Voice RAG Chatbot z ElevenLabs i OpenAI w n8n

Ten szablon automatyzacji w n8n tworzy interaktywnego głosowego chatbota, który wykorzystuje zarówno tekst, jak i głos do dostarczania informacji. Idealny dla sklepów, działalności komercyjnych i restauracji.

Jak to działa

Oto szczegółowy opis działania workflow:

  • Aktywacja webhooka: Proces rozpoczyna się, gdy użytkownik wchodzi w interakcję z agentem głosowym w ElevenLabs, uruchamiając webhook w n8n.
  • Przetwarzanie przez AI Agent: Węzeł AI Agent przetwarza zapytanie używając wstępnie zdefiniowanych promptów i narzędzi.
  • Pobieranie z bazy wiedzy: Węzeł Vector Store Tool łączy się z bazą Qdrant, aby pobrać odpowiednie dokumenty pasujące do zapytania.
  • Generowanie odpowiedzi: Model OpenAI Chat generuje spójną odpowiedź na podstawie pobranych informacji.
  • Dostarczenie odpowiedzi: Wygenerowana odpowiedź jest przesyłana z powrotem do ElevenLabs, gdzie jest konwertowana na mowę.
  • Ciągła interakcja: Window Buffer Memory przechowuje historię rozmów, zapewniając płynność konwersacji.

Kroki konfiguracji

Aby poprawnie skonfigurować ten workflow, wykonaj następujące kroki:

  • Utwórz agenta w ElevenLabs i dostosuj pierwszy komunikat oraz prompt systemowy.
  • Dodaj narzędzie Webhook oznaczone etykietą do odbierania pytań.
  • Zainicjuj kolekcję w Qdrant używając węzłów HTTP Request.
  • Pobierz dokumenty z Google Drive, wygeneruj embeddingi i przechowuj je w Qdrant.
  • Skonfiguruj węzeł AI Agent z odpowiednim promptem systemowym i narzędziami.
  • Przetestuj cały workflow, monitorując logi i wyniki.
  • Zintegruj widget chatbota na swojej stronie internetowej.

Przykłady zastosowań

Ten zaawansowany chatbot głosowy może być wykorzystany w wielu scenariuszach biznesowych. Oto kilka potencjalnych zastosowań:

  • Obsługa klienta w restauracjach - odpowiadanie na pytania dotyczące menu i składników
