When you need to learn how a Chinese character is written, the answer should be easy to find. Open Baba Chinese Writing, hold the microphone button, and ask for a character in Chinese—for example, “晴朗的朗字怎么写”. Release the button to see the character’s pinyin, writing grid, and animated stroke order. Baba Chinese Writing keeps one everyday task simple: ask for a character and clearly see how it is written. KEY FEATURES • Ask in Chinese by voice Hold to speak and release when finished. The app identifies the character you want to learn from a spoken Chinese phrase, without keyboard input. • Pinyin and writing grids Each character appears on its own card with tone-marked pinyin and a clear grid for understanding structure and proportions. • Animated stroke order Watch the character written one stroke at a time in the correct order, with progress shown during playback. • Tap to replay Tap any character card whenever you want to watch its writing animation again. • Learn up to six characters at once Study a single character or a short word. Card sizes and layouts adapt automatically to the number of results. • Designed for iPhone and iPad The practice area adapts to portrait, landscape, and different screen sizes. • Chinese and English interface The app follows your device language on first launch. You can switch the interface language at any time from Help. Voice character lookup always recognizes spoken Chinese. • Built-in learning resources Pinyin and stroke-animation resources are included with the app, so no online character library needs to be downloaded during use. • Focused and uncluttered No account, no social features, and no unnecessary steps between your question and the writing animation. TIP Speech recognition availability may depend on system support and network conditions. For the best results, clearly ask for the target character in Chinese, such as “晴朗怎么写” or “晴朗的朗字怎么写”.
