AI Voice Agent
If your team is taking 30 minutes to call a Yelp or Thumbtack lead, you have already lost most of them. Auto-Respond's AI voice agent dials fresh leads inside 90 seconds, qualifies them, and books the appointment — usually before the prospect has even checked the next contractor's profile. Same-day deploy, pay only for the minutes you use.

What is an AI voice agent?
An AI voice agent is software that picks up the phone — and dials the phone — like a trained sales or service rep. It handles natural conversations: ums, interruptions, clarifying questions, the works. The pipeline runs three pieces in real time: speech-to-text, a reasoning model that consults your knowledge base, and natural text-to-speech, all stitched together with under 700ms round-trip latency.
For a service business, the voice agent does two jobs at once:
- Outbound. Calls every fresh Yelp, Thumbtack, Facebook, or Google LSA lead within seconds.
- Inbound. Answers your business phone 24/7.
How does it work?
On every call, four things happen in parallel:
- The prospect's audio is transcribed live.
- A reasoning model reads the transcript plus your knowledge base (services, pricing, hours, service area, FAQs) and decides the next response or action.
- The response is rendered to natural speech and streamed back.
- The agent writes to your CRM, books the calendar, sends confirmation SMS, and pings your phone with a job summary.
Outbound triggers automatically off lead events. A new Yelp Request a Quote arrives, a Thumbtack lead drops, a Facebook Lead Ads form submits — within 30-90 seconds the agent is dialing the prospect's phone.
Why speed kills (the conversation, in your favor)
Multiple studies — MIT, InsideSales, Harvard Business Review — converge on the same conclusion: contacting a lead inside 5 minutes lifts qualification rate 3-9x compared to contacting them after 30 minutes. After 24 hours, conversion is roughly halved.
Service business prospects on Yelp, Thumbtack, and Facebook are not patient. They are typing their problem on their phone right now and they are going to call whoever responds first. The AI voice agent is built for that exact moment.
AI voice agent vs human call center
Pricing comparison for 200 outbound calls per month, average 90 seconds each:
| Option | Pricing model | Monthly cost (200 calls) | Speed-to-first-dial | Books jobs? |
|---|---|---|---|---|
| In-house sales rep | Salary + commission | $3,500-$6,000 | 5-30 min (best case) | Yes |
| Offshore call center | Per-seat or per-hour | $800-$1,800 | 10-60 min | Limited (script only) |
| Pay-per-minute answering service | Per-minute, inbound only | $300-$600 | Inbound only | Sometimes (extra fee) |
| Auto-Respond AI voice agent | $10/mo number + $1/min | $310 | 30-90 seconds | Yes (real calendar integration) |
AI voice agent for outbound Yelp leads
Yelp Request a Quote leads come with phone numbers attached. Yelp's own data ties response speed to win rate roughly linearly. Auto-Respond dials inside 90 seconds, qualifies, and books — typically before the prospect has finished reading the next contractor's profile.
AI voice agent for outbound Thumbtack leads
Thumbtack charges per lead, often $40-80 in service categories. Slow follow-up burns lead spend. The AI voice agent dials the moment the lead drops. Cost-per-booked-job typically falls 30-50% in the first month after activation in our customer data.
AI voice agent for Facebook Lead Ads
Facebook Lead Ads produce volume — and the leads cool fastest of any channel because the prospect was scrolling, not actively shopping. Speed matters more here than anywhere else. The voice agent dials inside 60-90 seconds while the prospect still remembers filling out the form.
AI voice agent for Google LSA leads
Google Local Services Ads pass calls and messages directly. Google rewards advertisers with strong responsiveness and outcomes by ranking them higher in the LSA carousel. 24/7 AI coverage with consistent qualification directly improves both your booked-job rate and your LSA placement.
AI voice agent for inbound calls
The same agent that dials your fresh leads also answers your business phone. Sub-2-ring pickup, unlimited concurrency, 24/7. See the dedicated AI receptionist guide for the inbound side.
