What does SpeakKI do?

SpeakKI is an AI phone assistant built for appointment-based businesses. Instead of letting calls go to voicemail, it answers within a second, talks to callers in a natural-sounding voice, and handles everyday requests: opening hours, prices, callbacks, and booking appointments. The assistant is available around the clock, so a call at 2 a.m. on a Monday gets the same polite response as one during office hours.

You keep your existing phone number and forward calls to SpeakKI. Setup takes about 15 minutes: choose a greeting, set open time slots, and add answers to common questions. From there, the assistant can book directly into Google, Outlook, or Apple Calendar, check what's free, and avoid double bookings. It also sends SMS confirmations and 24-hour reminders, which the site says can cut no-shows by 40%. Callers hear a human-like voice, and the assistant can switch between 32 languages mid-conversation, handy if your customers speak Turkish, English, or Polish. After each call you get a summary with contact details and the reason for the call, via email or push notification.

SpeakKI is aimed at small and medium businesses that live by inbound calls: law firms, doctor's practices, physiotherapy clinics, tradespeople, and similar service providers. A tradesperson on-site doesn't have to interrupt work to answer the phone, and a practice doesn't need a reception desk after hours. Pricing starts at 39 euros per month, and there is a 50-minute free trial that doesn't require a credit card.
