Why Choose Lean Discovery Group?

We are a software development firm first, not a prompt shop. Every automation starts with mapping how the work actually gets done today, gets built on production-grade infrastructure, and ships with monitoring, documentation, and a team that maintains it. You own the code, the workflows, and the data, and we never take your IP.

What Is an AI Voice Agent?

An AI voice agent is a phone assistant powered by speech recognition, a large language model, and natural-sounding voice. It holds real conversations instead of pushing callers through a phone tree, and it can take actions like checking availability, booking appointments, or creating a ticket.

What AI Voice Agents Handle

Voice agents are best at the calls your team handles over and over, and at the calls that currently go to voicemail.

After-Hours Answering

Capture every call outside business hours with a real conversation instead of a voicemail most callers never leave.

Appointment Booking

Check live availability, book, reschedule, or cancel appointments, and send confirmations by text or email.

Inbound Lead Qualification

Ask your qualifying questions, capture details in your CRM, and warm-transfer hot leads to a salesperson.

Front Desk and FAQs

Answer questions about hours, pricing, services, and policies using your approved information.

Order and Status Lookups

Let callers check order status, application progress, or account details without waiting on hold.

Outbound Reminders and Follow-Ups

Confirm appointments, follow up on quotes, and collect simple information, within the calling rules for your industry.

How We Build Voice Agents People Do Not Hang Up On

  1. Script the real conversations. We study your actual calls to learn what callers ask and how your best staff respond.
  2. Choose voice and latency. We tune voice, speed, and interruption handling so the conversation feels natural.
  3. Connect your systems. Calendar, CRM, phone system, and knowledge base, so the agent can act and not just talk.
  4. Define the handoff. Clear rules for when to transfer to a person, with a summary passed along so callers never repeat themselves.
  5. Review and improve. Call recordings, transcripts, and outcomes are reviewed regularly to improve performance.

Platforms

We build on leading voice AI platforms and telephony providers such as Twilio, choosing the stack based on call volume, voice quality, latency, compliance needs, and cost. Your agent can work with your existing phone number.

FAQs

Do AI voice agents sound natural?

Today's voice AI sounds far more natural than older phone systems, with realistic voices and the ability to handle interruptions. We tune voice and pacing to fit your brand and test with real callers before launch.

Can the voice agent transfer calls to my team?

Yes. The agent can warm-transfer calls to a person or a department based on rules you set, and pass along a summary of the conversation.

Can I keep my existing phone number?

In most cases yes. We connect the voice agent to your existing number through forwarding or your phone provider, so callers see no change.

What does an AI voice agent cost to run?

Costs include a one-time build and ongoing per-minute usage from the voice and telephony providers. We estimate both during scoping based on your call volume.
