Speech Supplemented Word Prediction Program

描述（由申请人提供）：商用语音识别软件为许多身体有限制的人提供了一种重要的计算机访问方法。虽然这种访问方法对于具有正常语言的人来说是相当可靠的，但患有运动语言障碍（构音障碍）的人目前还不能可靠地使用这种技术。本研究的目的是为这些人提供一种独特的辅助设备访问方法，利用他们的语言。我们将通过继续开发语音辅助单词预测程序（SSWPP）来实现这一目标，该程序使患有音障碍的人能够利用他们的语言能力与个人电脑进行互动，重点是辅助写作。SSWPP的核心元素是与单词预测结合使用的定制语音识别软件。第一阶段开发的SSWPP的可行性结果令人兴奋。患有构音障碍的人在典型句子上平均节省了68%的按键次数。商业上可用的单词预测程序在同一文本上节省的按键次数不超过47%。第二阶段的设计活动包括改进语音识别引擎，开发优化的麦克风接口，将SSWPP集成到Microsoft Word中，以及开发用于面对面交流的语音到文本显示。残疾人士将对新的社会福利计划进行评估。语音辅助词预测程序是一种为残障人士提供的工具，他们也有理解语音的困难。这个工具使这些人能够使用他们的语言来减少向计算机输入文本所需的工作量，并更有效地进行口头交流。

DESCRIPTION (provided by applicant): Commercial speech recognition software offers many people with physical limitations an important computer access method. While this access method is reasonably reliable for people with typical speech, people with motor speech disorders (dysarthria) are presently not able to use this technology reliably. The purpose of this research is to provide these people with a unique assistive-device access method that utilizes their speech. We will accomplish this by continuing to develop a Speech Supplemented Word Prediction Program (SSWPP) that enables people with dysarthria to use their speech capabilities to interact with personal computers, with an emphasis on assisted writing. The central element of the SSWPP is custom speech-recognition software used in conjunction with word prediction. The feasibility results for the SSWPP developed during Phase 1 are exciting. The average keystroke savings achieved by people with dysarthria on typical sentences was 68%. Commercially available word prediction programs achieved no better than 47% keystroke savings on the same text. Phase 2 design activities include improving the speech recognition engine, developing an optimized microphone interface, integrating the SSWPP into Microsoft Word, and developing a speech-to-text display for use in face-to-face communication. People with disability will evaluate the new SSWPP. The Speech Supplemented Word Prediction Program is a tool for people with disability, who also have difficult to understand speech. This tool enables these people to use their speech to reduce the amount of work required to enter text into a computer and to communicate verbally more effectively.
