HR & IT Helpdesk Chatbot with Audio Transcription
Go to Workflow
Felipe Braga
Description
An intelligent chatbot that assists employees by answering common HR or IT questions, supporting both text and audio messages. This unique feature ensures employees can conveniently ask questions via voice messages, which are transcribed and processed just like text queries.
How It Works
Message Capture: When an employee sends a message to the chatbot in WhatsApp or Telegram (text or audio), the chatbot captures the input.
Audio Transcription: For audio messages, the chatbot transcribes the content into text using an AI-powered transcription service (e.g., Whisper, Google Cloud Speech-to-Text).
Query Processing:
The transcribed text (or directly entered text) is sent to an AI service (e.g., OpenAI) to generate embeddings.
These embeddings are used to search a vector database (e.g., Supabase or Qdrant) containing the company’s internal HR and IT documentation.
The most relevant data is retrieved and sent back to the AI service to compose a concise and helpful response.
Response Delivery: The chatbot sends the final response back to the employee, whether the input was text or audio.
