RANDOMIZED
PARALLEL
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Aim 1, Sentence Training: Sentence Feedback
In Aim 1, which is sentence lipreading training, the intervention compares the provision of three different types of feedback for lipreading.
This arm gives printed whole sentence feedback following an attempt to lipread each sentence.
Participants receive pre- and post-training tests.
Speech Recognition Training
Training for each training arm takes place over 10 sessions carried out at home. on the participant's own computer without experimenter direct supervision. Pre- and post-training tests are carried out under experimenter supervision.
Aim 1, Sentence Training: Word Feedback
In Aim 1, which is sentence lipreading training, the intervention compares the provision of three different types of feedback for lipreading.
This arm gives printed whole word feedback following an attempt to lipread each sentence. Word feedback is for correct words and words that are perceptually similar but incorrect responses.
Participants receive pre- and post-training tests.
Speech Recognition Training
Training for each training arm takes place over 10 sessions carried out at home. on the participant's own computer without experimenter direct supervision. Pre- and post-training tests are carried out under experimenter supervision.
Aim 1, Sentence Training: Consonant Feedback
In Aim 1, which is sentence lipreading training, the intervention compares the provision of three different types of feedback for lipreading.
This arm gives printed consonant word feedback following an attempt to lipread each sentence. Word feedback is for correct words, but only the consonants are given as feedback for words that are perceptually similar but incorrect responses.
Participants receive pre- and post-training tests.
Speech Recognition Training
Training for each training arm takes place over 10 sessions carried out at home. on the participant's own computer without experimenter direct supervision. Pre- and post-training tests are carried out under experimenter supervision.
Aim 1, Sentence Training: No Training Control
Participants receive only the pre- and post-training tests.
No interventions assigned to this group
Aim 2, Nonsense Word Training
Participants train to lipread nonsense words that name nonsense pictures. Participants receive pre- and post-training tests.
Speech Recognition Training
Training for each training arm takes place over 10 sessions carried out at home. on the participant's own computer without experimenter direct supervision. Pre- and post-training tests are carried out under experimenter supervision.
Aim 3, Audiovisual Nonsense Word Training
Participants train to recognize audiovisual spoken nonsense words that name nonsense pictures and are presented in speech-shaped noise. The paradigm is the same as in Aim 2.
Participants receive pre- and post-training tests.
Speech Recognition Training
Training for each training arm takes place over 10 sessions carried out at home. on the participant's own computer without experimenter direct supervision. Pre- and post-training tests are carried out under experimenter supervision.
Aim 3, Audiovisual Sentence Training
Participants receive the same training paradigm from Aim 1 with the most effective feedback type from Aim 1. But the sentences are audiovisual and in speech-shaped noise.
Participants receive pre- and post-training tests.
Speech Recognition Training
Training for each training arm takes place over 10 sessions carried out at home. on the participant's own computer without experimenter direct supervision. Pre- and post-training tests are carried out under experimenter supervision.
