Audio Risk Identification Feature

Updated: March 16, 2026

I. Use Cases

Commonly used in live streaming scenarios with strict compliance requirements or regulatory oversight, where it is necessary to strictly control the speech of instructors, guests, etc., to prevent negative impacts.

II. Version Description

The Audio Risk Identification feature offers two versions to meet different scenario needs:

Key Differences Between the Two Versions

• Finance Edition: Uses preset financial risk review strategies covering common financial compliance risk points (e.g., illegal stock recommendations, guaranteed returns), usable without additional configuration.
• LLM Edition: Based on a large language model, users can customize compliance prompts to flexibly define review focus areas and violation criteria, adapting to personalized business scenarios.

III. Operation Steps

1. Backend Settings

(1) Log in to the Polyv backend, navigate to the compliance settings of a single channel, and find the "Audio Risk Identification" feature.

(2) Finance Edition: Configure the corresponding review strategy. a. Different levels of review strategies have varying degrees of scrutiny during live streaming. Click "View Strategy Details" next to the toggle to review. Example (partial screenshot): b. Configure prohibited words/sensitive words.

Click "Configure Prohibited Words" to navigate to the Platform Settings -> Platform Prohibited Words -> Audio Review page for configuration.

Prohibited words are divided into two types with different trigger effects:

After configuration, the system will detect the instructor's live audio in real-time:

• Hitting a Sensitive Word: The corresponding role (monitor/host/assistant) receives a pop-up alert.
• Hitting a Prohibited Word: The live stream is interrupted directly, and a notification is sent.

(4) LLM Edition: Configure the review switches.

The LLM Edition includes two independent switches that can be flexibly enabled as needed:

a. LLM Review Configuration

After enabling the "LLM Review" switch, enter custom review rules in the "Compliance Prompt" configuration area:

b. Prohibited Word Review Configuration

After enabling the "Prohibited Word Review" switch, click "Configure Prohibited Words" to navigate to Platform Settings -> Platform Prohibited Words -> Audio Review for configuration:

Prohibited word trigger rules:

Configuration suggestions are the same as the Finance Edition. Configure prohibited words with caution.

c. Combined Usage Instructions

The two switches in the LLM Edition are independent of each other, supporting the following combinations:

• Enable only "LLM Review": Uses custom prompts for intelligent review.
• Enable only "Prohibited Word Review": Uses only the sensitive/prohibited word list for matching.
• Enable both: Audio content undergoes dual review; any trigger will result in corresponding alerts/actions.

b. Click "View Example" to see the pop-up alert style.

IV. Version Feature Comparison

V. Notes

1. The Audio Risk Identification feature requires sufficient account balance to function normally. If the account balance is insufficient, the feature cannot be used. Usage of this feature also incurs costs. Please consult your business manager for details.

2. Version Activation Instructions: The Finance Edition and LLM Edition are activated on a one-or-the-other basis. Users can choose to activate one version based on business needs. Contact your business manager to activate or switch versions.

3. LLM Edition Prompt Suggestions:

   • Prompt length is recommended to be between 200-1000 characters. Too short may lead to unclear review standards, too long may affect review efficiency.
   • It is recommended to include clear criteria descriptions (Violation/Suspicious/Pass) in the prompt.
   • For first-time use, it is advisable to test the prompt effect with test audio before officially enabling it.

4. If the audio has accents or non-standard pronunciation, there is a possibility of system misjudgment.
