Analyze Call Recordings with OpenAI and Update Zoho CRM Leads Automatically

Zoho CRM - Conversation Intelligence Analyzer

This workflow automatically processes customer call recordings, transcribes them using OpenAI Whisper, extracts key topics, identifies commitments, analyzes sentiment, generates follow-up suggestions and updates the corresponding Zoho CRM Lead — all without manual efforts.

It eliminates the need for listening to calls or writing summaries and equips your sales team with instant AI-generated insights.

⚡ Quick Start (Fast Setup)

Import the workflow JSON into n8n. Add Zoho CRM OAuth2 & OpenAI API credentials. Copy the webhook URL and configure your telephony system to POST call recordings. Map Zoho custom fields. Upload a test recording → Confirm CRM updates → Activate workflow.

📘 What It Does

This workflow turns every incoming call recording into structured insights which your sales & customer support team can immediately use. When a recording is received, the call is automatically transcribed using OpenAI’s Whisper model. That transcript is then processed by multiple AI nodes that detect topics, customer sentiment, commitments and possible follow-up actions.

All extracted data — such as mood, sentiment score, subjects, action items and commitments is merged into a clean result object and pushed to the matching Lead in Zoho CRM. The sales team gets ready-to-use call intelligence instantly, improving decision-making, accuracy and speed.

This automation works 24/7 and replaces hours of manual review work with reliable AI-generated summaries.

👤 Who’s It For

Sales & Customer support teams using Zoho CRM. Support teams handling inbound/outbound calls. Businesses wanting call analytics without manual transcription. Zoho CRM admins who want automation with minimal maintenance. Organizations using telephony/VoIP systems that support call exports.
