Speakers possess a natural capacity for lip reading; analogous to this, there may be an intuitive ability to "tongue-read." Although the ability of untrained participants to perceive aspects of the speech signal has been explored for some visual representations of the vocal tract (e.g. talking heads), it is not yet known to what extent there is a natural ability to interpret speech information presented through two clinical phonetic tools: EPG and ultrasound. This study aimed to determine whether there is any intuitive ability to interpret the images produced by these systems, and to determine whether one tool is more conducive to this than the other. Twenty adults viewed real-time and slow motion EPG and ultrasound silent movies of 10 different linguo-palatal consonants and 4 vowels. Participants selected which segment they perceived from four forced-choice options. Overall, participants scored above chance in the EPG and ultrasound conditions, suggesting that these images can be interpreted intuitively to some degree. This was the case for consonants in both the conditions and for vowels in the EPG condition.
说话者具备自然的唇读能力；与此类似，可能存在一种直观的“舌读”能力。尽管针对声道的某些视觉表现形式（如会说话的头像），已对未经训练的参与者感知语音信号各方面的能力进行了探索，但对于通过两种临床语音工具（电子腭图和超声波）呈现的语音信息，人们在多大程度上具备自然的解读能力尚不清楚。本研究旨在确定是否存在解读这些系统所生成图像的直观能力，并确定一种工具是否比另一种工具更有助于此。20名成年人观看了10个不同舌腭辅音和4个元音的实时及慢动作电子腭图和超声波无声影片。参与者从四个强制选择选项中选出他们所感知到的片段。总体而言，参与者在电子腭图和超声波条件下的得分高于随机水平，这表明这些图像在一定程度上可以被直观解读。两种条件下的辅音以及电子腭图条件下的元音皆是如此。
