What’s the difference between localisation and translation in AI?

Translation converts text from one language to another, while localisation adapts content, tone and cultural references so the AI feels natural to local users. Localised models account for slang, dialects and etiquette.

Do I need to build a model from scratch?

Not always. Many open-source models like SEA‑LION can be fine-tuned with local data. Starting from a base model saves time and resources while allowing you to tailor the system to specific languages.

How can I handle multiple dialects?

Collect data for each dialect and train or fine-tune models accordingly. Use separate tokenisers or embeddings if necessary, and test outputs with native speakers to ensure accuracy.

Localised AI Models for Southeast Asia: Development Guide

Localised language models like Bhashini, Sahabat-AI, ILMU and SEA-LION show that localising both language and cultural behaviours helps AI interact naturally with communities. Singapore’s SEA-LION supports more than 11 regional languages; Malaysia’s ILMU and Indonesia’s Sahabat-AI illustrate localised development. Building such models requires careful planning and community engagement.

Why Localisation Matters

General-purpose AI models trained on Western data struggle with Southeast Asian languages and cultural references. Localisation ensures that AI understands regional languages, slang and cultural norms, enabling natural interactions. Projects like Singapore’s SEA‑LION support more than 11 regional languages; Malaysia’s ILMU and India’s Bhashini show how national initiatives can build local-language models. Without localisation, AI risks misunderstanding users or producing inappropriate outputs.

Data-to-Deployment Framework

Develop localised models using five steps: 1. Define target languages, dialects and domains (e.g., Thai customer service or Bahasa legal chatbots). 2. Collect and annotate data from diverse sources, including local dialects, social media and industry-specific documents; collaborate with native speakers to ensure quality. 3. Fine-tune or train models using a base architecture like SEA-LION, focusing on tokenisation and script support for each language. 4. Evaluate with test sets covering dialects and cultural contexts; adjust for biases and errors. 5. Deploy and gather user feedback to continually refine the model.

Common Mistakes and How to Fix Them

Avoid assuming that Malay and Indonesian are interchangeable; dialect variations and script differences mean models must be tailored. Data scarcity is a major issue; create partnerships with universities and communities to gather data ethically and respect intellectual property. Do not ignore cultural values-tone, politeness and context vary widely across Southeast Asia. Finally, plan for multi-dialect support and continuous learning rather than one-time training.

Data Collection Plan

Plan a data collection campaign

As an AI product manager in Singapore, outline a plan to collect training data for a Vietnamese customer service chatbot. Include sources such as customer emails, social media posts and call transcripts, and specify how you will handle dialect differences and privacy.

Evaluation Guidelines

Create evaluation metrics

Draft a checklist for evaluating a multilingual AI model that serves users in Malaysia and Indonesia. Consider linguistic accuracy, cultural appropriateness and error handling for both Malay and Indonesian dialects.

Cultural Adaptation

Write a culturally sensitive user manual

Write a short user manual for an AI chatbot designed for Thai small business owners. Explain how the bot understands local expressions, encourages polite communication and uses examples relevant to Thai culture.

Pick one of these prompts and see where it takes you. The interesting bit is not just getting results - it is discovering what happens when you tweak the parameters or combine different approaches. If you end up with something unexpected (whether that is brilliantly unexpected or amusingly terrible), we would genuinely love to see it.

Share your results, your variations, or the weird tangents you went down trying to get things just right. That is often where the best insights come from: the collective trial and error of people actually using these tools in practice.

And if you found this useful, we have got plenty more practical how-to guides covering everything from creating images for your blog to helping you automate boring work tasks. Each one is built the same way: real techniques, actual examples, no fluff.
