The Problem
What problem does this service solve?
Your phones ring and nobody answers. At peak hours, customers hear hold music or a busy signal and call a competitor. You can't hire enough staff to cover every call, and the ones who do answer aren't consistent.
The average restaurant loses around $292,000 a year to unanswered calls. A missed call isn't just a missed order - 69% of customers won't call back if nobody picks up the first time.
Overview
What is Voice AI development?
Every missed call is a customer who went somewhere else. We build voice agents that answer every call, handle the conversation, and push results straight into your systems - no hold music, no busy signals, no missed revenue.
Restaurants miss 43% of calls at peak. Clinics lose patients to voicemail. Sales teams let leads roll to hold music. A missed call isn't just one lost transaction - it's a customer who goes somewhere else and never comes back.
Voice AI that works in production isn't a chatbot with a microphone. It needs sub-second latency, real accent handling, interruption detection, background-noise filtering, and clean fallback to a human when confidence drops. Most demos skip all of this.
We build voice agents wired directly into your POS, CRM, and scheduling systems. Orders flow into the kitchen, appointments land on the calendar, and leads hit your pipeline without anyone typing them in.
Experience Signal
Built voice AI systems handling thousands of calls monthly - from phone ordering to appointment scheduling to behavioral research interviews. 12 weeks is our default, not our stretch goal.
What we build
Voice AI development services we deliver
Phone ordering voice agents
Voice agents that take phone orders, handle modifications and dietary questions, upsell on every call, and push orders straight to the kitchen display.
Appointment scheduling agents
Voice agents wired into your scheduling system that find open slots, book appointments, send confirmations, and handle rescheduling without a front-desk hop.
Inbound lead qualification agents
Voice agents that answer listing or product questions, qualify against your rubric, and book showings or demos for the leads that actually fit.
Outbound research and interview agents
AI voice agents that run structured interviews at scale, handle SMS retry logic, and deliver sentiment and keyword analysis without a human transcribing anything.
Customer service voice agents
First-line voice agents that resolve order lookups, returns, and account questions. Hand off to a human the moment confidence drops below threshold.
IVR replacement
Drop-in replacements for the multi-level menus customers hate. Natural conversation, no "press 2 for support," and real actions on the other end.
Healthcare intake agents
HIPAA-conscious voice agents for patient intake, symptom triage, and appointment booking across multi-location practices.
Voice analytics and QA
Sentiment analysis, keyword tracking, and call-level reporting so you can prove the ROI instead of guessing at it.
Fit
Is this service right for you?
Good fit
- Restaurant chains and QSRs handling high call volume for phone orders, catering, and reservations
- Healthcare clinics and dental groups running appointment scheduling across multiple locations
- Real estate firms that need 24/7 lead qualification on inbound calls
- Service businesses - HVAC, plumbing, legal intake - where a missed call is directly lost revenue
- Sales teams running outbound qualification or research interviews at volume
Not the right fit
- Businesses with fewer than 50 inbound calls per day (the economics may not work)
- Use cases that need full emotional support or crisis counseling
- Orgs unwilling to run human escalation paths for edge cases
Process
How does Voice AI development delivery work?
1
Phase 1· Week 1-2
Call flow design and voice architecture
We map your call scenarios, design the conversation flows, set escalation rules, and pick the right STT/LLM/TTS stack for your latency and accuracy targets.
Deliverables
- Call flow diagrams with branching logic and edge cases
- Voice architecture spec (STT, LLM, TTS selection with latency budget)
- Escalation rules and human handoff triggers
- Compliance and recording requirements
2
Phase 2· Week 2-5
Voice pipeline build and integration
We build the streaming voice pipeline, wire it into your POS, CRM, or scheduling system, and sync your menu or catalog live so the agent is never stale.
Deliverables
- Production voice pipeline with streaming STT/LLM/TTS
- POS or CRM integration with bidirectional data sync
- Knowledge base with business-specific vocabulary and constraints
- Interruption handling and endpointing configuration
3
Phase 3· Week 5-9
Testing, tuning, and accent calibration
We test with real calls across accents, noise conditions, and trolling attempts. We tune confidence thresholds, latency, and escalation against hard production benchmarks.
Deliverables
- Accuracy benchmarks across accent and noise profiles
- Latency waterfall with per-component breakdown
- Adversarial input testing (trolling, edge cases, off-menu requests)
- A/B comparison against manual call handling baseline
4
Phase 4· Week 9-12
Production rollout and monitoring
We deploy to production with live monitoring, stand up analytics dashboards, train your team on escalation, and set up a feedback loop for continuous improvement.
Deliverables
- Production deployment with telephony integration
- Real-time analytics dashboard (call volume, completion, accuracy, latency)
- Staff training on monitoring and escalation
- Post-launch optimization plan
Outcomes
- Every call answered instantly, 24/7, with zero hold time

Use Cases
Common use cases for Voice AI development
Phone ordering for restaurant chain
A pizza chain with 25 locations misses 40% of phone calls during dinner rush. That's roughly $15,000 per location per year in lost orders.
How we build it
We build a voice agent wired into their POS that takes phone orders, handles modifications and dietary questions, upsells on every call, and pushes orders straight to the kitchen display.
Outcome
100% call answer rate. 99% order accuracy. $893,000+ in phone order revenue recaptured. Staff freed from phones to serve in-store guests.
Appointment scheduling for dental group
A dental group with 30 locations handles 500+ daily calls for scheduling, rescheduling, and insurance questions. Hold times hit 4 minutes and 30% of calls get abandoned.
How we build it
We build a voice agent that reads the scheduling system, finds open slots, books appointments, sends confirmations, and handles rescheduling - with automatic escalation for insurance questions.
Outcome
Zero abandoned calls. Scheduling time drops from 4 minutes to 90 seconds. Front-desk staff shift back to patient care.
Inbound lead qualification for real estate
A real estate firm gets 200+ inquiry calls a week. Agents burn 60% of their time on unqualified leads asking basic questions about listings.
How we build it
We build a voice agent that answers listing questions from the property database, qualifies leads against budget, timeline, and location, and books showings for the ones that fit.
Outcome
Agents spend 80% of their time on qualified leads. Lead-to-showing conversion climbs 35%. 24/7 availability captures after-hours inquiries that used to die at voicemail.
What clients say
Real feedback from real teams
We went from text surveys that nobody finished to AI phone interviews that people actually enjoy. The voice agents handle the whole conversation, and the analytics tell us what we need to know without reading a single transcript.
