Thank you again！

As we continue to update this dataset, we will follow your advice to adjust these parameters accordingly. your reply has been extremely helpful in guiding us toward more optimized data acquisition.

Thank you so much for your valuable suggestions.In our current setup,we use a relatively high line density and depth. As you pointed out,these settings likely contribute to the lower effective frame rate,and may have placed too much emphasis on clarity,maybe we need a different device for testing.

We purchased a device from Focus&Fusion Co., Ltd. I suspect that the reason for the repeated frame may be related to the speaking speed, as we do not to capture long conversations.
We hope to receive some guidance and suggestions from you, which will be more helpful for us to update this database.

Thanks for your attention.Actually,due to patient cooperation issues, some data is difficult to consistently align with the probe (patients stroke are hemiplegic/drooling, we hope that this part of the data may be helpful in clinical).So, the core of data is normal, and patients only collect small.
