Abstract:
Speech input systems could not work well in noisy environment, and their usage often makes a leakage of information. To avoid these problems, this paper proposes a concept of Silent Voice Elements, called sivels for short, and a novel articulators-operated text input method with sivels. Sivels are easy-to-recognized phonemes of soft whisper in their tissue-conducted vibration signals. The selection of sivels is a combinational optimization problem which is solved by using a heuristic search algorithm. Encoding text with sivels similarly to Morse code, one can input text accurately by speaking corresponding sivels. Experimental results demonstrate that our method selects a set of sivels with perfect recognizability, and the proposed sivel-based text input also gives an performance with sufficient efficiency.
