Our Doha conversational AI projects address the three layers that most vendors miss: dialect NLU, cultural design, and enterprise integration. Gulf Arabic NLU (weeks 1-3): building language understanding that actually works for Qatari users. Training data: we collect and annotate conversational data in Gulf Arabic — customer service transcripts, WhatsApp conversations (anonymised), and social media interactions from Qatari users. Gulf-specific vocabulary: "شلون" (shlawn — how), "وين" (wayn — where), "شنو" (shnu — what), "ليش" (laysh — why), "أبي/أبغي" (abi/abghi — I want), "مب" (mub — not), and hundreds of Gulf expressions not found in MSA training data. Intent classification: trained on domain-specific Gulf Arabic intents — not generic MSA. Banking intents: "أبي أعرف رصيدي" (abi a'arif rasidi — "I want to know my balance"), "شلون أحول فلوس؟" (shlawn ahawwil flus — "How do I transfer money?"), "متى يفتح البنك؟" (mata yiftah al-bank — "When does the bank open?"). Entity extraction: Gulf Arabic names (Qatari naming conventions: given name + father's name + family name — often without clear delimiters), Qatari phone numbers (starting with +974, 8-digit format), Qatar ID numbers (QID — 11-digit format), and Qatari addresses (area/zone/street/building number system — distinct from Western address formats). Code-switching handling: the model detecting language switches within a single message and processing each segment appropriately — "أبي أسوي appointment مع doctor حق العيون" ("I want to make an appointment with an eye doctor") parsed as: intent=book_appointment, speciality=ophthalmology, language=Gulf Arabic with English code-switching. Multilingual architecture (weeks 2-4): Doha's expatriate-majority population requires multilingual conversational AI. We implement: language detection (automatic identification of input language — Arabic, English, Hindi, Urdu, Filipino, French — routing to the appropriate language model), language-specific NLU (separate models per language, each trained on domain-specific data in that language), and consistent response quality across languages (the Hindi-language experience should be as good as the Arabic experience — not a degraded afterthought). For Hindi and Urdu (spoken by a combined 30%+ of Qatar's population): specialised NLU handling Hindi-Arabic mixing (Indian expatriates in Qatar frequently mix Hindi and Arabic — "bhai, kahan hai nearest ATM?" blending Hindi, Arabic-influenced vocabulary, and English). Cultural conversation design (weeks 2-4): Qatari conversational norms differ from Western patterns. Greetings: Arabic conversations begin with extended greetings — "السلام عليكم" (As-salamu alaykum) → response "وعليكم السلام ورحمة الله" (Wa alaykum as-salam wa rahmat Allah). Skipping or shortening greetings feels rude. Our chatbots: engaging in culturally appropriate greeting exchanges before proceeding to business. Formality: Qatari Arabic uses respect terminology — "أخوي" (akhuy — my brother) for male addressees, "أختي" (ukhti — my sister) for female. The chatbot: using appropriate respect terms based on detected or stated gender. Religious references: "إن شاء الله" (inshallah — God willing) used when discussing future actions — the chatbot naturally incorporating this when confirming appointments or promising follow-up. Privacy: Qatari users may be reluctant to share personal information with a bot. The chatbot: clearly explaining why information is needed and how it's protected, using reassuring language. Enterprise integration (weeks 3-6): conversational AI that only answers FAQs has limited value. We integrate with: CRM (Salesforce, Microsoft Dynamics — pulling customer history, updating records based on conversation), core banking (Temenos, Oracle FLEXCUBE — checking balances, processing transactions — with authentication and authorisation), government systems (visa status, application tracking — via government API where available, or structured data feeds), appointment scheduling (integrating with booking systems — checking availability, creating appointments, sending confirmations), and payment processing (enabling bill payment, recharge, and transfers within the conversation — with appropriate authentication). Channel deployment: deploying the same conversational AI across: WhatsApp Business (the dominant communication channel in Qatar — 85%+ daily usage), website chat (embedded on the organisation's website), mobile app (integrated into the native iOS/Android app), and voice (IVR — interactive voice response — with Arabic speech recognition for phone-based interactions). Human handoff: when the AI cannot handle a request (complex inquiries, emotional customers, VIP clients), seamless transfer to a human agent with full conversation context — the agent picking up where the AI left off without asking the customer to repeat information.
