“…A set of novel techniques and recipe configurations were proposed to learn both speech impairment severity and speaker-identity when constructing and personalizing these systems. In contrast, prior researches mainly focused on using speaker-identity only in speaker-dependent data augmentation [7,9,13,14,18,27] and speaker adapted or dependent ASR system development [1,3,4,7,11,13,19,22,23,25,[31][32][33]. Very limited prior researches utilized speech impairment severity information [2,11,25,[34][35][36].…”
