Internet Protocol Captioned Telephone Service is a service for people with hearing loss, allowing them to communicate effectively by having a human Communications Assistant transcribe the call and equipment that displays the transcription in near real time. The current state of the art for ASR is considered with regard to automating such service. Recent results on standard tests are examined and appropriate metrics for ASR performance in captioning are discussed. Possible paths for developing fully-automated telephone captioning services are examined and the effort involved is evaluated.
