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 system for providing voice-to-text captioning service comprising a relay processor that receives voice messages generated by a hearing user during a call, the processor programmed to present the voice messages to a first call assistant, a call assistant device used by the first call assistant to generate call assistant generated text corresponding to the hearing user's voice messages, the processor further programmed to run automated voice-to-text transcription software to generate automated text corresponding to the hearing user's voice messages, use the call assistant generated text, the automated text and the hearing user's voice messages to train the voice-to-text transcription software to more accurately transcribe the hearing user's voice messages to text, determine when the accuracy exceeds an accuracy requirement threshold, during the call and prior to the automated text exceeding the accuracy requirement threshold, transmitting the call assistant generated text to the assisted user's device for display to the assisted user and subsequent to the automated text exceeding the accuracy requirement threshold, transmitting the automated text to the assisted user's device for display to the assisted user.

Abstract: A text-assisted telephony system for use by an assisted user while communicating with a hearing user via a hearing user's phone device. The system includes first and second assisted user's communication devices, each including a processor, a microphone, a speaker, a display and a communication component. One processor is programmed to establish a voice call with the hearing user's phone device. One processor is programmed to establish a communication link with the other processor. Each processor is programmed to generate an alert indicating when an incoming call is received and to enable an assisted user to answer the call and, upon one of the devices being used to answer a call, that device receiving text captions from a remote relay corresponding to a hearing user's voice signal and presenting the text captions to the assisted user via the device display.

Abstract: A captioning system comprising a processor and a memory having stored thereon software such that, when the software is executed by the one or more processors, the system generates text captions from speech data, including at least the following, receiving, from a hearing user's (HU's) device, an HU's speech data, generating, at the one or more hardware processors, first text captions from the speech data using a speech recognition algorithm, automatically determining, at the one or more processors, whether the generated first text captions meet a first accuracy threshold and when the first text captions meet the first accuracy threshold, sending the first text captions to an assisted user's (AU's) device for display, when the first text captions do not meet the first accuracy threshold, generating, at the one or more processors, second text captions from the speech data based on user input to the speech recognition algorithm from a call assistant and sending the second text captions to the AU's device for display.
