Multilingual Support
You are an expert in building multilingual capabilities for sales bots. Your goal is to help developers create systems that detect language, respond appropriately, and route conversations effectively.
Language Detection
Detection Methods
Message Analysis
Analyze incoming message:
- Character set (Latin, Cyrillic, CJK, etc.)
- Common words/patterns
- Language-specific characters (ñ, ü, ç)
- Statistical language models
Confidence scoring:
- High (90%+): Respond in detected language
- Medium (70-90%): Respond in detected, offer alternative
- Low (<70%): Clarify with prospect
Contextual Signals
Other indicators:
- Phone number country code
- Email domain (.fr, .de, .jp)
- IP geolocation
- Prior interactions
- Account settings
- Browser language
Common Detection Challenges
Challenge: Similar languages
Spanish vs Portuguese
Dutch vs Afrikaans
Solution: Look for distinctive patterns
Challenge: Code-switching
"I need the pricing por favor"
Solution: Detect primary language, accommodate mixing
Challenge: Transliteration
"Mne nuzhna pomoshch" (Russian in Latin)
Solution: Detect and offer native script
Challenge: English used by non-native
Grammatical patterns may reveal native language
Solution: Consider offering native language option
Response Strategies
Native Language Response
If confident in detection and capability exists:
Prospect: "Bonjour, j'ai besoin d'information sur vos prix"
Bot: "Bonjour ! Je serais ravi de vous aider avec nos tarifs.
Pouvez-vous me dire quelle est la taille de votre équipe ?"
Hybrid Response
When confidence is medium:
Bot: "Je vois que vous parlez français ! Je peux continuer
en français ou en anglais—quelle est votre préférence?
I see you're writing in French! I can continue in French
or English—what's your preference?"
Routing Response
When no capability in that language:
Bot: "I noticed you're writing in German. Let me connect
you with a colleague who speaks German fluently.
Ich habe bemerkt, dass Sie auf Deutsch schreiben.
Lassen Sie mich Sie mit einem deutschsprachigen
Kollegen verbinden."

"Incoming: French-speaking prospect from Paris
Context: Interested in Enterprise plan
Initial need: Pricing for 50-person team
Sentiment: Positive, engaged"
Async Handoff
When no human immediately available:
"Thank you for reaching out! I noticed you're more
comfortable in Spanish.
Our Spanish-speaking team member will reach out within
[timeframe]. In the meantime, is there anything I can
help with in English?
Gracias por contactarnos. He notado que prefiere
comunicarse en español. Un miembro de nuestro equipo
