Use this code with obs and Vtuber studio

You can use this code with OBS to show the subtitle and use Vtuber studio to show Live2D by following this guide.

1. Download OBS, Vtuber studio, EarTrumpet, VoiceMeeter banana(after you install VoiceMeeter banana you'll also need to restart your PC) and open VoiceVox.

2. For VoiceMeeter banana, we need to change voice output and voice input first.

   1. Open the Control Panel by pressing the Windows key and typing Control Panel. In the upper right corner, click on View by and select Large icon.

      

   2. Click on Sound, scroll down until you see VoiceMeeter Input, and then click on it. Finally, click Set Default.

      

   3. Click on Recording at the top, scroll down until you see VoiceMeeter Aux Output, click on it, and then click Set Default.

      

   4. The first time the program is opened, it would look like this.

      

   5. Click on each A1 to deselect them on all five panels. Similarly, do the same with B1. It should now look like this.

      

   6. On the upper right corner, click on A1 and select your speaker output (WDM is recommended).

      

   7. Now, click on A1 for all VIRTUAL INPUTS. However, for VOICEMEETER AUX, you'll also need to click on B1.

      

3. For Vtuber Studio.

   1. Open the settings by double-clicking on the screen and then click on the gear icon located on the left side.

      

   2. Scrolldown until you see Microphone Setting check Use microphone and select VoiceMeeter Output (VB-Audio VoiceMeeter VAIO) by clicking on the Microphone.

      

   3. Go to Model setting at the top left corner(a people icon with a gear). Scroll down until you see Mouth Open. Click on input and select or type VoiceVolumePlusMouthOpen.

      

   4. Optional: In Microphone Setting, I recommend setting Volume gain to 20 and everything else is set to 0.

4. For OBS, we'll add subtitles to display the text, and for Vtuber studio, we'll use it to show Live2D.

   1. To add a subtitle, press + in the source, select Text(GDI+), and name it as Subtitle.

      

   2. After adding the text source, a window will appear like this. You'll need to check Read from file and then click Browse.

      

   3. Navigate to subtitle.txt, which is located inside the text_log folder, and select it.

      

   4. Customize and configure the subtitle file according to your preferences, (For my recommendation, I suggest reducing the size of the text, setting Alignment to center and Verticle alignment to center, right-clicking on the text, navigating to Tranform and selecting Center Horizontally. Also, check Outline, set the outline size to 10-14, and change the outline color to black by clicking on Select color).

      

   5. To add Vtuber Studio, press + in the source, select Window Capture and name it as Live2D

      

   6. After adding the video source, a window will appear like this. Click on Window, select [VTube Studio.exe]: VTube Studio, on Capture Method choose Windows 10 (1903 and up), and then click OK.

      

   7. Right-click on the preview screen, choose Windowed Projector (Preview), and resize it as your desire.

      

5. Running the code, open EarTrumpet and scroll down to the bottom you'll see VoiceMeeter Input (VB-Audio VoiceMeeter VAIO), right click on Python 3.11.xx and click on change icon, select VoiceMeeter Aux Input (VB-Audio VoiceMeeter AUX VAIO).

   

6. Change your playback/output device by clicking on the speaker icon on the taskbar (or go to window setting -> System -> Sound -> Choose your output device). Select VoiceMeeter Aux Input (VB-Audio VoiceMeeter AUX VAIO) first and then selcet VoiceMeeter Input (VB-Audio VoiceMeeter VAIO) (we need to do this process to let Python recognize these playback devices).

   

7. In Vtuber Studio, open the settings, navigate to Microphone Setting and click on Reload.
