Node - Audio Notification

Node Function: When the workflow reaches this node, it can automatically play a text message or audio file to the workflow trigger initiator.

Example: When confirming task completion, if the operation succeeds, play “Operation successful” to the operator; if it fails, play “Operation failed.” The operator does not need to check the interface to know the result, improving message delivery efficiency.

This node supports playing a fixed audio file or text-to-speech content.

Audio​

Under Audio mode, you can either:

  • Select a system preset sound effect
  • Upload a custom audio file

Custom audio files must be in MP3 or WAV format and no larger than 10MB.

Voice​

Under Voice mode, you can configure the language, tone, and speech rate to play a specified text.

Click the Tryout button to directly play the text entered in the “Content” field.

Voice Playback Rules​

  1. Playback Is Only Available to the Workflow Trigger Initiator

    Ensure that the workflow containing the Audio Notification node is directly triggered by a user. Workflows triggered by another workflow, public form, API, or similar sources will not play audio.

    For example:

    If a user edits a field and triggers Workflow A, and Workflow A creates a record that triggers Workflow B, then:

    • The Audio Notification node in Workflow A will play audio.
    • The Audio Notification node in Workflow B will not play audio because the trigger initiator is “Workflow,” not a user.

    How to check the workflow trigger initiator:
    Open the execution history of the workflow containing the Audio Notification node and review the trigger initiator.

  2. Supported Platforms

    Voice playback is supported only on:

    • PC Web
    • Mobile App

    Playback is prioritized on PC Web. If the PC is not logged in, and the Mobile App is active in the foreground, playback will occur in the app. Playback is not supported when the app runs in the background.

    Due to mobile browser security restrictions, audio playback is not supported in mobile web environments (H5), including:

    • Mobile browsers
    • Mini Programs
    • Third-party integrations (e.g., WeCom, DingTalk, Feishu)

  3. Workflow Trigger Limitations

    The Audio Notification node can only be added to the following types of workflows:

    • Workflows triggered by worksheet events
    • Workflows triggered by buttons
    • Packaged business processes

    The following workflow types do not support the Audio Notification node because their trigger initiator is “Workflow,” not a user:

    • Date field–triggered workflows
    • Scheduled workflows
    • Webhook-triggered workflows
    • Subprocesses

    Voice playback is supported when calling an packaged business process from:

    • Custom page buttons
    • API query fields
    • Control events

    Important:
    If a button-triggered workflow calls an packaged business process, the Audio Notification node inside the packaged business process will not play, because the trigger initiator is “Workflow.”

    To enable playback, place the Audio Notification node directly inside the button-triggered workflow.
