  • Abstract
    The speech intelligibility in noise of three different digital speech coding algorithms was investigated at the standard audio bandwidth of 300 to 3400 Hz and a developmental bandwidth of 100-6000 Hz. Speech intelligibility was measured using a standardized instrument, the Modified Rhyme Test (MRT). Performance was investigated at three different levels of an acoustic noise environment. This report presents results, discussion, conclusions and recommendations for further research.
