Setting Up a Bangla-Language Hermes Agent Bangladesh for Your Business

One of the most frequently asked questions about Hermes Agent Bangladesh is whether it works in Bangla. The answer is yes — the Gemma models powering Hermes have strong Bangla language support. This guide shows you how to configure your agent to respond in Bangla, handle mixed Bangla-English conversations, and load Bangla content into the knowledge base.

How Hermes Handles Bangla

Hermes uses Google DeepMind's Gemma models, which are trained on multilingual data including Bangla (Bengali). The models can:

• Read and understand messages written in Bangla script
• Generate responses in Bangla script
• Handle mixed Bangla-English inputs (common in Bangladesh messaging)
• Understand transliterated Bangla (Banglish — Bengali words written in English letters)

Bangla quality is strongest for general conversation, customer service, and FAQ-style queries. Technical and highly specialized topics have stronger English performance, which is standard across LLMs.

Step 1: Configure the System Prompt for Bangla

The system prompt tells Hermes how to behave. For a Bangla-primary agent, set it like this:

আপনি [ব্যবসার নাম]-এর একজন সহায়ক কাস্টমার সার্ভিস প্রতিনিধি।
আপনি সর্বদা বাংলায় উত্তর দেবেন, তবে গ্রাহক যদি ইংরেজিতে লেখেন,
তাহলে ইংরেজিতেও উত্তর দিতে পারবেন।
আপনি বিনয়ী, সংক্ষিপ্ত এবং সহায়ক।
আপনার কাছে [ব্যবসার নাম]-এর পণ্য তালিকা, মূল্য তালিকা এবং ডেলিভারি নীতি সম্পর্কে তথ্য আছে।

Translation: "You are a helpful customer service representative for [Business Name]. You always reply in Bangla, but if the customer writes in English, you can reply in English too. You are polite, concise, and helpful. You have information about [Business Name]'s product catalog, price list, and delivery policy."

For a bilingual agent that automatically matches the customer's language:

You are a customer service assistant for [Business Name], a business in Bangladesh.
Detect the language of each incoming message and reply in the same language.
If the message is in Bangla or Banglish, reply in Bangla.
If in English, reply in English. Be polite, concise, and accurate.

Step 2: Prepare Your Knowledge Base in Bangla

If your customers write in Bangla, your knowledge base should also include Bangla content so Hermes can give accurate answers. Prepare documents that include:

• Product names and descriptions in Bangla
• FAQ answers in both Bangla and English
• Delivery area and pricing information in Bangla
• Return and exchange policy in Bangla

You can upload plain text, PDF, or Word documents to the Hermes knowledge base. Qdrant handles vector storage for both Bangla and English content — retrieval works across languages because the embedding models are multilingual.

Step 3: Test Bangla Conversations

Before going live, test your Bangla configuration with realistic customer messages. Common test cases for a Bangladesh retail business:

• "এই পণ্যটির দাম কত?" (How much does this product cost?)
• "আপনারা কি ঢাকার বাইরে ডেলিভারি দেন?" (Do you deliver outside Dhaka?)
• "আমার অর্ডার কখন পাব?" (When will I get my order?)
• "রিটার্ন পলিসি কী?" (What is the return policy?)
• "ki price?" (Banglish — "what is the price?" mixed language)

Check that responses are natural-sounding in Bangla and that facts from your knowledge base are retrieved correctly.

Common Issues and Fixes

Agent replies in English even when asked in Bangla

The system prompt language instruction may not be strong enough. Add this phrase to your system prompt: "ব্যবহারকারী বাংলায় লিখলে সর্বদা বাংলায় উত্তর দিন।" (Always reply in Bangla when the user writes in Bangla.)

Agent gives wrong product names in Bangla

Your knowledge base may have product names only in English. Add Bangla spellings/names of your products alongside the English versions so the agent can match what customers type.

Banglish inputs not understood

Add example Banglish versions of common queries to your knowledge base FAQ — e.g. "dam koto?" alongside "দাম কত?" and "How much?" for the same question. This helps the retrieval layer find the right content regardless of how the customer writes.
