The team wanted a voice assistant that could search products, answer questions and guide checkout, but building voice infrastructure from scratch was months of work.
Off-the-shelf bots couldn't drive their custom UI.
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.
With client tools driving the UI, voice shopping shipped in a week and AOV rose 19%.
