Guankou Practice is an offline training app for xiangsheng fans, traditional performance learners, hosts, and anyone practicing speech fluency. You can organize guankou passages, tongue twisters, announcements, or your own routines into practice scripts, then improve familiarity through segmented prompting, covered recitation, timed reading, and practice records. The app requires no login, does not connect to the internet, and does not collect personal data. All scripts and practice records are stored only on your device. It is suitable for users who want long-term practice without relying on a complex online platform. Key features: 1. Local script library: organize common speech practice templates and create categories for guankou, tongue twisters, hosting scripts, and routines. 2. Segmented prompter: display text by sentence or paragraph with adjustable font size, line spacing, scroll speed, and dark mode. 3. Covered recitation: hide lines step by step, use keyword hints, and mark mistakes to move from reading to memorized delivery. 4. Rhythm timing: track section time, full-text time, target speaking pace, and completion counts for practice review. 5. Favorites and review: save frequently used scripts, mark difficult sections, and view recent practice, all stored fully offline.
