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: 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 selected 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.

Select voice

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

Recommended voices

There are many voices to choose from. So you do not have to test them all yourself, our Conversation Experience Team has reviewed the voices for clarity, pronunciation, and naturalness, even for more complex content such as numbers, URLs, anglicisms, or spontaneous colloquial speech. 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 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, switch the voice.

One language or multiple?

Choose the voice that sounds most natural for your use cases. Test the desired voice before use with typical conversation scenarios, especially if numbers, proper names, or technical terms occur frequently. Differences are best seen in practical use.

Set form of address

Decide 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 selected form of address determines only the use of “You (formal)” or “You (informal)”. It does not affect the agent's general language style. Polite and respectful behavior is stored by default, regardless of the selected form of address.

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

Customize greeting text

You can individually define your AI agent's greeting text 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 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 ensures 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 first need to be activated. If you have any questions, contact sipgate customer support.

What options are available?

Under the interruption section, choose between two settings:

• Agent speaks to the end without interruption: The agent cannot be interrupted while answering and speaks its entire response to the end.
• Caller can interrupt agent:

  • As soon as the caller speaks, the agent stops and listens.
  • The greeting message is excluded from this and cannot be interrupted for data protection reasons.
  • If the agent is interrupted, the already generated response remains visible in the transcript, even if it was not spoken in full.

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.

Silence response time

The silence response time determines how long the AI agent waits after the caller has stopped speaking.

It is set by default so that conversations feel as natural as possible. If your agent responds too quickly or too slowly, contact Customer support. The response time can be adjusted if needed.

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 logs directly.
