Your agent, now on the phone.
Symphia Voice brings the same resolving, action-taking agent to live phone calls — natural speech-to-speech that understands intent, looks things up, and gets things done.
Capabilities
A phone agent that actually resolves
Everything that makes Symphia chat great, delivered in a voice your customers will happily talk to.
Natural speech-to-speech
Real-time voice that listens, interrupts gracefully, and responds in a warm, human cadence — not a rigid IVR tree.
One brain, two channels
Voice runs on the same agent as chat: same knowledge, same tools, same journeys. Configure once, deploy everywhere.
Acts mid-call
Look up an order, process a refund, book an appointment — the agent calls your APIs live while it's still on the line.
Multilingual
Greet and converse in the caller's language automatically, with consistent quality across every supported locale.
Warm human handoff
When a call needs a person, the agent transfers with full context so your team never asks the caller to repeat themselves.
Safe and on-script
Built-in moderation, scoped secrets, and journey guardrails keep every call compliant and on-brand.
Same configuration
If it works in chat, it works on a call
Voice inherits your knowledge bases, functions, journeys, and brand voice. There's no second agent to build and keep in sync — turn voice on and your existing agent picks up the phone.
- Grounded answers from the same knowledge you already curated
- The same tools and actions, called live during the conversation
- Journeys steer refunds, onboarding, and troubleshooting flows
- Per-call memory and variables, just like the dev chat
Built for trust
Compliant, observable, and in your control
Every call is transcribed and logged to the same console as your chats. Moderation and journey guardrails keep the agent on-script, and a super admin controls whether voice is enabled per workspace.
- Full transcripts and insights in one console
- Tenant isolation and scoped secrets by default
- Per-workspace on/off, controlled by an admin
- Seamless escalation to a human with context intact
Frequently asked questions
Do I have to rebuild my agent for voice?+
No. Voice runs on the same agent brain as chat — your knowledge, tools, and journeys carry over. You enable voice and it's ready.
Can the agent take actions during a call?+
Yes. It calls your connected APIs live — looking up orders, processing changes, booking appointments — while still on the line with the caller.
What happens when a caller needs a human?+
The agent transfers to your team with the full conversation context, so the caller never has to repeat themselves.
How do I turn voice on?+
A super admin enables voice per workspace in Profile settings. When it's on, your team can start calls; when off, the tab stays visible but calling is disabled.
