Sales teams often struggle with limited visibility into their calls, reviewing only 5-10% manually, which leads to missed opportunities. We built an AI-powered voice analytics tool that transcribes, indexes, and analyzes 100% of calls, turning them into actionable insights. In one case, this helped a SaaS client grow sales by 120% in 12 months.
What the tool does
We aimed to provide non-intrusive, automated QA at scale. So the key features include:
- 100% call transcription: using ASR for accurate, fast transcriptions.
- Searchable database: indexed transcripts for easy keyword and phrase tracking.
- Customizable reports: automated manager reports, grouped by agent or team.
- CRM integration: syncs data to tools like Salesforce and Zoho.
Limitations: currently lacks real-time alerts, sentiment analysis, and emotion scoring (planned for future updates).
Architecture overview
- Audio capture: integrated VoIP or manual uploads.
- ASR pipeline: transcribes calls via cloud-based speech-to-text.
- Transcript indexing: elasticSearch stores and retrieves data efficiently.
- Keyword matching: flags important terms like pricing or CTAs.
- Reports: automated generation of weekly summaries.
Real-world impact. One SaaS client improved
- 120% sales growth over 12 months.
- 35% increase in close rate by identifying high-performing patterns.
- 5-day reduction in sales cycle due to consistent messaging.
- Churn dropped from 15% to 6% through better objection handling.
This was achieved without expanding the team — simply by leveraging the power of data.
Challenges & lessons learned
- Keyword rules: over-flagging terms led to alert fatigue, so we customized per-client keyword sets.
- ASR model issues: addressed by adding pre-filtering for noisy inputs and fallback models.
- CRM integration: built middleware to adapt to varying CRM structures across clients.
- Manager overload: simplified reports to highlight top deviations, avoiding information overload.
Next steps: what's coming
- Trend detection: analyzing keyword frequency over time.
- Conversation templates: auto-tagging calls (intro, demo, pricing).
- Call quality scoring: identifying poor audio or incomplete conversations.
Key takeaways
- Focus on basics: transcription + search + simple flags bring massive value.
- Human-in-the-loop: insights are most useful when actionable in real-time.
- Scalability = simplicity: focused, simple solutions deliver better results.
- Data ≠ insight: reports need to be curated and actionable for managers.
Conclusion
AI is a powerful tool for sales teams, but success comes from turning raw data into actionable insights. By building scalable systems and avoiding complexity, we were able to achieve real business growth — and this approach is adaptable across industries.
Would love feedback from anyone working in voice AI, RevOps, or sales tooling.
