Voice AI is a technology that allows machines to understand and respond using natural voices — from IVR keystrokes to modern voicebots — helping the switchboard operate 24/7, reducing the load on staff. Zenify recorded a 35% reduction in processing time (approved).
TL;DR
- IVR is an old system, customers have to press a key.
- Voicebot understands voice and responds naturally.
- Operating 24/7, reducing switchboard load.
- Customers with different accents can still handle it.
- Combine people when things are complicated.
