听障人士无法感知自己的音高，因而难以控制音高。唱歌时，需要控制音高，以维持稳定的音调。为了解决这个问题，开发了一种触觉语音音高控制系统来帮助这些人唱歌。在之前的一项研究中，两名盲人受试者使用所提出的系统来控制他们的音高，其准确性与听力儿童相当。在本研究中，我们调查的本体感受音高控制和建议的语音音高控制系统对听力正常的人在附加噪声的条件下的效果。结果表明，没有触觉反馈的总平均偏差为405.6美分（SD：42.4），而有触觉反馈的总平均偏差为57.5美分（SD：12.2）。
Deafblind and hearing impaired persons cannot perceive their own voice pitch, and thus have difficulty controlling it. While singing, the voice pitch needs to be controlled to maintain a stable tone. To address this problem, a tactile voice pitch control system was developed to assist such people in singing. In a previous study, two deafblind subjects used the proposed system to control their voice pitch with accuracy comparable to that of the hearing children. In the present study, we investigate the proprioceptive pitch control and the effect of the proposed voice pitch control system on normal-hearing people under conditions of added noise. The results show that the total average mean deviation without tactile feedback is 405.6 cents (SD: 42.4), whereas, with tactile feedback, it is 57.5 cents (SD: 12.2).
