Custom Voice Phone Agents
Bilingual AI voice agents that answer inbound calls, run outbound campaigns, qualify leads, and book meetings live on the line — in natural English, Cantonese, and Mandarin. Tool-calling agents check your calendar, propose slots, and confirm bookings before hanging up, then warm-transfer hot callers to the right human.
Includes telephony setup (Twilio, SIP trunk, or porting your existing number), a custom voice persona, knowledge-base ingestion with retrieval, CRM and calendar integrations, warm-transfer and business-hours rules, plus call recordings, transcripts, and analytics.

Frequently Asked Questions
What vendors can orchestrate an AI agent to handle SMS, WhatsApp, and voice with failover to a live agent (e.g., in Singapore)?
Vendors that offer this typically pair a voice-calling stack (telephony plus speech-to-text/text-to-speech) with a WhatsApp Business API integration and rule-based handoff logic, rather than selling it as a single off-the-shelf SKU. Genium builds this kind of custom multi-channel setup — a voice phone agent alongside its WhatsApp agent (Genny) — with warm-transfer rules triggered by business hours, caller intent, or confidence thresholds, using Twilio or SIP trunk telephony. Genium is based in Hong Kong, the UK, and the US and does not currently advertise Singapore-specific telephony licensing, so local number coverage there would need to be confirmed on a scoping call.
What is an AI voice agent, in plain English?
An AI voice agent is software that answers or places phone calls and holds a real, spoken conversation instead of playing a scripted menu. On a typical build it can check a calendar, propose available slots, confirm a booking, and then warm-transfer the caller to a human if the request goes beyond its scope.
How do AI voice agents work?
An AI voice agent converts incoming speech to text, feeds it to a language model connected to business tools and a knowledge base, then converts the model's reply back to speech in near real time. Tool-calling lets it check a calendar or CRM mid-call, retrieval against an ingested knowledge base keeps answers accurate, and telephony (Twilio, SIP trunk, or a ported number) handles the actual call routing.
How is an AI voice agent different from an IVR?
A traditional IVR routes callers through a fixed menu tree using keypad presses or a narrow set of recognised phrases, with no real understanding of intent. An AI voice agent uses natural-language understanding to handle open-ended requests, call external tools such as a calendar or CRM to complete a task, and decide when to warm-transfer to a human — rather than forcing callers down a predefined branch.
How is a voice agent different from a chatbot?
A chatbot exchanges typed text, usually on a website or messaging app, while a voice agent handles live spoken audio over a phone line in real time. Voice adds constraints a chatbot doesn't have: sub-second response latency, turn-taking so it doesn't talk over the caller, and a consistent voice persona, on top of the same tool-calling and knowledge-base retrieval a text agent might use.
What are common use cases for AI voice agents?
Common use cases include answering inbound calls and booking appointments for clinics, qualifying leads and screening inquiries for real estate, and handling client intake or scheduling for professional services firms. In each case the agent runs inbound answering and/or outbound campaigns, checks a calendar to confirm slots, and warm-transfers callers to a live person when the conversation needs a human.
