AI-Personas
Find an AI-Persona, start a practice conversation and see what happens during and after the call.
Choose an AI-Persona, read its scenario and practise a conversation. You need a valid license. Sleak gives you feedback after the conversation.
Find and start a persona
- Open AI-Personas in the navigation.
- Search by name or filter by Difficulty, Conversation type or Teams.
- Select a persona to read its scenario.
- Click Start conversation or Start chat.
The list contains personas shared with you and your own personas. Recently used and Recently shared with you each show up to four. Tags and Created by are under More filters. Sort orders by name or newest first.
You can create your own persona with New Persona. See AI-Personas Management for the builder and sharing.

Tip
During a voice conversation
| Control | Action |
|---|---|
| Microphone | Mutes or unmutes you. |
| Camera | Turns the camera on or off. |
| Screen share | Shares your screen if your workspace allows it. |
| Timer | Shows the conversation length. |
| End | Ends the conversation and starts analysis. |
When no audio comes through
Follow the audio notice to check the selected microphone, permissions or network. Ask your Admin to run the connection test if the connection fails. Your network must allow *.livekit.cloud.
Pause a conversation
- Click Pause.
- Click Continue to resume, or End and analyse to finish.
You can return later from the persona or a Paused conversation under Conversations. Use Go to conversation to resume it. Analysis starts only after you end it. Pauses do not count towards its duration. Chat conversations and assessments cannot be paused.
The coach
Conversation phases tracks the phase you are in. Show answer help offers a sentence you could say next. You must turn answer help on yourself. Check suggestions before using them. Assessments do not include the coach.
Chat conversations
A chat persona uses text instead of voice. The start screen has no voice/chat switch. The author can change its format through the builder chat and publish the change.
- Choose the language in Chat settings.
- Click Start.
- Type a message.
- Press Enter to send it. Use Shift+Enter for a new line.
- Click End chat when finished.
| Option | Use |
|---|---|
| + | Adds up to four image or document attachments per message. You can also drop or paste files. |
| Microphone | Dictates text that you can edit before sending. |
The persona waits while you type. It checks in after two minutes of inactivity and ends the chat after two further minutes. Chat analysis has no audio recording or speech metrics.
After the conversation
A conversation ends when you click End, the persona hangs up or the connection drops. Rate the conversation under How was the conversation? and add a comment if needed. Open To analysis for your feedback or use the repeat button to practise again.
Assessments
Open assessments from your program. The start screen shows remaining attempts and any unmet conditions. Chat assessments are not available.
