Powering High-Volume Voice Agents at Scale | SigmaMind AI × Rime AI

High-volume call centers and enterprises face a tough challenge: how to engage customers in warm, human-like conversations at scale - while controlling operational costs. 

SigmaMind has resolved this with a partnership with Rime, whose text-to-speech (TTS) voices bring natural expressiveness, low latency, and emotional nuance to every conversation.

Built for Enterprise Scale

High call-volume enterprises and call centers need more than good voices. They also need infrastructure that doesn't falter under pressure. 

Together with Rime, SigmaMind delivers both: expressive, natural-sounding voices with the reliability and scalability enterprise operations demand.

The Partnership in Action

Our voice agents are tailored to varied call center needs - from empathetic customer support and precise lead qualification to friendly appointment reminders and compliant collections. 

SigmaMind’s multi-prompt, multi-turn conversation orchestration combined with Rime’s voice personas means agents sound more human, adapt naturally to caller moods, and provide relevant, context-aware replies.

The results speak volumes:

• Over 750k calls handled per month with Rime voices in production, delivering consistent quality.
• Cost efficiencies that improve margins by as high as 67%, thanks to Rime’s enterprise TTS pricing.

For enterprises scaling high-volume voice interactions, the SigmaMind AI and Rime AI partnership delivers what matters most: exceptional quality, proven reliability, and meaningful cost savings, without compromise.
