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: An assisted user's (AU's) captioning device for assisting an AU during a call with a hearing user (HU) wherein the hearing user uses a HU's communication device, the captioning device comprising a display screen and a processor linked to the display screen, the processor programmed to perform the steps of upon receiving a call, automatically determining if the call is from one of a first set of HUs, upon determining that the call is from one of the first set of HUs, automatically initiating captioning and presenting captions of an HU voice signal during at least a portion of the call, and upon determining that the call is not from one of the first set of HUs, starting the call without captioning and providing an option to the AU to initiate captioning during the call.

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 system includes a first user device configured to perform captioning session operations, a call-assistant (CA) device remote from the first user device, and a remote relay server separate from the CA device. The relay server initiates a captioning process, receives, from the first user device, a request to initiate a captioning session, establishes the session, assigns the session to the CA, receives first audio data from the first user device derived from a second user device, directs the first audio data to the CA device, receives, from the CA device, second audio data related to the first audio data and derived from CA speech, accesses an ASR engine trained to the CA voice, generates captioned text including a transcription of the second audio data, generates screen information including the transcription, directs the screen information to the CA device, and directs the captioned text to the first user device.

Abstract: A method and system to transcribe communications the method comprising the steps of obtaining an audio message originating at a first device during a voice communication session between the first device and a second device, providing the audio message to a first speech recognition system to generate a first transcript of the audio message, directing the first transcript to the second device, in response to obtaining an indication that indicates a quality of the first transcript is below a quality threshold, using a second speech recognition system to generate a second transcript based on the audio message while continuing to provide the audio data to the first speech recognition system to generate the first transcript and, in response to occurrence of an event that indicates the second transcript is to be directed to the second device, directing the second transcript to the second device instead of directing the first transcript.
