Generic Mute Speech Input Node configuration panel
  • As of Cognigy 4.96.0, AudioCodes Nodes and Generic Voice Nodes are deprecated. Flows with these Nodes continue to work, and you can still edit and clone them as well as export them as a Package. However, you can’t create new ones in Cognigy 4.96 or later.
  • The full removal of AudioCodes Nodes is planned for Q2 2026. After the removal, AI Agents using these Nodes will stop working properly. We strongly recommend migrating to Voice Gateway Nodes before the removal date.

​
Description

This Node controls when speech user inputs can be collected in your Flow. It prevents speech interruptions in specific cases, such as xApp Flows, allowing for a smoother conversation experience. By enabling or disabling speech gathering as needed, you can maintain better control and ensure a seamless workflow in your application.

​
Settings

Do not turn off a speech user input throughout the call to receive additional messages from the user, especially when the AI Agent needs to send multiple messages with time gaps in between.

​
Example

In the following example, the Mute Node allows you to control when speech input is accepted or disabled within the Flow:
  1. Say Node: Hello, you will receive an xApp.
  2. xApp: Init Session Node.
  3. Mute Speech Input (enabled).
  4. Question Node: Please rate your experience with the xApp on a scale of 1 to 5.
    When the Mute Node STT is enabled, the question node will not accept speech inputs or digits as the answer. The user must provide the rating through other means, such as selecting a number using buttons or typing the response. This process ensures that the speech gathering is temporarily turned off during the rating question to avoid unintended interference from background speech.
  5. Mute Node STT (disabled).
    After the rating question, the Mute Node STT is disabled, allowing the subsequent Nodes to accept speech inputs normally.
