Open-Source Call Sentiment Tool Transforms Call Analytics
I Vibe codes tool to analyze call sentiment and topics from recordings
Customer service centers log thousands of calls daily. A programmer from KDnuggets wrote a tool that analyzes these recordings with open-source artificial intelligence. It transcribes the audio, measures sentiment, and finds common discussion topics, all on local hardware.
Every day, customer service centers record thousands of conversations. Hidden in those audio files are goldmines of information. Are customers satisfied?
What problems do they mention most often? How do emotions shift during a call? Manually analyzing these recordings is challenging.
However, with modern artificial intelligence, we can automatically transcribe calls, detect emotions, and extract recurring topics — all offline and with open-source tools.
The KDnuggets article explains the tool’s code, which uses libraries like Whisper for transcription. This approach turns archived calls into structured data a team can review, rather than raw audio it can’t easily search.

Common Questions Answered
How does the I Vibe Customer-Sentiment-analyzer process call recordings?
The tool uses Whisper, an automatic speech recognition (ASR) system, to transcribe call recordings. It then applies BERTopic for clustering and sentiment analysis, creating a lightweight pipeline that transforms raw phone logs into readable sentiment scores and topic clusters.
What are the initial setup steps for the Customer-Sentiment-analyzer project?
Users need to clone the GitHub repository, create a virtual environment, and activate it using Python. The project requires installing dependencies via pip install -r requirements.txt, with the first run downloading approximately 1.5GB of AI models for processing.
What technologies are integrated into the I Vibe sentiment analysis tool?
The project combines multiple technologies including Whisper for speech-to-text transcription, BERTopic for topic clustering, and Streamlit for creating a front-end interface. This allows developers to quickly set up a comprehensive call recording analysis solution without building each component from scratch.
