Compare · ElevenLabs
ElevenLabs gives it a voice. Zumu gives that voice a brain, hands, and a memory.
ElevenLabs and Zumu solve different layers of the same problem. ElevenLabs makes a voice sound real. Zumu is the layer above it: the reasoning, the phone line, the actions, and the memory that turn a voice into an agent that gets things done.
- ElevenLabs is a supported voice provider inside Zumu
- Different layers, not a competition
- Any major model, any voice, one agent
Different layers, not a fight
A great voice and a great agent are not the same job
ElevenLabs is a genuinely strong voice engine. If a voice needs to sound convincing and natural, ElevenLabs is one of the best places to start. Plenty of teams already do.
Zumu is not trying to out-voice a voice company. Zumu sits a layer above the voice engine. It decides what the agent says next. It places and controls the actual phone call. It calls out to your real systems mid-conversation. It remembers the caller the next time they get in touch.
The two are not really in competition. ElevenLabs is one of the text-to-speech providers Zumu can use. Keep the voice you already like, and Zumu builds the agent around it.

Being straight about this
When ElevenLabs alone is the right call
If all you need is a voice that sounds real, for an app, a game character, a video narration, ElevenLabs on its own is the right tool. You do not need an orchestration layer, a phone system, or a memory store for that job. Reach for Zumu when the voice needs to become a phone call: something that listens, decides, acts on your systems, and remembers who it is talking to.
What carries across
What carrying the voice across looks like on Zumu
The voice is only the start. Here is what the agent does once the voice is talking.
Real actions, not just a reply
Tool and MCP calls run mid-conversation: book a meeting, look something up, write to a CRM, while the caller is still on the line.
A caller the agent already knows
Persistent memory recognizes a returning caller and carries a verified fact forward, whether they call, chat, or email.
One agent, every channel
Define an agent once. The same brain, knowledge, and tools run the phone, the widget, and email from one configuration.
Proof, not just a transcript
Every conversation is transcribed and scored: outcome, sentiment, escalation, and friction, not a raw log nobody reads.
