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 communication system and method usable to facilitate communication between a hearing user and an assisted user. In particular, the system employs a wireless portable tablet or other portable electronic computing device linked to a captioning enabled phone as a remote interface for that phone, thereby providing an assisted user with more options, more freedom, and improved usability of the system.

Abstract: A method and system for providing captioned telephone service, the method comprising the steps of, initiating a first captioned telephone service call, during the first captioned telephone service call, creating a first set of captions using a call assistant, simultaneous with creating the first set of captions using a call assistant, creating a second set of captions using an automated speech recognition engine, comparing the first set of captions and the second set of captions using a scoring algorithm based on errors between the first and second sets of captions to generate a score for the second set of captions, in response to the score being within a predetermined threshold range, continuing the call using only the automated speech recognition engine to generate text and in response to the score being outside of the predetermined threshold range, continuing the call using a call assistant to generate captions.

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 of operating a captioned telephone call in which an assisted user's (AU's) captioned device is connected by a first line to a hearing user's (HU's) device and by a second line to a relay providing captioning for a conversation is disclosed. The method includes capturing an AU's voice signal via a microphone, transmitting the voice signal from the captioned device to the HU's device on the first line, obtaining a combined voice signal including both users' voice signals from the first line at the captioned device, cancelling the AU's voice signal from the combined signal to generate an independent HU voice signal, broadcasting the HU's voice signal via a speaker, transmitting the independent HU's voice signal to the relay, receiving captions at the captioned device from the relay corresponding to the HU's voice signal, and presenting the captions as text on a display screen.
