The Language Barrier Problem
Your business is global. Your customers are everywhere. But your support team? They speak one or two languages.
The reality for most businesses:
- 72% of consumers prefer to buy in their native language
- 56% say native language content is more important than price
- Only 25% of internet users are English speakers
If someone messages you in Portuguese, German, Japanese, or Arabic—what happens?
Traditional Options (All Bad)
- Ignore them: Lose the sale/customer
- Respond in English: Frustrating for customer, low resolution rate
- Google Translate responses: Awkward, often incorrect, unprofessional
- Hire multilingual agents: Expensive, not 24/7, limited language coverage
Traditional Translation Solutions
Machine Translation Tools (Google Translate, DeepL)
- Pros: Fast, cheap
- Cons: No context, awkward phrasing, errors on industry terms
- Result: Customers know they're getting automated, low-quality responses
Outsourced Translation Services
- Pros: Higher quality
- Cons: Slow (hours/days), expensive, doesn't scale for real-time chat
Hiring Native Speakers
- Pros: Best quality
- Cons: $4,000+/month per language, limited hours, scaling nightmare
None of these work for real-time, 24/7 customer support.
How AI Multilingual Support Works
Modern LLMs (Large Language Models) don't just translate—they think in multiple languages. The difference is crucial.
Translation Approach (Old)
- Customer writes in Spanish
- Machine translates to English
- Agent (or AI) responds in English
- Machine translates response to Spanish
- Customer receives awkward, double-translated response
Native AI Approach (Wallu)
- Customer writes in Spanish
- AI understands intent directly in Spanish
- AI formulates response natively in Spanish
- Customer receives natural, fluent response
No double translation. No lost nuance. No awkward phrasing.
Wallu's Multilingual Capabilities
Automatic Language Detection
Wallu identifies the customer's language from their first message. No settings to configure, no customer input required.
Native-Quality Responses
Responses aren't "translated English"—they're generated natively in the target language. This includes:
- Proper grammar and syntax
- Cultural appropriateness (formality levels, honorifics)
- Industry terminology (trained on your specific vocabulary)
95+ Languages Supported

- Honorifics (formal/informal) for Japanese, Korean, German
Implementation Best Practices
1. Train on Multilingual Knowledge Base
Upload support documents in all target languages. If you have a Spanish FAQ, upload it. The AI will use it.
2. Define Language-Specific Responses
Some responses should differ by language:
- Shipping times to Germany vs Brazil
- Payment methods available in Japan vs USA
- Regional contact information
3. Set Escalation Languages
Configure which languages should escalate to humans (if you have native speakers available).
4. Test with Native Speakers
Before going live, have native speakers test the AI in their language. They'll catch cultural issues a non-speaker wouldn't notice.
5. Monitor Quality by Language
Track CSAT separately per language. If Japanese scores drop while others stay high—investigate.

Frequently Asked Questions
Can everyone on my team see translated conversations?
Yes. Wallu shows the original message AND an English translation side-by-side. Agents who don't speak the language can still supervise.
What about languages you don't fully support?
For less common languages, Wallu may have reduced fluency but will still attempt to help. For critical markets, we can prioritize training on specific languages.
Can I customize responses per language?
Absolutely. You can set language-specific FAQ answers, greetings, and escalation rules.
What about regional dialects?
Wallu handles major regional variations (Brazilian Portuguese vs European Portuguese, Latin American Spanish vs Castilian Spanish).
Is there additional cost for multilingual support?
No. All 95+ languages are included in every Wallu plan.
