🎙️ Speech Recognition Language Can Now Be Selected from a List​

The specification of speech recognition language, which previously required direct input of language codes, can now be selected from a searchable list. You can also select multiple languages.

How to Use​

You can select the speech recognition language from "Speech Recognition Settings" in the AI Avatar settings screen.

Also, if you select multiple languages, you can switch the speech recognition language from the toolbar menu during normal voice conversation.

🗨️ Reviewed User-Side Transcription Display in Realtime Voice​

In realtime voice conversations, user (your own) speech transcription bubbles are now hidden by default. This is a measure against the problem of text different from actual speech being displayed due to misrecognition or noise.

AI Avatar speech transcriptions will continue to be displayed as before.

How to Use​

You can toggle the user-side transcription display ON/OFF from the Realtime settings in the AI Avatar settings screen.

🔧 Other Adjustments​

• Made adjustments to AI Avatar thinking logic

📝 Prompt History Feature​

History is now kept each time you change and save AI Avatar prompts.

You can easily roll back to past prompts from the list, so please use this when adjusting prompt content, etc.

How to Use​

You can call it from the "History" button in the upper right of each prompt in the AI Avatar settings screen.

Clicking a history item will reflect it in the current prompt (it will not be saved).

• History is saved for up to 25 items, and when full, old ones are automatically deleted
• If you favorite with the ⭐ button, it will not be automatically deleted
• You can also manually delete from the 🗑 button

🔧 Feature Enhancements and Bug Fixes​

.rad File (3DGS Streaming File) Related​

• .rad files can now be previewed in the Media Library
• Sped up loading and display of .rad files

Movement Range Restriction Display Feature Added (When Grid Display is Enabled)​

The range set in "Movement Range Restriction" in Scene Settings can now be visually confirmed as a grid in 3D space.

You can switch it with the "Show Grid" option in 3D screen > Settings dialog ⚙️.

Reload Feature Added to Preview​

Added a button to reload only the preview to the toolbar at the top of the preview screen.

You can quickly refresh the preview without reloading the entire page.

🔧 Bug Fixes​

• Fixed an issue where the camera could clip into your own avatar during conversation with AI Avatars
• Fixed an issue where automatic movement from conversation with one AI Avatar to another AI Avatar might not reach the intended position
• Fixed an issue where the virtual stick could block the top buttons during mobile use
• Fixed an issue where the profile dialog would not scroll vertically
• Fixed an issue where the other party's VRM avatar would not display correctly when invited
• Fixed an issue where media display could occur based on incomplete URLs during realtime chat

"Speech Recognition Language" Setting Added​

Until now, the recognition language when performing voice input in Threedive AI was automatically determined by your browser's language settings (*unless explicitly specified in the AI Avatar). Therefore, when the language you actually speak and the browser language are different, speech might not be recognized properly.

With this update, Space users can now select and set their own spoken language. The configured content is saved and will continue to be used in the future.

You can configure it with the following operations.

1. Open the settings dialog from the gear ⚙ icon in the upper right corner of the 3D screen
2. Select the language to use in "Speech Recognition Language"

Please note the following points when configuring:

• If the AI Avatar's recognition language is fixed to a specific language, that fixed language takes priority.
• Please note that recognizable languages differ depending on your usage environment, so some languages may not function even if configured.

• Reviewed the order and hierarchy of the left-side menu
• Added rotation information fine-tuning feature
  • When placing AI Avatars/3D models/2D panels at anchor positions, you can now also change rotation information
  • Use this when you need to adjust the orientation of AI Avatars, etc. Basically, you do not need to change values other than Y Rotation

🐛 Bug Fixes​

• Fixed an issue where Spaces might not be displayed in the Space list when there are more than 100 created Spaces

3DGS File LoD Support (Lighter Rendering)​

When configuring 3D Gaussian Splatting (3DGS) files in Threedive AI Studio, you can now use the LoD (Level of Detail) option.

When this option is enabled, the following behavior occurs.

• Rendering processing may become lighter
  • Splats (elliptical plates) closer to the camera position will be displayed in more detail, while distant ones will be omitted. Especially for large 3DGS files, a reduction in processing load can be expected
• Loading time may become longer
  • Pre-calculation is performed after loading 3DGS files (excluding .rad files), so especially for large 3DGS files, loading time may be longer than usual

3DGS File Streaming Support (Faster Display Time for Spaces)​

We now support loading the .rad format as a 3DGS file.

If you convert existing 3DGS files to this format in advance, "streaming" of 3DGS becomes possible. When streaming is enabled, similar to streaming video playback like YouTube, files are gradually read while displaying, so display start becomes faster.

For more information about rad files, please see the following page

https://sparkjs.dev/docs/lod-getting-started/

🔧 Adjustments and Bug Fixes​
