Project Overview
Natvoiz is an end-to-end AI Voice Bot Platform capable of handling enterprise-scale voice interactions across recruitment, insurance, sales, and customer support use cases. Built for Natsoft, a US-based consulting enterprise with over 2,000 employees.
💡Replace repetitive, high-volume human calling workflows with AI-driven, human-like voice conversations.
The Client: Natsoft
Natsoft is a US-based consulting enterprise with over 2,000 employees and BPO operations. They faced major operational issues in their recruitment workflow - high recruiter workload, candidate drop-offs, and no structured way to capture feedback.
💡From recruitment automation to a full enterprise voice platform.
The Problem
High recruiter workload due to repetitive follow-ups. High candidate drop-off after offer rollout. No structured way to capture why candidates reject offers. Manual follow-ups leading to delays, inconsistent data, and recruiter burnout.
💡They needed an AI system that could screen candidates, follow up automatically, and share structured insights back to their CRM.
Platform Vision
Instead of building a single-purpose bot, we proposed and built a platform a configurable AI voice orchestration system that non-technical users can adapt to multiple business workflows without engineering support.
💡This decision later enabled rapid expansion into insurance, sales, and customer support use cases.
Visual Flow Builder
A user-friendly drag-and-drop flow builder where users can create conversation nodes, define prompts and responses, connect logic paths visually, configure fallback scenarios, and design complex multi-step call flows.
💡Usable by HR, Ops, and Business teams not just engineers.
AI & Voice Stack
Fully configurable speech-to-text, LLM, and text-to-speech providers for each flow.
Speech-to-Text
Deepgram, Google STT, AssemblyAI, Gladia
LLM Providers
OpenAI GPT models, Google LLMs for reasoning
Text-to-Speech
ElevenLabs, Google TTS with configurable voice/tone
Intent Detection
Real-time sentiment analysis and intent recognition
RAG Support
