multimodal chinese text entry with speech and keypad on mobile devices
Chinese text entry is challenging on mobile devices which rely on keypad input. Entering one character may require many key presses. This paper proposes a multimodal text entry technique for Chinese. In this method, Chinese user can enter Chinese text by simultaneously using the simplified phonemic input method named Jianpin with keypad and speech utterance. The key of the technique is a multimodal fusion algorithm, which synchronizes speech and keypad input and fuses redundant information from two modalities to get the best candidate. A preliminary evaluation shows that users appreciate this technique and it could reduce key presses and enhance the input efficiency.
