AI voice agents
never miss a call again
Our AI Voice Agents handle calls just like your best receptionist: friendly, accurate, and always available.
what is an
An AI Voice Agent speaks naturally with your callers — answering questions, booking appointments, routing calls, and collecting details just like a trained team member.
We design and develop these voice agents to sound natural, follow your process, and integrate with your systems — so your customers always get a consistent, high-quality experience.
Example use cases:
- Answering calls and routing them to the right person
- Booking or rescheduling appointments
- Handling common questions or service requests
- Capturing leads after-hours or during peak call volume

AI voice agent FAQ
- How much does an AI voice agent cost?
- Are there any additional costs beyond the initial build fee?
- AI processing (LLM usage): Each call uses processing power from the large language model (LLM) that makes your agent sound natural and intelligent.
- Phone number and call handling: Your AI Voice Agent connects through a dedicated business phone number. You’ll pay a small per-minute fee for that connection.
- Monthly maintenance and support: Big Fish provides ongoing monitoring, updates, and optimization to keep your AI Voice Agent accurate and reliable. This ensures that as your business evolves your voice agent receives updated training.
- How long does it take to build an AI Voice Agent?
The price to build a custom AI Voice Agent starts at $3,000.
At this level, your AI receptionist can answer calls, respond to common questions about your services, and transfer callers to a live person when needed.
If you’d like your Voice Agent to handle additional workflows – such as booking appointments, placing orders, or sending messages to your team – those features typically add $1,000 to $3,000 per workflow.
Most AI Voice Agent projects land between $3,000 and $10,000 total. The higher end covers more advanced agents that manage multiple flows, connect to external systems, or require deeper integrations.
When you consider how many hours of call-handling, scheduling, and repetitive Q&A that automation replaces, it’s worth asking: How long would it take your business to make back that investment in time and overhead saved?
Yes. In addition to the one-time build cost, there are ongoing operating costs for your AI Voice Agent.
Every live voice conversation your agent handles uses computing power (the “brain” behind it) and phone connectivity. These ongoing costs include:
Together, these recurring costs are usually modest compared to the time and payroll savings your business gains from automating routine calls.
Expect it to take 2 to 4 weeks from kick-off to launch.
Simple agents — those that answer FAQs and forward calls — can be ready in as little as two weeks. More complex builds that handle scheduling, integrations, or multiple workflows take closer to a month.
