Choosing a voice and setting the greeting
How Cleo sounds is set per phone line: which voice, which language and the sentence she answers with. Testing happens right from the browser — you hear the result within a minute.
Before you start: open the main menu
Assistant, pick your assistant and click Voice settings. The voice lives under the Voice & greeting tab.Voice, language and greeting
1
Pick a voice persona
Choose from the catalogue who answers your calls — every persona has its own voice and character.
2
Set the language
Choose the language the assistant speaks, for example Dutch. Summaries follow the same language.
3
Write the greeting
One short sentence works best, for example: "Good afternoon, this is Cleo from Jansen Real Estate. How can I help you?"
Listen via a test call
Click Test call to talk to your assistant straight from your browser — no real phone call needed. Test your capabilities too: ask a question from the Library or ask for an appointment. Test calls count as regular call minutes.

A custom voice (advanced)
By default your assistant speaks with the built-in speech engine (Gemini Live). Want your own cloned voice — say, your office identity — then set the engine to Pipeline — custom voice under Call settings → Speech engine.
Voice ID — Clone a voice with about 10 seconds of audio (in LiveKit Cloud under Voices) and paste the
v_… id into the Voice ID field. Leave empty for the platform's default voice.Recognition terms — Enter company and product names (comma-separated) so they're understood correctly — useful for jargon and proper names.
Common problems
The assistant speaks the wrong language
The language is set per phone line under Voice & greeting. Set it to your language and start a new test call.
Names or jargon are misheard
Add them as recognition terms under Call settings → Speech engine (available on the pipeline engine).
