对于身体残疾的人来说，语音识别可以是一个强大的工具，这些残疾阻碍了他们使用传统输入设备的能力。最先进的语音识别系统通常同时提供数据输入和光标控制机制，但研究人员仍在继续研究改善这些交互的方法。许多研究人员正在研究改进使语音识别成为可能的底层技术的方法，其他研究人员则专注于了解用户使用面向听写的应用程序所遇到的困难，但很少有研究人员调查基于语音的光标控制所涉及的问题。在这篇文章中，我们描述了一项研究，该研究调查了基于标准语音的光标控制机制的两种变体的有效性。一种使用标准鼠标光标，而另一种则提供预测性光标，旨在帮助用户弥补通常与语音识别相关的延迟。正如预期的那样，较大的目标和较短的距离会导致较短的目标选择时间，而较大的目标也会导致较少的错误。尽管标准光标和预测光标之间没有区别，但与语音输入相关的延迟、光标移动的速度和可以可靠选择的目标的最小尺寸之间的关系出现了，这可以指导类似基于语音的光标控制机制的应用以及未来的研究。
Speech recognition can be a powerful tool for individuals with physical disabilities that hinder their ability to use traditional input devices. State-of-the-art speech recognition systems typically provide mechanisms for both data entry and cursor control, but the researchers continue to investigate methods of improving these interactions. Numerous researchers are investigating methods to improve the underlying technologies that make speech recognition possible and others focus on understanding the difficulties users experience using dictation-oriented applications, but few researchers have investigated the issues involved in speech-based cursor control. In this article, we describe a study that investigates the efficacy of two variations of a standard speech-based cursor control mechanism. One employs the standard mouse cursor while the second provides a predictive cursor designed to help users compensate for the delays often associated with speech recognition. As expected, larger targets and shorter distances resulted in shorter target selection times while larger targets also resulted in fewer errors. Although there were no differences between the standard and predictive cursors, a relationship between the delays associated with spoken input, the speed at which the cursor moves, and the minimum size for targets that can be reliably selected emerged that can guide the application of similar speech-based cursor control mechanisms as well as future research.
