-                    Welcome to our translation hub! Please note that this space is limited to one speaker at a time. If using the live translation space, sharing the room code to listeners on another IP address may not work due to different replicas. Use headphones if you are both the speaker and listener to prevent feedback.

-                    Our Real-Time Translation model is a research model and is not released for production deployment. Please use a microphone with noise cancellation (e.g., a smartphone) to avoid model hallucination on noises. It works best if you pause every couple of sentences, or you may wish to adjust the VAD threshold in the model config. Real-time performance may degrade if you try streaming multiple speakers simultaneously.
