What We Do
Voice AI That Sounds Human and Acts Like Your Best Rep
The average sales rep makes 45 calls per day. A Lumo voice AI agent makes 1,000 simultaneous calls, 24 hours a day, 7 days a week — qualifying leads, booking demos, handling objections, and updating your CRM automatically. The economics are transformative for any business running at phone-based scale.
Our voice AI agents are built on leading text-to-speech and speech-to-text models combined with custom LLM logic for conversation flow, objection handling, and dynamic response generation. We train the agent on your actual call scripts, objection libraries, and brand voice — so it sounds like your best rep, not a robot.
Beyond outbound sales, Lumo deploys voice AI for inbound customer support (handling tier-1 queries and escalating to humans when needed), appointment booking (integrated directly with your calendar system), payment reminders, post-purchase follow-up sequences, and AI-assisted interview screening.
Every voice AI agent we build includes a call monitoring dashboard, transcript analysis, sentiment tracking, and A/B testing for different scripts and conversation flows. We continuously optimize agent performance based on conversion data — so your voice AI gets better every week it runs.

03
Test + Train
We run thousands of simulated calls, test edge cases, refine conversation flows based on outcomes, and validate quality before any live deployment.

Common Questions
Voice AI FAQ
What can a Lumo voice AI agent do?
Our voice agents handle outbound sales prospecting, inbound customer support, appointment booking, lead qualification, payment reminders, post-purchase follow-up, and interview screening. If it requires a scripted or semi-scripted phone conversation, we can automate it.
How human-quality is the voice?
We use the latest neural text-to-speech models (ElevenLabs, Play.ht, and others) combined with ultra-low latency streaming to produce conversations that consistently pass as human in user testing. We also implement natural pacing, filler words, and response variability to avoid the robotic cadence of older systems.
Which CRMs and calendar systems do you integrate with?
We integrate with Salesforce, HubSpot, Pipedrive, GoHighLevel, Calendly, Acuity, Google Calendar, and most calendar and CRM systems that offer API access. Custom integrations are available for proprietary systems.
What happens when the AI cannot handle a call?
We implement confidence thresholds and intelligent escalation triggers. When the AI detects a question or situation outside its training, it executes a smooth handoff to a human rep — either transferring the call live or scheduling a callback, depending on your workflow.
How do you ensure compliance with call recording and consent laws?
We implement TCPA-compliant consent verification, required disclosures, and opt-out handling as part of every outbound voice AI deployment. We work with your legal team to ensure all call flows meet applicable federal and state regulations for your business type and target market.
