语音在很多情况下是不合适的，限制了语音控制的使用。大多数无声语音文本输入系统不能在移动时使用，因为运动伪影。使用带有电容式触摸传感器的牙齿固定器，SilentSpeller可以跟踪舌头的运动，使用户可以通过拼写单词而无需发声。在一个1164个单词的字典中，SilentSpeller在离线孤立单词测试中实现了平均97%的字符准确率。步行对准确率影响不大；在行走时输入107个短语（97.5%）或坐着时输入107个短语（96.5%）的平均离线字符准确率大致相当。为了证明可扩展性，该系统对100个未见过的单词进行了测试，平均准确率为94%。7名参与者的实时文本输入速度平均为每分钟37个单词，准确率为87%。将静音拼写与当前的实践相比较，SilentSpeller可能是静音移动文本输入的可行选择。
Speech is inappropriate in many situations, limiting when voice control can be used. Most unvoiced speech text entry systems can not be used while on-the-go due to movement artifacts. Using a dental retainer with capacitive touch sensors, SilentSpeller tracks tongue movement, enabling users to type by spelling words without voicing. SilentSpeller achieves an average 97% character accuracy in offline isolated word testing on a 1164-word dictionary. Walking has little effect on accuracy; average offline character accuracy was roughly equivalent on 107 phrases entered while walking (97.5%) or seated (96.5%). To demonstrate extensibility, the system was tested on 100 unseen words, leading to an average 94% accuracy. Live text entry speeds for seven participants averaged 37 words per minute at 87% accuracy. Comparing silent spelling to current practice suggests that SilentSpeller may be a viable alternative for silent mobile text entry.
