# Assistant during calls

On a call between you and someone else, on Noema, the Windows app or a desk phone, the AI is on the line with you. It stays silent and only listens. It answers out loud when you start a sentence with a **wake word**: **Logica** or **Λότζικα**.

- *"Λότζικα, πρόσθεσε τη Μαρία στην κλήση."*
- *"Logica, add extension 104."*
- *"Λότζικα, τι ώρες είμαστε ανοιχτά το Σάββατο;"*

Both of you hear the answer. Then it goes quiet again.

## When the wake word applies

| Call | Wake word |
| --- | --- |
| **Between people** - you and a customer or colleague | **On by default.** The AI stays silent until you say **Logica** or **Λότζικα**. |
| **The AI answers the caller itself** | **No effect.** The AI talks normally. The wake word matters only if you also set sleep phrases and someone put the agent to sleep. |

## How it works

- **Wake word every time** — Start every request with the wake word. Without it the assistant stays silent, even right after it answered.
- **Only you wake it** — The person you are talking to cannot wake it, even by saying the word.
- **Cut it off** — Say the wake word again while it speaks.
- **Which calls** — Calls Voice Logica analyses: Noema, the Windows app, a desk phone or softphone on your extension.

## Set it up once

1. **Choose the assistant.** It is the **Default analysis agent** in **Telephony - [Call settings](https://docs.voicelogica.ai/telephony/call-settings/)**, with **Analyze calls by default** on. A user whose phone settings override the company's uses their own analysis agent. It needs a voice and a non-realtime model.

2. **Check the wake words.** They are in **Telephony - Call settings - Keypad codes and wake word**, up to 5 (a user can have their own in their seat). Every company starts with **Logica** and **Λότζικα**; delete either one, and with none left nothing wakes the assistant. Never use a person's name, like Δημήτρη: the assistant would wake every time someone says it. Switch the wake word off and the assistant never speaks on your calls.

3. **Let it add people.** On the same agent, **Skills - Tools & Workflows - Add Participant** on. Colleagues are added by extension and ring on their app and desk phone. To add customers and other outside numbers, also switch on **Allow external numbers**.

4. **Save the people you add often.** The assistant finds people by name among your **team members** (Telephony - Active directory) and your **contacts** (with their phone number). Numbers that are not saved anywhere can go in the agent's prompt, for example *"Our accountant is Nikos, +30 210 1234567"*.

## Add someone to the call

Say the wake word and who to add: *"Λότζικα, πρόσθεσε τον Νίκο"*.

- **One person matches:** it dials them and tells you they are being connected. Nobody is dropped.
- **Several match:** it asks which one, for example *"Νίκο Παπαδόπουλο ή Νίκο Γεωργίου;"*. Answer with the wake word: *"Λότζικα, τον Παπαδόπουλο."*
- **Nobody matches:** it asks for the number. Say it: *"Λότζικα, πρόσθεσε το 6912345678."*

## With Claude or ChatGPT

Connected to [Claude or ChatGPT](https://docs.voicelogica.ai/integrations/claude-chatgpt/)? Ask:

- *"Which words wake my assistant?"*
- *"Change the wake word to Βοηθέ"* or *"turn off the assistant during my calls"*.
- *"Turn on Add Participant and let it call outside numbers."*
- *"Save Maria Papadopoulou, 6912345678, as a contact."*

Ask *"how do I talk to the assistant during a call?"* for the full guide.

## Troubleshooting

**It does not answer**

Start with the wake word, clearly, at the start of the sentence. Check that **Analyze calls by default** is on and that the **Default analysis agent** has a voice and **Enable standby** on. A call that is not analysed has no assistant.

**It wakes when nobody called it**

A wake word that sounds like a common word or a name. Pick a rarer one on **Advanced - Standby**, or keep **Logica** / **Λότζικα**.

**It says it cannot add the person**

Turn on **Add Participant**. For a customer or any number that is not a colleague's extension, also turn on **Allow external numbers**.
