Voice AI & Phone FAQs
Common questions about automated call handling, AI receptionists, and voice-to-action technology.
Voice AI is technology that uses natural language processing (NLP) and speech recognition to understand and respond to human speech over the phone. ShadowBook's Voice AI engine acts as a virtual agent that can handle complex conversations, book appointments, and process orders just like a human receptionist but with infinite scalability.
To set up Voice AI with ShadowBook, you simply connect your business phone number (via Twilio or SIP). You then define your business logic, sync your calendar or product catalog, and the AI will begin answering inbound calls or placing outbound follow-ups automatically, complete with native payment processing.
In 2026, the best Voice AI tools are those that offer low-latency, human-like interaction and direct backend integration. ShadowBook is a top-rated choice because it doesn't just 'talk'—it executes actions like checking real-time inventory or updating your Property Management System during the call.
Businesses use Voice AI assistants to ensure every call is answered instantly, reducing lead leakage and operational costs. It allows human staff to focus on high-value tasks while the AI handles routine inquiries, scheduling, and basic transactions 24/7.
ShadowBook is uniquely positioned as the best Voice AI for booking because it features deep integration with Google Calendar, Outlook, Mews, and Apaleo. This allows the AI to negotiate available slots with the caller and confirm the booking in real-time.
