CaptionCall Certified to Provide IP CTS Using Automatic Speech Recognition

On August 31, 2021, the FCC granted conditional certification to CaptionCall to provide Internet Protocol Captioned Telephone Service (IP CTS) using automatic speech recognition (ASR) in addition to its existing communications assistant-based IP CTS.  CaptionCall will introduce ASR-based IP CTS in overflow situations when a communications assistant is not available.  The ASR platform supports the display of captions on CaptionCall phones and other devices running the CaptionCall application.
