DSP Agent

Key Features and Highlights

DSP Agent is an intelligent learning assistant workflow triggered by Telegram messages, specifically designed for students in the field of signal processing. It supports both text and voice inputs and leverages advanced language models such as OpenAI and Google Gemini for intelligent dialogue and instructional support. The workflow integrates multiple smart tools—including a calculator, Wikipedia queries, and memory storage—not only providing theoretical knowledge but also assisting with numerical computations and personalized learning tracking.

Core Problems Addressed

Signal processing concepts are often complex in traditional learning environments, making it difficult for students to quickly obtain targeted guidance and interactive tutoring. DSP Agent addresses these challenges by guiding students through intelligent conversations, helping them understand complicated concepts, offering dynamic problem analysis, and providing learning suggestions. It effectively resolves common pain points such as “not knowing how to ask questions,” “unable to solve problems,” and “lack of personalized tutoring.”

Application Scenarios

  • After-class tutoring for signal processing courses
  • Intelligent Q&A and knowledge acquisition during self-study
  • Extracting learning content via speech-to-text conversion
  • Personalized learning progress and memory management
  • Interactive exploration of complex problems by graduate students or engineers

Main Workflow Steps

  1. Telegram Trigger: Listens for text or voice messages sent by users via Telegram.
  2. Switch Routing: Determines the message type; text messages are processed directly, while voice messages first have their file IDs extracted.
  3. Telegram File Retrieval & OpenAI Transcription: Converts voice messages into text.
  4. Field Editing and Data Merging: Integrates text inputs with user memory data retrieved from Airtable.
  5. AI Agent Comprehension and Response: Utilizes multiple models (OpenAI GPT-4, Google Gemini) and tools (calculator, Wikipedia) for intelligent parsing, computation, and knowledge querying.
  6. Memory Update: Stores user interaction data in Airtable to support learning progress tracking and personalized recommendations.
  7. Feedback Output: Sends the intelligent assistant’s responses back to users via Telegram, completing the full interaction loop.

Involved Systems and Services

  • Telegram: Serves as the interaction gateway, supporting both text and voice communication.
  • OpenAI (GPT-4 model, audio transcription): Core engine for natural language understanding and generation.
  • Google Gemini Chat Model: Auxiliary language model to enhance dialogue quality.
  • Airtable: Stores user memory data to enable personalized learning tracking.
  • Wikipedia Tool: Provides authoritative knowledge query support.
  • Calculator Tool: Facilitates complex mathematical computations.
  • n8n Platform: Acts as the automation environment for executing the entire workflow.

Target Users and Value Proposition

  • Students and self-learners in signal processing and related fields seeking efficient, interactive tutoring.
  • Educational institutions and tutors looking to enhance teaching efficiency with supportive tools.
  • Researchers and engineers requiring rapid theoretical support and computational assistance during complex problem-solving.
  • Users who prefer obtaining professional knowledge and personalized learning advice through chat-based tools.

Summary
DSP Agent leverages Telegram as a convenient entry point and combines multiple AI models and auxiliary tools to create an intelligent signal processing learning assistant that integrates knowledge querying, speech-to-text conversion, computational support, and personalized memory management. It not only enhances the interactivity and depth of learning but also helps users systematically master complex technologies, significantly improving the overall learning experience and effectiveness.
