This Langflow flow creates a comprehensive call transcription and classification system. The flow starts by taking an audio file and submitting it to AssemblyAI for transcription processing. It then monitors the transcription job until completion and retrieves the final transcript text.

Once the transcript is ready, the system processes it through a specialized AI agent designed for call analysis. The agent receives detailed instructions on how to classify calls based on topic, resolution status, sentiment, and urgency level. A parser component formats the transcript data appropriately before sending it to the agent for analysis.

The final stage uses structured output processing to ensure the results follow a consistent format. The agent's analysis gets converted into structured JSON data containing both the original transcript and classification details including topic, resolution, sentiment, and urgency fields. This structured output is then displayed through a chat interface, providing a complete call analytics solution from audio input to categorized results.

The flow can be extended significantly using other Langflow components. You can add vector store integration to match transcripts against knowledge bases for policy compliance checks, implement text splitting for processing longer calls, or connect to downstream systems like CRMs and data warehouses. Conditional routing can trigger escalation workflows for high-priority issues, while embedding models enable semantic search across historical call data. For production deployments, you can expose the entire flow as an API endpoint and monitor performance using LangSmith integration. Advanced implementations might incorporate MCP tools to call external services during analysis or chain multiple flows together for complex processing pipelines accessible through the flow API.
