I need an AI-powered calling workflow that will telephone 250 airports and 250 tourism boards spread across roughly 250 different states or regions worldwide. For each organisation the agent must confirm, on the call, the following: • the full name, direct phone number and email address of the Head of Marketing • the official name of their Advertising & PR agency (or agencies) I already hold many of the numbers, and I will add the rest to the dial list before we start. Every call has to sound natural—human-like, not robotic—and must be recorded end-to-end. I will later review both the MP3 files and the call logs, so clear labelling of each recording is essential. Because calls will span several continents, the voice bot needs to switch fluidly between at least twenty languages (English, Spanish, French, German, Mandarin, Arabic and the rest that the platform supports). If your stack can cover “all major languages,” even better. Accents should be region-appropriate to maximise answer rates. Deliverables I expect at hand-off: 1. A master spreadsheet (Excel or Google Sheets) containing the verified contact data for all 500 organisations, time-stamped and source-attributed. 2. A folder of call recordings, each file named with the organisation and date. 3. A brief daily progress summary so I can monitor completion against the 500-call target. I’m open to whichever tools—Dialogflow, Twilio Voice, Aircall, Microsoft Cognitive Services, etc.—get the job done, as long as voice quality is realistic and switching languages is seamless. Let me know how you will handle incorrect numbers, gatekeepers, and GDPR/consent compliance, and the approximate runtime per call so I can forecast timeline.

Hi, I have experience building AI voice automation systems with multilingual support and realistic conversational flows, and this project is very achievable with the right calling and transcription setup. I can help build a scalable workflow that handles multilingual outbound calls, captures and verifies contact details, records conversations, and organizes everything into structured reports with properly labeled recordings and daily progress tracking. Before starting, we should confirm the compliance requirements, expected call behavior with gatekeepers, and preferred approval flow for failed or uncertain responses.

Hi, As per my understanding: You want an AI-driven calling system to contact ~500 organizations globally, collect specific marketing contact details, record calls, support multi-language conversations, and deliver structured outputs with daily tracking. Implementation approach: I’ll design a compliant voice automation system using Twilio Voice + advanced TTS/ASR (e.g., Microsoft Azure Speech or ElevenLabs for natural voice). The workflow will include dynamic language detection and switching, with region-appropriate voices. A conversation engine (Dialogflow CX or custom LLM orchestration) will guide calls with human-like dialogue, handling gatekeepers, retries, and fallback to voicemail when needed. All calls will be recorded, labeled, and stored systematically. Data captured during calls will be structured into a central database and exported to a master spreadsheet with timestamps and source notes. I will implement logging, error handling for invalid numbers, and retry logic. GDPR compliance will be handled via consent prompts and clear identification of the caller purpose. A few quick questions: 1. Do you want fully automated calls or hybrid (AI + human fallback)? 2. Any priority regions/languages to start with? 3. Preferred cloud provider (Azure, AWS, etc.)? 4. Expected deadline for completing all 500 calls? 5. Do you require real-time dashboard monitoring in addition to daily reports?

Hi there! You are building an AI calling workflow for 500 global organisations and the real challenge is making multilingual voice agents sound human while reliably extracting verified marketing contact data across regions without losing accuracy. I recently built a multilingual outbound calling system using Twilio and Azure speech workflows where structured extraction and call recording improved data accuracy in large-scale outreach campaigns across multiple languages. I will use Twilio with Microsoft Azure Cognitive Services and Google Dialogflow to run natural conversations, switch languages dynamically, record each call in MP3 format, and store verified structured outputs in a clean spreadsheet. Check our work: https://www.freelancer.com/u/ayesha86664 How do you want the system to handle non-responsive gatekeepers, immediate retry, voicemail fallback, or alternate contact extraction path? I am ready to start — just say the word. Best Regards, Ayesha

Hi, I see you need an AI calling workflow to reach 500 organisations worldwide, capture marketing contacts and agency info, record calls in multiple languages, and deliver structured logs and recordings. The key is natural, human-like voice, multi-language support, and clear labelling. I’ve built similar automated voice systems using Twilio Voice and Microsoft Cognitive Services, handling multi-language calls, call recording, and dynamic data capture. In one project, the AI handled thousands of calls, switched languages on the fly, and exported verified contact info to Google Sheets while keeping recordings organised by contact and timestamp. For your workflow, I’d suggest using Twilio for call handling, OpenAI or Microsoft TTS for natural voice, and a scheduler that iterates through your list. Calls that hit gatekeepers or wrong numbers can be flagged automatically for review. Each call would log the timestamp, language, and organisation, with recordings named for easy reference. Daily progress summaries can be automated via Google Sheets or Slack. GDPR compliance can be built into the call flow with pre-recorded consent confirmation. I can build this workflow and estimate around 5–7 minutes per call including info capture. Would you like me to outline a 3-step language-routing and fallback plan for gatekeepers and wrong numbers? Best regards, Joel M.

Your need for a scalable, multilingual AI call system that handles 500 complex confirmations across diverse cultural contexts highlights operational challenges like natural tone, data integrity, and compliance. Achieving human-like dialogue that respects local accents and GDPR nuances while coordinating multi-continent schedules demands precision. I will configure a personalized AI pipeline using Twilio Voice integrated with Microsoft Cognitive Services for seamless language and accent adaptation. Calls will include dynamic scripting to navigate gatekeepers and prompt re-dial procedures for invalid numbers. Each call, averaging five minutes, will auto-label recordings and update a real-time Google Sheet with verified contacts and timestamps. Daily summaries will track progress and flag obstacles. Delivering verified, compliant contacts with flawless recordings within four weeks is the target. Which languages beyond the seven you mentioned carry priority for early testing and rollout?

Hi, This project requires more than basic calling or data entry. It involves an AI outbound calling workflow, multilingual voice support, call recording, data extraction, retry logic, spreadsheet reporting, and compliance-aware scripting. For the complete 500-organization workflow, my estimated budget is **$9,500 USD**. **Milestone 1 — Pilot Setup: $1,500** Set up the AI calling workflow, configure voice logic, test 25–50 calls, record calls, generate sample logs, and validate extraction accuracy. **Milestone 2 — Full Workflow Build: $3,500** Add handling for wrong numbers, voicemail, gatekeepers, callbacks, failed attempts, spreadsheet formatting, recording labels, and daily progress reports. **Milestone 3 — Production & QA: $4,500** Run the full 500-organization campaign, monitor results, review low-confidence data, clean the final spreadsheet, and deliver labelled recordings. This estimate assumes you provide the initial dial list and required consent/compliance wording. Telephony/API costs can be included with a capped allowance or billed separately. I recommend starting with the pilot first to confirm voice quality, language coverage, answer rate, and data accuracy before scaling.
