Voice & language

In this section, you define how your AI phone assistant sounds and how it speaks with callers. The voice, language and greeting settings 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: German, English, Spanish, French, Polish, Dutch, Arabic, Turkish, Russian.

The language determines how your agent understands and responds to callers. The agent always responds in the set language, regardless of which language the caller speaks.

Note: If your company regularly receives calls in different languages, it is recommended to set up a separate agent for each language.

Choose voice

Choose a voice that suits your company and target audience. The voice influences how professional and understandable your agent is perceived to be.

Recommended voices

There are many voices to choose from. So you don't have to test them all yourself, our Conversation Experience team has evaluated the voices for comprehensibility, pronunciation and naturalness, even with more complex content such as numbers, URLs, anglicisms or spontaneous colloquial language. These four voices were particularly convincing:

Voice	Language	Character
Philipp	German	Neutral & reliable
Ramona	German	Calm & professional
Benjamin	German	Efficient & clear
Laura	German	Direct & professional

Note on proper names: Company names, street names and technical terms are pronounced differently depending on the voice. Test your agent with a test call before using it. If a voice does not pronounce your company name correctly, change the voice.

Monolingual or multilingual?

If your agent speaks only German, choose a voice from the category German. If anglicisms or English technical terms frequently occur in your conversations, voices from the category Multilingual are better suited.

Set form of address

Specify whether your agent addresses callers with you (formal) or you (informal) addresses them.

• you (formal) (Formal): suitable for customer service, B2B and conservative industries

• you (informal) (Informal): suitable for modern companies and younger target groups

The form of address applies to all conversations of this agent and should match your company communication.

Customize greeting text

You can individually define the greeting text of your AI Agent and adapt it to your company communication.

Important: The greeting text must include a note that it is a digital service. The text is reproduced verbatim, regardless of the language set.

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 makes conversations more natural and reduces waiting time.

Where can 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 first need to be activated. If you have any questions, please contact sipgate customer support.

What options are available?

Under interruption, choose between two settings:

• Agent finishes speaking without interruption: The AI Agent completes its speaking turn fully before responding to the caller.

• Caller can interrupt agent: As soon as the caller speaks, the agent stops and listens.

Note: 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)

Optionally, background noises such as office sounds can be enabled. This setting shapes the atmosphere of the conversation and can create the impression of a real workplace.

Language of the conversation summary

Specify in which language conversation summaries are created.

Example: Your agent conducts conversations in English, but your team works in German. Set the summary language to German so that all employees can use the logs directly.
