The long term objective of this research in Phase I and Phase II is to develop a speaker-independent, voice-activated telephone interface for use by quadriplegics and others, with the innovative capability of handling speech produced by people who require ventilators. Specific objectives include: (1) collecting and analyzing "ventilator speech" produced by people with spinal cord injuries at different phases of rehabilitation; (2) modifying Emerson & Stern's existing SOLILOQUY R Voice Interface Software to handle breath-related interference and ignore non-speech interjections, without compromising SOLILOQUY's current speaker-independence; and (3) determining if an adequate telephone interface can be affixed to a halo orthotic. These objectives will be met by (1) recording telephone numbers spoken by patients at Sharp Hospital's Rehabilitation Center; (2) using a series of in-house software tools for speech analysis; (3) iteratively improving SOLILOQUY's microphone recognition algorithms and testing the results; (4) making similar changes to telephone-based algorithms; and (5) testing a cervical orthosis-mounted phone interface. Other voice-activated phones are speaker-dependent, requiring users to "re- train" the system every time their voice changes. No other system has SOLILOQUY's linguistic ability to ignore a non-speech sound by treating it as extraneous speech.

本研究第一阶段和第二阶段的长期目标是 开发一个独立于扬声器的声控电话界面， 由四肢瘫痪者和其他人创造， 需要演讲者的演讲。 具体目标 包括：（1）收集和分析 脊髓损伤患者在康复的不同阶段;（2） 修改艾默生和斯特恩现有的SOLILOQUY R语音接口软件 为了处理与呼吸相关的干扰并忽略非语音感叹词， 不影响SOLILOQUY目前的发言人独立性;以及（3） 确定是否可以将适当的电话接口固定到光环上 矫正器 这些目标将通过（1）记录电话号码 夏普医院康复中心的病人所说的话;（2）使用 一系列用于语音分析的内部软件工具;（3）迭代 改进SOLILOQUY的麦克风识别算法，并测试 结果;（4）对基于电话的算法进行类似的更改;以及（5） 测试颈椎矫正器上的手机接口。 其他声控电话是扬声器依赖的，需要用户“重新”， “训练”系统每次他们的声音变化。 没有其他系统 SOLILOQUY的语言能力，通过处理它来忽略非言语声音 无关的言语。
