Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: In Aim 1, which is sentence lipreading training, the intervention compares the provision of three different types of feedback for lipreading. The three types are consonant-level, word-level, or sentence-level feedback. A no-training wait-list control is included.

In Aim 2, novel word training, the intervention has one arm in which novel word learning via lipreading the words is supported by allowing the participants to read the consonants in the novel words before lipreading them.

In Aim 3, the most effective feedback with sentence training will be compared with novel word training using training stimuli that are audiovisual speech in speech-shaped noise.

The interventions are all delivered individually via the web. Finally, all pre- and post-training results will be compared across groups including the wait-list controls.
Primary purpose: TREATMENT

Brief summary: The purpose of the study is to assess training of visual speech (lipreading) and audiovisual (lipreading plus auditory) speech as a rehabilitation strategy for hearing loss in adults.

Detailed description: It is hypothesized that training that improves lipreading in older adults can carry over to untrained lipreading materials and to audiovisual speech recognition in noise. Participants receive pre- and post-training tests of speech recognition with visual-only, auditory-only, and audiovisual spoken sentences and isolated words. During pre- and post-training tests, they carry out forced choice identification of lipread consonants. Participants who are assigned to a training arm train on lipreading isolated sentences (Aim 1) or on learning via lipreading sets of isolated nonsense words (Aim 2). Depending on the outcomes of Aims 1 and 2, in Aim 3, new participants receive audiovisual training with conditions from Aims 1 and 2.
