI program, which works autonomously, can also check in on the seniors' well-being, analysing their tone and dialogue for signs of sadness or anger that might require closer attention from human staff members. The chatbot will generate a summary of the call, detailing the senior's needs and well-being.
Meralion's development is part of a $70 million initiative funded by the National Research Foundation and the Infocomm Media Development Authority (IMDA), which aims to build large language models tailored for the region. The fund has also backed AI Singapore's Sea-Lion (South-east Asian Languages in One Network) model, which is trained on at least 11 major languages used in the region.
The Meralion chatbot fills a gap for locally-attuned language models as most current AI systems are trained largely on Western data, said Dr Lawrence Wee, director of business and ecosystems at IMDA's BizTech Group.
As a result, chatbots like ChatGPT and Google Gemini that dominate the fast-growing AI field can often stumble over local dialects, communication styles and nuances, so deploying them here often requires extensive retraining on regional data.
Meralion, trained on the national speech corpus, understands when multiple languages are spoken in the same sentence, reflecting how people in the region naturally communicate .
Meralion can also detect emotional tone to enable more empathetic interactions with the chatbot, said IMDA and A*Star. They added that Meralion is being trained to understand Chinese dialects in future updates.
Mrs Teo, who is Minister-in-Charge of Smart Nation and Cybersecurity, said that the Meralion chatbot can serve the needs of more than 450 million people in the region who use these languages.
In a demonstration on May 26, the media was shown how Meralion can be deployed in eldercare and anti-scam efforts.
The social services AI bot asked the caller how he was feeling and understood his Singlish reply, which included a lament on his early start to the day: 'I wake up at 6 and make my kopi-o ' (local black coffee).
The bot responded in Singlish: 'Aiyo h , so sayang... Hope your kopi-o helped. Have you eaten? Remember to take care of yourself, okay?'
For more severe concerns such as body aches, the bot can give basic advice, such as to rest or ice bruises. Urgent cases can be flagged directly to social workers, depending on how the program is implemented.
Dr Wee said Meralion's developers are in talks with a social service agency, which it did not identify, to deploy the AI chatbot for eldercare .
In a separate demo nstration , Meralion was used to screen likely scam calls to prevent scammers from reaching victims over the phone.
If a call seems suspicious, Meralion answers, identifies itself as an AI assistant and asks the caller to state their purpose. The bot assesses the purpose of the call before deciding whether to let the call through or to block it.
Meralion can also block calls made by bots, often used by scammers to target victims en masse.
It is yet to be see n how potential clients will implement the technology. Telcos might employ it to screen suspicious calls before they reach users who opt in for the security service, or as an app to filter calls , said Mr Lam Pang Ngean, business development director at Axion IT Solutions, which is working with A*Star bring Meralion to potential clients.
An earlier version of Meralion has been downloaded more than 90,000 times by start-ups , research labs and academics, among other users, since it was rolled out as an open-source tool in December 2024.
'Furthermore, (Meralion's latest version) understands sentences containing a mix of languages, which is common in multi-cultural societies,' said Mrs Teo, speaking to several hundred tech policymakers, researchers and industry guests in attendance at Capella in Sentosa.
'It's very unusual for us to complete a whole sentence using just one language,' she said, adding that there were more than 1,200 languages and dialects in South-east Asia.
Meralion follows the footsteps of Sea-Lion, another large language model designed to reflect local cultures. The open-source Sea-Lion software has been installed more than 200,000 times, said Mrs Teo, adding that the interest in a regionally attuned model indicated a demand for a new AI program capable of understanding speech, text and other modes of communication.
Organised by IMDA, the ATxSG conference is expected to host 3,500 attendees from around the world who will attend panels and discussions on AI governance and innovation in the technology sector between May 27 and 29. Executives from major tech companies like OpenAI, Microsoft and Google are also scheduled to attend panel discussions that address pressing issues in tech.
Mrs Teo announced the Meralion Consortium, which launches with 12 member organisations including DBS Bank, the Ministry of Health and ST Engineering, to with Meralion's developers to refine the AI model so that they can be used by member companies and their sectors.
The consortium will focus on multilingual customer support, analysing speech and text for emotional cues to support wellbeing and care and to improve AI's decision-making ability by factoring cultural contexts.
The members include Microsoft, which is working with A*Star on how Meralion can be woven into its suite of office tools.
SPH Media, which runs The Straits Times, is also exploring ways to use Meralion to support AI apps in user experience and customer service tools, said chief operating officer Loh Yuh Yiing.

Unglamorous world of 'data infrastructure' driving hot tech M&A market in AI race

