Voice Setup

Celune's voice mode lets your Agent Lead speak out loud — delivering updates, summaries, and responses using text-to-speech powered by ElevenLabs. This guide covers how to enable voice, choose a voice, and troubleshoot common issues.

Requirements

Before enabling voice mode:

Plan: Voice mode is available on Pro, Team, and Enterprise plans. It is not available on Spark (free).
Browser: A modern browser with Web Audio API support — Chrome, Firefox, Edge, or Safari 15+.
Microphone (optional): Required only if you want to speak to your Agent Lead. Text input works without a microphone.

Choosing a Voice

You choose a voice during onboarding. To change it later:

Go to Settings → Agent → Voice.
Click the play button next to each voice to preview it.
Select the one you want.
Click Save.

The change takes effect on the next response.

Available Voices

Celune offers a curated set of voices from the ElevenLabs library, organized by character style:

| Voice Style | Characteristics | | ----------- | ---------------------------------------- | | Neutral | Clear, professional, broadly accessible | | Warm | Friendly, conversational, approachable | | Authoritative | Confident, structured, deliberate | | Calm | Measured, thoughtful, low-stress tone |

Within each style, voices vary by gender, accent, and tempo. Preview each to find the one that feels right for your Agent Lead's personality.

How Voice Responses Work

When you send a message via voice mode, your Agent Lead:

Processes your input (text or transcribed speech).
Generates a text response.
Converts the full response to audio via ElevenLabs.
Plays the audio in your browser.

The response plays in full before the next input is accepted. This prevents cut-off audio and feedback loops.

Voice responses are streamed through Celune's server. Your browser does not connect directly to ElevenLabs.

Using Your Microphone

To speak to your Agent Lead instead of typing:

Click the microphone button in the chat input area.
Allow browser microphone access when prompted (one-time prompt).
Speak your message. The input auto-submits when you stop speaking.

After your Agent Lead finishes responding, the microphone activates again automatically (600ms delay to prevent feedback). You can also click the microphone button manually.

Browser Microphone Permissions

If microphone access was previously denied:

Chrome: Click the lock icon in the address bar → Site settings → Microphone → Allow.

Firefox: Click the microphone icon in the address bar → Allow.

Safari: Go to Safari → Settings → Websites → Microphone → set app.celune.ai to Allow.

Toggling Voice On and Off

To disable audio responses while keeping microphone input:

Go to Settings → Agent → Voice.
Toggle Enable Voice Responses off.

Your Agent Lead continues responding normally — responses just appear as text without audio playback.

To disable voice mode entirely:

Use the text input field instead of the microphone button. Voice mode does not activate unless you click the microphone.

Troubleshooting

Audio doesn't play

Check your browser volume and system volume.
Make sure the browser tab is not muted (right-click the tab in Chrome to unmute).
Try a different browser.
Confirm your plan includes voice mode — Spark (free) does not.

Microphone not detected

Confirm microphone access is granted for app.celune.ai in your browser settings.
Try refreshing the page after granting permissions.
Make sure no other application has exclusive control of the microphone.

Response cuts off mid-sentence

This can happen if the browser tab loses focus during audio playback. Keep the tab active while audio plays.
If the problem persists, report it to hello@celune.ai with your browser version and OS.

Voice changed unexpectedly

Check Settings → Agent → Voice — the voice setting is workspace-level, so an admin may have changed it.
