Voice Analytics & AI-Powered Intelligence Platform
A real-time voice analytics solution that transforms verbal conversations into actionable business intelligence for sales teams, support centers, and executive decision-makers.
Trusted by Global Businesses
About Project
Our client needed a platform to capture live voice conversations, convert them to text instantly, and extract intelligence teams could act on. Existing tools fell short on multi-speaker accuracy and offered zero live coaching.
Business Goal
Build an enterprise-grade voice analytics platform with real-time transcription, automated speaker separation, AI-driven live coaching, and a comprehensive analytics dashboard, all within strict security and encryption standards.
Client Pain Points
- Manual sales call documentation
- Lack of engagement visibility
- Slow and inconsistent analysis
- Subjective performance evaluation
- No real-time coaching insights
Elevated the UI/UX
A clean, distraction-free dashboard that surfaces transcription streams, speaker labels, and live AI suggestions without clutter. Interactive timelines let users scrub conversations, review speaker segments, and access summaries in a single click.
Ai Powered Intelligence
The intelligence layer delivers real-time coaching suggestions during live calls, helping reps handle objections and close stronger. Post-session, the system auto-generates summaries with action items, key topics, and sentiment shifts across the full conversation.
Get Started
Key Challenges
Sub-Second Transcription Latency
Achieving near-instant speech-to-text across multiple speakers and accents required a custom WebSocket pipeline streaming audio directly to processing engines.
Reliable Speaker Diarization
Separating individual speakers in overlapping conversations needed an asynchronous layer combining multiple AI models for high-confidence identification.
Real-Time AI Coaching at Scale
Delivering live suggestions without lag demanded a lightweight inference layer running parallel to the transcription stream.
Enterprise-Grade Security
Sensitive conversations required end-to-end encryption, JWT authentication, role-based access, and parameterized queries across every data layer.