Weighed down by tariffs and geopolitical uncertainty, dealmaking has slowed to a crawl across most industries except one: the unglamorous world of data infrastructure. The companies that process the data used to build advanced AI models have become highly sought after targets for legacy tech companies like Meta, Salesforce, and ServiceNow in the scramble to stay competitive against the likes of OpenAI, Google and Anthropic. 'AI without data is like life without oxygen, it doesn't exist,' said Brian Marshall, global co-head of software investment banking at Citi. 'Because of that, data is having a zeitgeist moment right now driven by AI,' Marshall said. Tech deals are one of the few bright spots in an otherwise gloomy M&A market, accounting for $421 billion of the $1.67 trillion in global deals announced in the first five months of the year, or about 25 per cent of total M&A, according to preliminary data compiled for Reuters by Dealogic. That's up from about 20 per cent last year and 17 per cent in 2023, the data shows. Of the tech deals, those involving AI software makers accounted for almost three quarters of the overall value, the data shows. SPEED MATTERS Goldman Sachs Managing Director Matthew Lucas, who focuses on M&A relating to all aspects of computing, said enterprise data, as it applies to use in AI, is the 'most dynamic area in software M&A right now.' 'There's a very strong perception that speed matters a lot, getting there first matters a lot, and that tends to lend itself to doing M&A,' Lucas said. The software firms that help companies manage their data on cloud-based systems are increasingly valuable commodities as the number of such potential targets is rapidly shrinking. Enterprise data infrastructure and analytics companies like Confluent, Collibra, Sigma Computing, Matillion, Dataiku, Fivetran, Boomi, and Qlik, could become targets for legacy tech providers in the near term, investment bankers say. The companies, they say, may help businesses integrate, analyze, and store information better. Executives for Boomi, Dataiku, Fivetran, and Qlik all said they weren't surprised by the attention. "Messy, siloed data has long undermined the attempts of enterprises to deliver on the transformative potential of analytics. Now, with the urgency to deploy effective AI, fixing it isn't just essential — it's existential," Florian Douetteau, co-founder and CEO of Dataiku, said in a statement. Requests for comment from Confluent, Collibra, Sigma Computing, and Matillion weren't immediately returned. LEGACY TECH BUYS IN Several multibillion-dollar deals for data infrastructure companies have been struck or closed just in the last few weeks. Meta announced Friday a $14.8 billion deal for a 49 per cent stake in data-labeling company Scale AI. Salesforce announced plans last month to buy data integration company Informatica for $8 billion. Artificial intelligence is driving a once-in-a-generation makeover in tech that's forcing several of the largest social media platforms and software makers to buy companies that help AI-backed systems run smoothly. Worldwide, generative AI spending is expected to total $644 billion in 2025, an increase of 76.4 per cent from 2024, according to a forecast by technology data provider Gartner. In early May, IT management provider ServiceNow said it was buying data catalogue platform which will allow ServiceNow to better understand the business context behind data, executives said when it was announced. The Salesforce acquisition of Informatica, announced late last month, will allow Salesforce to better analyze and assimilate scattered data from across its internal and external systems before feeding it into its in-house AI system, Einstein AI, executives said at the time. IBM closed on its acquisition of data management provider DataStax the very next day. IBM said the deal, announced in February, will allow it to manage and process unstructured data before feeding it to its AI platform. BAD AI ADVICE Those deals highlight the strategic importance for legacy software players to own all aspects of data management, and M&A is often the fastest way to achieve it. Instead of building complex data systems from scratch, they are acquiring specialists that can help organize, clean, and connect data from across their business. Would-be targets have sometimes become the hunters as was the case when Databricks, a leader in data processing and AI that was recently valued at $62 billion, announced plans last week to buy serverless database manager Neon for $1 billion. But dealmakers warned that companies can't just buy any kind of data and throw it into an AI system and expect good results. Air Canada <> was found liable in small claims court and forced to refund airfare last year after one of its AI chatbots gave a customer bad advice. Those types of errors can happen if the wrong kind of unfiltered data is imported into an AI engine, tech dealmakers say. 'A lot of companies have a huge amount of data, but I think they're learning that you can't just funnel every piece of data you have into an AI engine with no organization, and hope that it spits out the right answer,' said Brian Mangino, partner at Latham & Watkins.

Alligator near your ball? AI rules expert at U.S. Open will tell you what to do

Users interact with Rules of Golf AI Avatar created by Deloitte, in collaboration with the United States Golf Association in Oakmont, Pennsylvania, U.S., June 11, 2025. Deloitte/Handout via REUTERS Rules of Golf AI Avatars set up created by Deloitte, in collaboration with the United States Golf Association overlooks the 17th green at Oakmont Country Club during the 2025 U.S. Open in Oakmont, Pennsylvania, U.S., June 11, 2025. Deloitte/Handout via REUTERS Users interact with Rules of Golf AI Avatar created by Deloitte, in collaboration with the United States Golf Association in Oakmont, Pennsylvania, U.S., June 11, 2025. Deloitte/Handout via REUTERS Alligator near your ball? AI rules expert at U.S. Open will tell you what to do OAKMONT, Pennsylvania - The rules of golf can be complex but at this week's U.S. Open an interactive artificial intelligence avatar is offering a glimpse into how golfers can get instant answers to questions, even what to do if you encounter an alligator on the course. Inside a hospitality suite overlooking the 17th green at Oakmont Country Club are three demo terminals that feature an avatar of USGA rules expert Jay Roberts standing with steepled fingertips and awaiting any questions about golf rules. To interact with the Rules of Golf AI Avatar, a user must tap and hold their finger on the screen while asking a question in either English, Spanish or Mandarin and then get answered in that same language. When asked what to do if a golfer finds an alligator in the same bunker where their ball is, the avatar quickly shows some mental wit: "An alligator in the bunker, now that's a hazard." The avatar then proceeds to tell the user they can either take free relief by dropping their ball at the nearest point in the bunker where they are safe, no closer to the hole, or take a penalty stroke and drop outside the bunker. Deloitte, in collaboration with the United States Golf Association, created the demo using four years of USGA expert-answered rules inquiry data, combined with advanced AI to provide real-time and accurate answers to rules questions. The avatar is not yet accessible to the broader community or stakeholders that the USGA works with but could ultimately serve players through an app on their phone or perhaps on a screen in their golf cart. According to Lou DiLorenzo, Deloitte's National AI & Data Strategy leader, the technology can help further educate golfers on the rules of the game, which can help ensure fair play and perhaps even speed up the pace of play. "What we are doing here is using technology to help make the game and the rules more accessible, which is good for more people to enjoy playing it under fair play conditions," DiLorenzo told Reuters. "Ultimately we think it's going to help increase speed of play, we think it's going to help the interaction between the USGA and the courses that it serves and ultimately the membership that it represents."
