SmartSub: SmartSub that provides real-time speech translation

SmartSub SmartSub is a lightweight tool that provides real-time speech translation by integrating AI translation APIs with the Windows live caption feature. Features • System Integration Automatically calls the Windows live caption function, eliminating the need to open a separate subtitle window. After first use, system captions are hidden by default but can be re-enabled in settings. • Real-time Translation Supports real-time audio translation. By enabling the "Include microphone audio" option in Windows live caption, voice conversation translation can be achieved. • Clean Interface Adopts a Fluent UI design, consistent with the Windows system style, and supports automatic light/dark theme switching. • Translation Services Supports multiple translation engines, including Google Translate, OpenAI, and other API services. It is recommended to use LLM-based translation engines for handling incomplete sentences and context. • Floating Subtitles Provides a borderless, transparent floating window to display subtitles, suitable for gaming, video streaming, and live broadcasts. Users can adjust the window background, font size, color, opacity, and set the number of sentences displayed simultaneously. • Operation Control Supports window always-on-top, translation pause/resume functions, and allows one-click copying of subtitle text. • Record Management Saves original text and translation history, supporting export to CSV files. Displays recent record logs as cards to help understand context.
