Existing voice-based interfaces have limited support for text editing, especially when seeing the text is difficult, e.g., while walking or cooking. This research develops voice interaction techniques for eyes-free text editing. First, with a Wizard-of-Oz study, we identified two primary user strategies: using commands, e.g., “<scps>replace</scps> go with goes ” and re-dictating over an erroneous portion, e.g., correcting “he go there” by saying “he goes there.” To support these user strategies with an actual system implementation, we developed two eyes-free voice interaction techniques, Commanding and Re-dictation , and evaluated them with a controlled experiment. Results showed that while Re-dictation performs significantly better for more semantically complex edits, Commanding is more suitable for making one-word edits, especially deletions. We developed VoiceRev to combine both the techniques in the same interface and evaluated it with realistic tasks. Results showed improved usability of the combined techniques over either of the two techniques used individually.

指挥和重新听写

现有的基于语音的界面对文本编辑的支持有限，尤其是当看见文本很困难，例如，在走路或做饭时。这项研究开发了用于免视文本编辑的语音交互技术。首先，通过绿野仙踪研究，我们确定了两种主要的用户策略：使用命令，例如“<scps>replace</scps>走和去”并重新口述错误的部分，例如，通过说“他去那里”来纠正“他去那里”。为了通过实际的系统实现来支持这些用户策略，我们开发了两种无眼语音交互技术，指挥和复述，并通过对照实验对其进行评估。结果表明，虽然 Re-dictation 对于语义更复杂的编辑表现明显更好，但 Commanding 更适合进行单词编辑，尤其是删除。我们开发了VoiceRev将这两种技术结合在同一个界面中，并通过实际任务对其进行评估。结果表明，组合技术的可用性优于单独使用的两种技术中的任何一种。
