Performance Evaluation of a Custom Voice Agent (Dasha Y186-custom-roy) for High-Latency Conversational AI in Customer Retention Scenarios

This paper presents the design, implementation, and evaluation of Dasha Y186-custom-roy , a domain-adapted conversational AI agent built on the Dasha platform. The agent was fine-tuned for customer retention calls in the telecom sector, with a custom prosody model (“Roy”) optimized for low-latency turn-taking and empathy detection. Dasha Y186-custom-roy

In A/B testing (n=500 calls), Y186-custom-roy reduced average call duration by 18% while increasing post-call customer satisfaction (CSAT) by 12% compared to the baseline Dasha generic voice agent. Latency was kept below 700ms P95. Performance Evaluation of a Custom Voice Agent (Dasha

We trained Y186 on 10,000 real conversation logs, integrating Dasha’s <vad> and <tts> tags with a custom interruption-handling logic. The “Roy” customization included pitch downshifts for reassurance phrases and speed modulation for urgency. Latency was kept below 700ms P95

Custom voice parameters significantly improve perceived agent rapport in retention contexts. Future work includes multilingual adaptation of the “Roy” voice profile.
