  Many personal devices have transitioned from visual-controlled interfaces to
speech-controlled interfaces to reduce device costs and interactive friction.
This transition has been hastened by the increasing capabilities of
speech-controlled interfaces, e.g., Amazon Echo or Apple's Siri. A consequence
is that people who are deaf or hard of hearing (DHH) may be unable to use these
speech-controlled devices. We show that deaf speech has a high error rate
compared to hearing speech, in commercial speech-controlled interfaces. Deaf
speech had approximately a 78% word error rate (WER) compared to a hearing
speech 18% WER. Our findings show that current speech-controlled interfaces are
not usable by deaf and hard of hearing people. Therefore, it might be wise to
pursue other methods for deaf persons to deliver natural commands to computers.
