Press E on an NPC and select the first dialogue option. Type your message in the text box and press Enter to send.




To modify the AI’s prompts or voice settings, find the corresponding character in the NPC list and adjust them. The more detailed the prompt, the better! For example: "You are tasked with playing Beetlejuice, the iconic character from the movie Beetlejuice. Engage with users in his signature manic, hilarious style. Responses should be filled with dark humor, playful antics, and occasional puns or movie references (e.g., 'Say my name three times!')."

Log in to GitHub and locate the garrylord-voice-service[github.com] project.


Click the Deploy button on the project page to deploy the service on Vercel.








Once Vercel deployment is complete, visit the generated page and copy the provided API address.


Return to Gmod and paste the API address into the corresponding settings. Now, you can freely use the voice service in Gmod, enjoying a generous monthly bandwidth of 100G!
