Brief Summary:
The purpose of this two phase study is to evaluate comprehension by people with acquired brain injury. The phase 1 portion of the study will examine comprehension of narrative paragraphs under 3 conditions: (a) written text only, (b) auditory output only (i.e., synthetic speech - David voice) or combined written text and auditory output. The phase 2 portion of the study is to evaluate comprehension of sentences and paragraphs produced with computer generated (synthesized) speech and digitized natural speech after multiple exposures.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 60 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: During Study 1 participants will be exposed to three different conditions: (a) written text only, (b) auditory synthetic speech output only and (c) a combined condition (written and auditory output). During Study 2 participants will be provided repeated exposure to synthetic speech. Participants can participate in 1 or both studies with 1 study results not being dependent on the other study. .
Masking: None (Open Label)
Primary Purpose: Supportive Care
Official Title: Narrative Comprehension by People With Acquired Brain Injury
Actual Study Start Date : October 6, 2017
Estimated Primary Completion Date : October 6, 2018
Estimated Study Completion Date : October 6, 2018

Arm Intervention/treatment
Experimental: Comprehension Acquired Brain Injury
All participants will be exposed to 3 conditions: (a) written text, (b) auditory output (synthetic speech), and combined conditions for study 1. For study 2 participants will be repeatedly exposed to synthetic speech output to determine the influence on comprehension. Participants are not required to participate in both studies.
Behavioral: Comprehension Acquired Brain Injury
For study 1 participants will be exposed to 3 conditions as stated in previous descriptions and will last 1 to 2 sessions. Study 2 will begin with 1 session with the researcher lasting about 30 minutes. Then participants will be asked to complete practice at home for about 15 minutes each day for 2 weeks using a computer/iPad. Study 2 Post Testing and Maintenance Sessions 1 and 2: approximately 60 minutes per session.




Primary Outcome Measures :
  1. Comprehension Across Conditions (Study 1 of 2) [ Time Frame: Comprehension accuracy across conditions will be assessed over 1 to 2 days. ]
    Participants will answer 10 multiple choice questions regarding the information contained in each of the 12 stories presented in 3 conditions: (1) written text only (b) auditory output only and (c) combined written text and auditory output .

  2. Repeated Exposure to Digitized and Synthetic Speech (Study 2 of 2) [ Time Frame: 2 weeks ]
    Participants will answer 30 yes/no questions per session. Comprehension percentage accuracy will be measured over the course of 2 weeks


Secondary Outcome Measures :
  1. Comprehension Generalization [ Time Frame: measured 1 week and 4 weeks post termination of treatment ]
    Participants will listen to two stories presented in synthetic, computer generated speech and answer comprehension questions about the content of the stories to determine auditory comprehension accuracy

  2. Perceived Comprehension Accuracy [ Time Frame: measured 1 week and 4 weeks post termination of treatment ]
    Participants will rate the accuracy and ease of comprehension of the sentences from each condition using a 5 point Likert scale.
