Voice AI is software that can hold a real-time phone or audio conversation. The current generation is genuinely conversational - it understands intent, follows context, and sounds natural enough that callers often don't realize they're not talking to a person.
What it does well
Answering and routing calls, qualifying leads, booking appointments, capturing intake details, handling FAQs, and taking simple support requests around the clock.
Where humans still win
Emotionally heavy conversations, complex troubleshooting, sales calls that require deep customization, and anything where accountability needs to sit clearly with a person.
How to deploy it well
Start with one well-scoped use case - usually after-hours coverage or overflow during peak times. Measure the calls handled, the appointments booked, and the customer feedback before expanding.
