1

Configure Voice Settings

Open the voice selection dropdown menu. Listen to the available voice samples and select the voice you want to use for the agent.Custom Voices: You can also add voices from the ElevenLabs community or clone voices by clicking “Add custom voice.”Additional voice settings:
  • Voice temperature: Make the voice more variant or stable
  • Voice speed: Make the agent speak faster or slower
  • Voice volume: Make the agent speak louder or quieter
  • Voice model (if applicable): When using certain voice providers, you can choose between different models. Check the dashboard for detailed nuances of each model.

Select Language of Agent

Pick the language(s) the agent will understand and speak. This affects speech recognition, voice pronunciation, and the language the agent responds in — you do not need to add a “respond in X” instruction to your prompt.To support multiple languages, switch the selector to Multiselect and pick the specific languages you want. For best accuracy, prefer a single language when possible.
3

Select a Language Model

Select the model you want to use for the agent. You can override this within individual nodes. Optionally tune the LLM temperature to make answers more variant or more stable.We recommend starting with GPT-4.1, which offers an optimal balance of:
  • Response quality
  • Latency
  • Cost-effectiveness
4

Write Global Prompt

Specify the agent’s persona, identity, guardrails, etc. This text is available in every node and influences all response generation.
5

Configure Knowledge Base

Supply context to the agent via documents, URLs, and texts. Read more in the Knowledge Base guide.
6

Configure Speech Settings

Options for fine-tuning how your agent interacts with users:
  • Background sound: Select a background sound that plays throughout the call (e.g. call center ambience) to make the conversation more human-like
  • Responsiveness: How responsive the agent is. Set lower for slower responses — reducing by 0.1 adds 0.5 seconds of agent wait time
  • Interruption Sensitivity: How quickly the agent gets interrupted. Set lower for more resilience to background speech
  • Backchanneling: How often and what words the agent uses to acknowledge users
  • Boosted Keywords: Biases speech recognition toward certain words like brand names or people’s names
  • Speech Normalization: Converts dates, currency, numbers into plain words to prevent mispronunciation
  • Reminder frequency: How often the agent reminds the user when they are inactive
  • Pronunciation: Set up a pronunciation guide for specific words
7

Configure Call Settings

  • Voicemail: Set up voicemail detection and what to do when voicemail is detected
  • End call on silence: End the call if the user is inactive for a configured duration
  • Call duration: Set a maximum call duration
  • Pause before speaking: At the start of the call, if the agent speaks first, it waits for the configured duration before speaking — useful when the user is still picking up