Batch calling and campaign dialer
Beyond per-lead dialing, the same voice agent runs campaigns. Upload a CSV (cold leads, dormant customers, expired estimates), set the script and qualifying questions, and the dialer works through the list at natural pacing. Common campaigns:
- Reactivate cold leads from the past 90 days
- Annual maintenance reminders
- Quote follow-ups for stalled deals
- Win-back outreach to lapsed customers
- Holiday or season-specific promotions
AI voice agent pricing
- $10/month per phone number
- $1/minute for actual call time
- No per-call fee, no per-seat fee, no minimum
- 7-day free trial with full voice agent access
Worked example: 30 Yelp leads/month plus 50 inbound calls, average 90 seconds each, runs ~120 minutes total — about $130/month all-in for two-way voice.

What to look for in the best AI voice agent
- Sub-1-second turn latency. Slower agents feel robotic and prospects hang up.
- Multi-platform lead-source integration. Yelp, Thumbtack, Facebook, Google LSA at minimum.
- Real outbound triggers. Not "we send you a Slack message" — actual auto-dial inside 90 seconds.
- Calendar booking with availability check. Booking blind produces double-bookings and angry customers.
- Recording, transcript, disposition. Every call should be reviewable.
- Live transfer with context. Warm handoff with summary, not a cold drop.
- Knowledge base grounding. Answers must reference your real services and pricing.
Frequently asked questions
What is an AI voice agent?
An AI voice agent is software that places phone calls and holds natural spoken conversations. It can dial outbound to fresh leads or answer inbound calls, qualify the prospect, and book appointments — all without a human operator.
How fast does the AI dial new Yelp and Thumbtack leads?
Within 30-90 seconds of the lead arriving in Auto-Respond. Most service businesses doing manual follow-up take 30-60 minutes — a gap that costs them roughly 60-80% of their potential conversions.
What is the difference between an AI voice agent and an AI receptionist?
An AI receptionist focuses on inbound calls. An AI voice agent does both directions — outbound to fresh leads in seconds, plus inbound coverage 24/7. On Auto-Respond, the same voice agent handles both on the same number.
Will the AI voice sound like a robot?
No. Auto-Respond uses enterprise-grade text-to-speech with sub-second turn latency. The voice handles interruptions, adjusts tone to context, and offers multiple voice options. Most prospects do not realize they are talking to AI.
How much does an AI voice agent cost?
$10/month per phone number, plus $1/minute for actual call time. No per-call fee, no per-seat fee, no contract. A typical service business spends $80-200/month all-in for two-way voice.
Can the AI voice agent run cold-call campaigns?
Yes. The batch dialer pulls a CSV or CRM segment, queues the calls, and works through the list at natural pacing. Common uses: reactivating cold leads, win-back, appointment reminders, follow-up on stalled estimates.
What if the AI cannot handle a specific call?
It live-transfers to your cell. You set the escalation rules — emergency keywords, high-value indicators, explicit caller request — and the transfer is warm with a quick spoken summary so you do not start cold.
Does the voice agent book directly into my calendar?
Yes. Real-time availability lookup against Google Calendar or Microsoft 365, with confirmed booking and SMS confirmation to the caller. For dispatch businesses it can also create a job in your CRM with full captured details.
Can I use my own business phone number?
Two options: port your existing number into Auto-Respond, or keep it where it is and forward to a new Auto-Respond number. Outbound calls can also display your existing number via caller ID.
How does the AI voice agent handle Spanish callers?
It auto-detects caller language and switches to Spanish without breaking context. English and Spanish are supported today.
Will the voice agent survive concurrent call spikes?
Yes. Capacity is effectively unlimited — the AI handles 1 call or 100 simultaneous calls with the same per-call quality. Heat waves, storms, and ad spikes do not produce busy signals.
How do I monitor performance?
Every call is recorded, transcribed, and dispositioned. The dashboard shows pickup rate, average call length, qualification accuracy, booking rate, and live-transfer rate. Listen to any call and tighten the persona based on what you hear.
