Speed control

The speed control feature allows you to adjust how quickly or slowly your agent speaks. This can be useful for:

• Making speech more accessible for different audiences
• Matching specific use cases (e.g., slower for educational content)
• Optimizing for different types of conversations

Speed is controlled through the speed parameter with the following specifications:

• Range: 0.7 to 1.2
• Default: 1.0
• Type: Optional

Open your agent in the dashboard, navigate to the Voice tab, and adjust the speed control. Save your changes.

elevenlabs agents pull --agent "<agent-name>"

Set conversation_config.tts.speed:

{
  "conversation_config": {
    "tts": {
      "speed": 1.1
    }
  }
}

elevenlabs agents push --agent "<agent-name>"

from elevenlabs import ElevenLabs

elevenlabs = ElevenLabs()

elevenlabs.conversational_ai.agents.update(
    agent_id="agent_7101k5zvyjhmfg983brhmhkd98n6",
    conversation_config={
        "tts": {"speed": 1.1},
    },
)

import { ElevenLabsClient } from "@elevenlabs/elevenlabs-js";

const elevenlabs = new ElevenLabsClient();

await elevenlabs.conversationalAi.agents.update("agent_7101k5zvyjhmfg983brhmhkd98n6", {
  conversationConfig: {
    tts: { speed: 1.1 },
  },
});

The speed parameter affects the pace of speech generation:

• Values below 1.0 slow down the speech
• Values above 1.0 speed up the speech
• 1.0 represents normal speaking speed

• Start with the default speed (1.0) and adjust based on user feedback
• Test different speeds with your specific content
• Consider your target audience when setting the speed
• Monitor speech quality at extreme values
