AI Real-Time Subtitles

Feature Introduction
After integrating TUIRoomKit, you can enable the AI real-time subtitle feature by clicking "AI Assistant" in the bottom bar. The feature is achievable:
AI real-time subtitles: Display the discussion content during the meeting process in the form of subtitles.
AI real-time meeting minutes: Record the discussion content during the meeting process in text form.
Note:
Using this feature requires subscribing to TUIRoomKit Activate the Service. Except for normal call charges (Audio/Video Duration Billing Instructions); when this feature performs speech to text, additional AI Intelligent Identification fees will occur. For details, see AI Intelligent Identification Billing Instructions.
Click AI assistant in the bottom bar.

Feature Integration
Prerequisites for Access
Turn on the "AI assistant" button in the bottom bar.
ConferenceSessionImpl.sharedInstance().isShowAISpeechToTextButton = true;
Enable AI Real-Time Subtitles
Enable the AI real-time subtitle feature, which actually starts an AI transcription task. During this process, the backend will use robot stream pulling to perform real-time speech recognition and send subtitles and transcription messages. For more information on parameter configuration for enabling AI transcription tasks and querying transcription task status, please refer to AI service-related interfaces.
After a room is created, you can enable the AI real-time subtitle feature by using the following example code.
Note:
The voice transcription feature requires a key to be enabled. Since code leakage may lead to the leakage of SecretId and SecretKey, and threaten the security of all resources under the account. It is recommended to use the key in a more secure way. For details, see Recommended Cloud API Key Security Solutions. The key can be obtained by going to API Key Management.
