Intelligent Media Services:Custom sensitive words

Last Updated:Dec 15, 2025

You can configure custom sensitive words in the built-in Speech-to-Text (STT) node.

Feature introduction

This feature lets you define a list of sensitive words. Then, the STT node detects these words in real time. If a sensitive word is detected, the system automatically redacts it in the client-side subtitles by replacing it with an asterisk (*).

Note

After a sensitive word is detected, the system passes the redacted content to the large language model (LLM) node.

Configure sensitive words

  1. Prepare a sensitive word file: Add the words you want to block to a TXT file.

    Note
    • The language of the sensitive words must match the language model that is configured in the console.

    • Each file can contain up to 500 words. Each word can be up to 10 characters long. The total file size cannot exceed 100 KB.

    • The file must use UTF-8 encoding. The words cannot contain punctuation or special characters.

  2. Configure the STT node: Upload the sensitive word file to the STT node in the workflow.
