Summary (for PPH): Build a German voice agent for property management (Hausverwaltung) that answers calls, understands intent (incl. emergencies), creates/updates tickets, forwards to on‑call staff, schedules visits, and sends email/SMS updates. Orchestrate in n8n, use ElevenLabs for real‑time voice, and integrate Google (Gmail, Calendar, Drive, Sheets). Include GDPR consent/retention, low latency, and clear handover docs. Deliver milestone‑based with acceptance tests.
Project Description: AI Voice Agent for Property Management (n8n + ElevenLabs)
We need a production‑ready German voice agent built in n8n with ElevenLabs real‑time voice. It must answer calls, classify intent (emergency, maintenance, admin, status), create/update tickets, warm‑transfer to the right person, schedule site visits, and send email/SMS updates. Targets: 95% of calls answered within three rings, >90% intent accuracy, first reply ≤1.5 s, and after‑hours emergencies reaching the on‑call contact in ~60 s. GDPR must be met (recording consent, data minimization, configurable retention, least‑privilege access).
Stack: telephony (Twilio or similar) streaming audio into n8n; low‑latency German STT with an EU data path; LLM tool/function calls; ElevenLabs TTS. MVP ticketing can use Google Sheets with a compact schema and deduplication by phone + address. Include voicemail transcription, a short “whisper” on transfer, a small Drive‑based knowledge base, and basic analytics in Sheets/Looker (volume, intents, handle time, escalations).
Integrations: Gmail for confirmations/alerts, Calendar for on‑call and appointments, Drive for transcripts/media, Sheets for tickets/analytics, optional Contacts/CRM. Add a media‑upload link that stores files in Drive and attaches them to the ticket. Provide German by default (English optional), spam defenses, DTMF fallback, and auto‑failover to human/voicemail during outages.
Deliverables: deployed test and production numbers; exported n8n workflow JSON and environment variable list; telephony configuration; prompt pack with tool specs; JSON schemas and sample Sheets; a runbook for setup/operations/rollback; a test plan with results; and a recorded handover (≈60 minutes). Milestones: M1 design + hello‑world; M2 MVP flows (emergencies, tickets, Gmail/Sheets, analytics); M3 escalation and scheduling; M4 status checks, media upload, knowledge base, security, documentation.
In your bid, specify the chosen telephony, STT, and LLM with latency data and EU handling, links to similar work, pricing (fixed or hourly with caps), and estimated monthly run costs (telephony/min, LLM, ElevenLabs, n8n). We will provide access to n8n, ElevenLabs, the telephony account, and a scoped Google Workspace. Prioritize n8n orchestration, low latency, configuration in Sheets, and two German voices for A/B tests.
