ITEM CVI-I
Relevance Feasibility
Sound distortions (excluding distorted substitutions or distorted additions) 1.000 0.944
Distorted sound substitutions 1.000 0.889
Distorted sound additions (including intrusive schwa) 0.889 0.833
Increased sound distortions or distorted sound substitutions with increased utterance length or increased syllable/word articulatory complexity 0.944 0.944
Syllable segmentation within words > 1 syllable (Brief silent interval between syllables and/or inappropriate equalized stress across syllables) 1.000 1.000
Syllable segmentation across words in phrases/sentences (Increased inter-word intervals and/or inappropriate equalized stress across words) 0.944 0.944
Slow overall speech rate (apart from pauses for word retrieval and/or verbal formulation) 0.944 0.944
Lengthened vowel &/or consonant segments independent of overall slow speaking rate 0.944 0.889
RATE ONLY FOR AMRs (alternating motion rates, as in rapid repetition of “puh puh puh”): Slow and/or off-target (in place, manner, and/or voicing) 0= AMRs normal; 1= rare and mild, 2= frequent but mild; 3 = moderate, 4 = severe 1.000 1.000
RATE ONLY FOR SMRs (sequential motion rates, as in rapid repetition of “puh tuh kuh”): Slow (gaps within sequences), segmented (gaps between sequences), incorrectly sequenced, and/or off-target (in place, manner, and/or voicing) 0= SMRs normal; 1= any one of the listed features, 2= any two of the listed features; 3 = any three of the listed features, 4 = four of the listed features 1.000 1.000
One or both of the following: Consistently reduced words per breath group during phrase/sentence production relative to maximum vowel duration; reduced # of AMR repetitions per breath group in the absence of decreased respiratory capacity. Score on average number of syllables/repetitions per breath group across tasks: 0 = more than 7; 1= 6-7; 2 = 4-5; 3 = 3-4; 4 = 2 or less 0.944 0.944
Silent articulatory groping 1.000 1.000
Audible false starts/restarts or groping including sound repetitions, excluding fillers and unambiguous semantic false starts (e.g., spoo…fork) 1.000 0.944
Total 0.97 0.94
