Abstract: A call captioning system for captioning a hearing user's (HU's) voice signal during an ongoing call with an assisted user (AU) includes: an AU communication device with a display screen and a caption service activation feature, and a first processor programmed to, during an ongoing call, receive the HU's voice signal. Prior to activating the caption service via the activation feature, the processor uses an automated speech recognition (ASR) engine to generate HU voice signal captions, detect errors in the HU voice signal captions, use the errors to train the ASR software to the HU's voice signal to increase accuracy of the HU captions generated by the ASR engine; and store the trained ASR engine for subsequent use. Upon activating the caption service during the ongoing call, the processor uses the trained ASR engine to generate HU voice signal captions and present them to the AU via the display screen.

Abstract: A relay for captioning a hearing user's (HU's) voice signal during a phone call between an HU and a hearing assisted user (AU), the HU using an HU device and the AU using an AU device where the HU voice signal is transmitted from the HU device to the AU device, the relay comprising a display screen, a processor linked to the display and programmed to perform the steps of receiving the HU voice signal from the AU device, transmitting the HU voice signal to a remote automatic speech recognition (ASR) server running ASR software that converts the HU voice signal to ASR generated text, the remote ASR server located at a remote location from the relay, receiving the ASR generated text from the ASR server, present the ASR generated text for viewing by a call assistant (CA) via the display and transmitting the ASR generated text to the AU device.

Abstract: A system and method for facilitating communication between an assisted user (AU) and a hearing user (HU) includes receiving an HU voice signal as the AU and HU participate in a call using AU and HU communication devices, transcribing HU voice signal segments into verbatim caption segments, processing each verbatim caption segment to identify an intended communication (IC) intended by the HU upon uttering an associated one of the HU voice signal segments, for at least a portion of the HU voice signal segments (i) using an associated IC to generate an enhanced caption different than the associated verbatim caption, (ii) for each of a first subset of the HU voice signal segments, presenting the verbatim captions via the AU communication device display for consumption, and (iii) for each of a second subset of the HU voice signal segments, presenting enhanced captions via the AU communication device display for consumption.

Abstract: A captioning relay for captioning hearing user (HU) voice signals comprising a plurality of separate captioning resources and a captioning administrator module that receives HU voice signal segments corresponding to a plurality of separate ongoing calls between HUs and AUs and provides the voice signal segments in a first in, first out order to the captioning resources, the administrator module providing each voice signal segment from each call to any one of the captioning resources to be captioned without regard to which captioning resource captioned prior voice signal segments generated during the call and, the administrator module further receiving caption segments back from the captioning resources and providing those captioning segments to AU devices associated with the calls that generated corresponding HU voice signal segments, and wherein the number of captioning resources is less than the number of ongoing calls.

Abstract: A method for maintaining contact information in a hearing impaired assisted user's communication device includes the steps of (a) providing a web site for altering assisted user contact information, (b) linking a proxy device to the web site, (c) receiving an identifier associated with the assisted user's device via the proxy device, (d) identifying an assisted user's device via the received identifier, (e) enabling the proxy device to be used to modify contact information for the assisted user associated with the received identifier, (f) starting a timer to time out a sync timeout period, (g) during the sync timeout period, receiving an indication via the assisted user's device confirming a desire to update the assisted user's contact information, (h) updating the assisted user's contact information, and (i) at the end of the timeout period, ceasing an indication that updated data is ready to be used from the assisted user's device.

Abstract: A method to transcribe communications during a voice communication session between first and second devices includes obtaining an audio message originating at the first device. Upon initiating a captioning session, the message is provided to an automated speech recognition system to generate a first caption set for at least some of the message without any captioning assistance from a call assistant. The first caption set is made available to the second device for presentation on a display screen. In response to obtaining a first indication via the second device to change the captioning process, the audio message is provided to a second speech recognition system to generate a second caption set based on at least some of the message, where a call assistant performs error corrections to generate the second caption set. The second caption set then is made available to the second device for presentation on the display screen.

Abstract: A method includes obtaining a hearing user's (HU's) (first) voice signal including speech from a first device during a communication session between first and second devices, the session configured for verbal communication. The method also includes obtaining a first text string that is a transcription of the first voice signal via a first automatic speech recognition engine using the first voice signal, obtaining a second text string that is a transcription of the first voice signal via input obtained from a device associated with a call assistant, generating an output text string from the first and second text strings that includes one or more words from each of the first and second text strings, and providing the output text string as a transcription of the HU's voice signal for presentation during the session substantially concurrently with the presentation of the HU's voice signal by the second device.
