Voice AI development services Australia wide, and voice AI agent development for businesses in Perth, Melbourne, Sydney and Brisbane. The agent answers inbound calls, books appointments, triages enquiries and routes people, in ordinary spoken conversation.
Callers talk normally and the AI takes action. After-hours, overflow, or the front desk. Every call answered, every detail captured, and a fixed price before we start.
Built here. Your data stays here.
Five voice AI patterns we deploy most often across our ai voice assistant development work. Pick a tab to see how yours would take shape. Most businesses start with inbound or after-hours and add outbound campaigns later.
An AI voice agent that answers your phone line and handles inbound calls with natural spoken conversation. The caller speaks normally, "I need to book a plumber for Tuesday", and the AI understands, responds, and takes action.
It checks your calendar, confirms the appointment, sends a confirmation SMS, and logs the booking in your system. If the call needs a human, the AI transfers with a full summary so your team does not lose context.
An AI that takes over when your team goes home. After-hours calls are answered, enquiries are captured, bookings are made, and urgent calls are escalated to the on-call person. No more voicemail black holes.
The after-hours bot has all the same capabilities as during business hours, it checks availability, provides information, takes messages, and creates records. The caller does not know they are talking to an AI unless you want them to.
An AI voice agent that understands why someone is calling and routes them to the right person or team, without a phone tree. The caller describes their need in plain language and the AI figures out where to send them.
"I have a question about my invoice" goes to accounts. "I need to report a fault" goes to the service team. "I want to discuss a new project" goes to sales. Natural language routing instead of "press 1, press 2."
An AI voice agent that makes outbound calls on your behalf, appointment reminders, booking confirmations, follow-up calls, payment reminders, and survey calls. Consistent, tireless, and logged.
The AI calls the customer, delivers the message, and handles the response. "This is a reminder about your appointment tomorrow at 2pm. Would you like to confirm, reschedule, or cancel?" Natural conversation, not a recorded message.
An AI voice agent that triggers business workflows based on spoken interaction. A customer calls to report a fault, the AI logs the issue in your ticket system, notifies the assigned technician, and sends the customer a confirmation.
Works for any voice-to-action workflow: reporting incidents, placing orders, updating records, checking status, and triggering notifications. The caller speaks; the AI does the data entry and system updates.
We built an AI assistant trained on Medicare rules to answer billing and compliance queries in real time. Admin staff get accurate answers in seconds.
Read the full case studyWe were missing about 15 calls a day, mostly after hours and during lunch. The voice AI now handles those calls, books jobs directly into SimPRO, and sends the customer a confirmation SMS. First month: 40 extra bookings and zero voicemails.
Have a job like this one?
Every project is different, but the six-step structure stays the same. Call analysis, voice and knowledge setup, sprint-based build, testing with real callers, deploy and monitor, then optimise and expand once you are live.
We analyse your call patterns, volume, peak periods, common caller intents, current routing, and the calls your team struggles with. We map the ideal call flow for your voice AI.
We configure the voice AI, speech model, voice style, business knowledge, and system integrations. Connected to your calendar, CRM, helpdesk, or job management tool. Tuned for Australian English and your industry vocabulary.
We connect the voice AI to your phone system, VoIP, PBX, cloud-hosted, or mobile. No hardware changes. No number changes. Calls route through the AI before reaching your team, or only when your team is unavailable.
We test with realistic call scenarios, bookings, enquiries, complaints, edge cases, and escalations. Your team listens to test calls and we refine until the voice AI handles conversations to your standard.
Deploy to your live phone line. Real-time monitoring for the first week, we listen, review transcripts, and tune. Full analytics: call volume, resolution rate, escalation rate, and caller satisfaction.
We review call data, expand the voice AI to handle new call types, and optimise based on real usage. Add outbound calling, new integrations, or additional phone lines. Monthly performance reports.

| AU call recording + consent fit | Consent prompts + AU retention | US-hosted, no AU consent | Depends on your setup | Depends on the hire |
| Ongoing cost | Fixed price, one-time | Per seat/token, per month | Per-run + prompt engineering | Salary + super + overhead |
| When TTS/ASR models change | We patch, no extra charge | You rewrite the voice flow | You rebuild the flow | Internal team owns it |

A voice AI agent that answers your inbound phone number, understands what the caller wants in natural speech, books jobs, triages enquiries and routes calls. Deployed on your existing number via Twilio or similar. Trained on Australian accents and your specific business language. Every call is logged with a transcript.
Every project is scoped and quoted fixed-price. An inbound voice AI for a single call type, after-hours booking or FAQ triage, sits at the lower end. A larger deployment with multiple call flows, outbound calling and deep system integrations is more. Book a free 15-minute call, we scope the work, then quote once.
A focused voice AI for one call type takes 3 to 5 weeks. A larger deployment with multiple call flows, outbound calling and system integrations takes 6 to 10 weeks. We start with the highest-volume call type and expand from there once you see results.
Yes. The voice AI is tuned on Australian English speech patterns, regional accents, multicultural English and industry-specific vocabulary. We test it against your actual callers during the parallel-run phase and adjust before go-live.
The voice AI sounds natural, not robotic. Most callers do not realise unless told. We recommend transparency, a short line like "You are speaking with our AI assistant" at the start of the call. Callers accept it well when they get their issue resolved in under a minute.
Yes. When the call needs a person, the AI hands off with a spoken summary and a written transcript in your CRM or helpdesk. The caller does not repeat themselves. You control the transfer rules by topic, confidence level, caller request or time of day.
Yes. We connect the ai voice agent services to your existing business number. No number changes needed. Calls can route through the AI first, only when your team is unavailable, only after hours, or only for specific call types. Works with Twilio, Aircall, RingCentral, 3CX and most SIP providers.
Yes. Appointment reminders, booking confirmations, payment follow-ups and survey calls. The AI dials the customer, delivers the message in natural speech and handles the response conversationally. Every call is logged with the outcome for your team.
