Real-Time AI Voice Agent for Cold Calling
We developed a real-time voice-to-voice AI agent for the client, one of the top affiliate CPA networks. It delivers human-like conversations, handles noisy environments, and integrates with the client’s CRM and ATS. Trained on sales data, it boosts performance with <450 ms response time and a 1:1–1.5 sales quality ratio vs. human agents.
Challenge
* Build a real-time, natural-sounding voice-to-voice AI agent as close as possible to human speech. * Train the AI voice bot on sales techniques and product knowledge. * Ensure voice recognition in noisy environments during real-time calls. * Seamlessly integrate with the client’s custom CRM and ATS systems
Solution
* We selected a voice model with human-like sound quality and developed an AI agent optimized for real-time, natural conversations. The AI voice was fine-tuned to be expressive and lifelike, ensuring more natural interactions. * Using data from hundreds of hours of sales calls, scripts, and marketing materials, we built a custom database via Retrieval-Augmented Generation (RAG). Leveraging a fine-tuned LLM and the LangChain framework, we developed a reliable AI capable of handling real-world sales conversations, objection handling, and upselling scenarios. * We developed a custom noise suppression framework using adaptive models, allowing the AI to accurately recognize and process speech even during calls with background noise. This ensures clear voice recognition and natural conversation flow, even in suboptimal acoustic conditions. * We integrated the voice agent with the client’s CRM and ATS, enabling real-time call logging, automated data synchronization, and streamlined workflows across platforms.
Results
The client aimed to gain a competitive edge by embedding AI into their workflows, enhancing efficiency and improving customer interactions. We built a custom AI voice agent capable of real-time, two-way voice interaction with human-level responsiveness. With sub-450 ms latency and operating costs under $4/hour, it delivers scalable, natural conversations. Matching or exceeding human performance with a 1:1–1.5 sales quality ratio, the solution enables scalable outreach, reduces cost per interaction, and ensures consistent conversion results. It enhances operational efficiency and unlocks new revenue streams, turning AI into a strategic asset.
