The challenge
Drivers had to pull over and tap through the app to update delivery status, which was slow and unsafe.
A hands-free voice flow was needed but voice infra was a big lift.
The solution
The team embedded voice into their own app via the MyChatBot Web Voice SDK:
- Voice inside the app, the MyChatBot Web Voice SDK adds inbound (WebRTC) and outbound (Twilio/SIP) calls with a few lines of JS.
- Own voice and instructions, each AI voice agent gets its own voice, language and prompt, fully under the team's control.
- Client-side tools, the agent calls the app's own functions mid-call, navigating the UI, searching, booking, updating records.
- Persistent callers, defaultCallerId keeps a stable identity across sessions, so context follows the user.
- Scales with usage, minute bundles and per-minute overage mean the same SDK serves a prototype and a production app.
A hands-free voice flow shipped in a week, halving app taps and lifting on-time delivery 15%.
