Strategies to Accommodate Reading (STAR) (STAR)
Strategies to Accommodate Reading (STAR): Using Assistive Technology to Support Reading by People With Aphasia.
People with aphasia often understand spoken utterances better than written sentences. They also benefit from having content appear in multiple rather than single modalities. Because text-to-speech (TTS) systems accommodate both of these functions, it provides an ideal basis for a reading intervention. TTS systems convert written text to provide both text and auditory information. Research about using TTS supports with people with aphasia has not extended beyond basic case studies and our studies of sentence level comprehension. Hence, no evidence exists about varying TTS features-such as speech output, speech rate, and text highlighting-known to benefit others with reading problems. Also, social acceptance of TTS is not well understood, even though it is critical to adoption and long-term use of the technology.
The purpose of this study is to evaluate various aspects of multimodality presentation of material through TTS systems used by people with aphasia. The immediate outcome of the proposed research will be evidence-based recommendations for selecting and adjusting TTS systems and features. This work will enable clinicians to maximize benefits for adults with varying aphasia profiles. We also will obtain initial evidence about the social validity and perceived value of TTS system use for this population.

Detailed Description
Experimental Procedures
- Phase 1: After completing the assessment session, phase one will include up to 4 sessions each lasting up to 90 minutes. Across the four sessions, the participants will listen to and/or read 36 passages ranging from 4 to 6 sentences each. Then, participants will answer 10 multiple choice questions related to the content of the passage. The researcher will provide comprehension support via written choice strategy for the multiple choice questions (e.g., written and spoken language, nonverbal supports such as pointing). Participants will read and/or listen to the stories via a computer. An example of these questions appears in Appendix G.
- Phase 2: After completing the assessment session, phase two will include 1 to 3 separate parts examining 3 different TTS features (e.g., speech presentation rate, text highlighting, speech production quality). Participants can choose to participate in 1 or more parts within this phase. For each part, participants will first listen to or view selected variations of a target feature and choose their preferred variation. For each study, participants will then complete five or four experimental sessions lasting up to 90 minutes each. Parts with up to five sessions (i.e., Part 1 and 2) will include features with more variations than those included in Part 3, which will include up to four sessions. Participants will read and/or listen to up to 12 reading passages in each session and answer multiple choice comprehension questions related to the content of the passage. At the conclusion of each session, participants will provide their opinion about the optimal targeted feature variation using rating forms and interview questions. Participants will read and/or listen to the passages via a computer.
- Phase 3: After completing the assessment session and any previous study phases, the participants will complete one 2-hour session. Participants will complete three activities: (1) education and system exploration guided by a member of the research team, (2) satisfaction and predicted use ratings of TTS systems, and (3) semi-structured interviews. Ratings of the TTS systems will be complete using Likert ratings scales (see Appendix H). Semi-structured interview questions will relate to rationales for system ratings and perceived application of TTS systems for functional use.
