# Voice & language
In this area, you define how your AI phone assistant sounds and how it speaks with callers. The settings for voice, language, and greeting apply to all conversations of this AI Agent and can be adjusted at any time.
### Select AI Agent language
Choose the language in which your agent should conduct conversations. Available options are German, English, Spanish, French, Polish, Dutch, Arabic, Turkish, and Russian. The selected language determines how the AI Agent understands callers and how it responds to requests.
### Choose a suitable voice for the phone assistant
In addition to the language, you can select a suitable voice for your AI Agent. The voice influences how the phone assistant is perceived and how clear the pronunciation is. The selected voice applies to all conversations of this agent.

**Tip for proper nouns:** Company names, street names, or technical terms are sometimes not pronounced correctly. Test your AI Agent with a test call and, if necessary, switch the voice or write to sipgate customer support.

### Customize greeting text
You can individually define the greeting text of your AI Agent and adapt it to your company communication.
{% hint style="info" %}
**Important:** For legal reasons, the greeting text must refer to the digital service. The wording is reproduced exactly, regardless of the selected language.
{% endhint %}
### Set form of address
Specify whether the AI Agent should address callers formally with **you** or informally with **you** . The form of address affects the entire conversation and should match your target audience and the intended use of your phone assistant.
### **Barge-In**
With Barge-In, you determine whether callers can interrupt the AI Agent while it is speaking. If the function is active, the agent stops immediately as soon as the caller speaks and listens. This creates more natural conversations and less waiting time.
**Where do I find the setting?**
In the logged-in area under Account management → AI Agents → Select agent → Agent settings. Depending on the account configuration, the function may need to be activated first. If you have any questions, please contact sipgate customer support.
**What options are available?**
Under Interruption, you can choose between two settings:
* **Agent finishes speaking without interruption:** The AI Agent completes its turn in the conversation before responding to the caller.
* **Caller can interrupt agent:** As soon as the caller speaks, the agent stops and listens.
**Important:** Barge-In is not enabled by default. To allow callers to interrupt the agent, you must select and save the corresponding option in the agent settings.
### Enable background noise (optional)
Background noise can optionally be enabled, such as office sounds. This setting shapes the atmosphere of the conversation and can give the impression of a real workplace.
### Language of the conversation summary
Regardless of the language of the call, the language for conversation summaries can be set. This makes it possible, for example, to summarize conversations in a different language than the one in which they were conducted.
