Automatic volume control of a voice signal provided to a captioning communication service
First Claim
1. A communication device comprising:
- a microphone configured to capture first sound and generate a near-end voice signal based on the first sound;
communication elements configured to receive a signal that includes a far-end voice signal obtained over a network and to direct an audio stream signal to a captioning communication system remote from the communication device, the audio stream signal based on the received signal; and
a computing system communicatively coupled to the microphone and the communication elements and configured to cause the communication device to perform operations, the operations comprising;
determine an activity of the received signal;
determine an activity of the near-end voice signal; and
automatically control a volume level of audio, which is based on the audio stream signal, produced by the captioning communication system based on the activity of the received signal and the activity of the near-end voice signal, the automatically controlling the volume level of the audio including reducing the volume level of the audio in response to the received signal being inactive and the near-end voice signal being active.

Abstract
Apparatuses and methods are disclosed for automatic volume control of an audio stream reproduced by a captioning communication service for use by a call assistant in generating a text transcription of a communication session between a hearing-impaired user and a far-end user. The automatic volume control automatically adjusts a volume of the audio stream reproduced by the captioning communication service responsive to a volume control command identifying which of the far-end voice signal and the near-end voice signal is active at a given time. The system further includes an echo modifier configured to add distortion to an echo portion of the far-end voice signal when generating the audio stream.

9. A method comprising:
-
determining an active talker situation responsive to comparing a near-end voice signal generated by a near-end communication device and a received signal based on a far-end voice signal derived from a far-end communication device; generating, at the near-end communication device, an audio stream signal based on the received signal; directing the audio stream signal to a captioning communication system remote from the near-end communication device; and automatically controlling a volume level of audio, which is based on the audio stream signal, produced by the captioning communication system based on the determined active talker situation, the automatically controlling the volume level of the audio including reducing the volume level of the audio in response to the determined active talker situation indicating that the received signal is inactive and the near-end voice signal is active. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A system comprising:
-
one or more non-transitory computer-readable media having instructions stored thereon; and one or more processors communicatively coupled to the one or more computer-readable media and configured to, in response to executing the instructions, cause the system to perform operations, the operations comprising; obtain, from a communication device remote from the system, an audio stream signal that is generated from a received signal that is received at the communication device over a network and that is based on a far-end voice signal generated by a far-end communication device; and produce audio based on the audio stream signal in which a volume level of the produced audio is based on activity of the received signal at the communication device and based on activity of a near-end signal generated by the communication device based on sound captured by a microphone of the communication device, wherein the volume level of the produced audio is reduced in response to the received signal being inactive and the near-end signal being active. - View Dependent Claims (20)
