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 the language of the AI Agent

Choose the language in which your agent should conduct conversations. Available options are: German, English, Spanish, French, Polish, Dutch, Arabic, Turkish, Russian.

The language determines how your agent understands and responds to callers. The agent always replies 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 affects how professional and understandable your agent is perceived to be.

Recommended voices

There are many voices to choose from. So that you do not have to test them all yourself, our Conversation Experience Team has evaluated the voices for clarity, pronunciation, and naturalness, even with more complex content such as numbers, URLs, anglicisms, or spontaneous colloquial language. These four voices stood out in particular:

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

Note on proper names: Company, street, 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, switch voices.

Monolingual or multilingual?

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

Set form of address

Define whether your agent addresses callers as you (formal) or you (informal) .

• 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 define your AI Agent’s greeting text individually and adapt it to your company communication.

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

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

Which options are available?

Under interruption, you can choose between two settings:

• Agent finishes speaking without interruption: The AI Agent completes its speaking turn in full 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)

Background noise such as office sounds can optionally 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 the language in which 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 transcripts directly.
