AI-Powered Sales Training with Voice-Based LLM Conversations

Challenges We Resolved

Lack of Realistic Sales Training Tools: Traditional training methods were limited to static scripts and role-play exercises, leaving agents unprepared for dynamic customer conversations.
Insecure & Fragmented User Management: Existing systems lacked enterprise-grade security, offering no robust authentication, password recovery, or profile management.
Manual Persona Management: Trainers had difficulty creating, editing, and managing customer profiles, restricting flexibility in training scenarios.
Scalability & Reliability Gaps: Without proper cloud infrastructure, the system could not ensure high availability, performance monitoring, or automated backups.

The client required a secure, scalable AI-powered platform capable of simulating real-world conversations and providing actionable feedback to sales agents.
