About

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.

Full 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.

138 participants in 7 patient groups

Aim 1, Sentence Training: Sentence Feedback

Experimental group

Description:

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.

Treatment:

Behavioral: Speech Recognition Training

Aim 1, Sentence Training: Word Feedback

Experimental group

Description:

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.

Treatment:

Behavioral: Speech Recognition Training

Aim 1, Sentence Training: Consonant Feedback

Experimental group

Description:

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.

Treatment:

Behavioral: Speech Recognition Training

Aim 1, Sentence Training: No Training Control

No Intervention group

Description:

Participants receive only the pre- and post-training tests.

Aim 2, Nonsense Word Training

Experimental group

Description:

Participants train to lipread nonsense words that name nonsense pictures. Participants receive pre- and post-training tests.

Treatment:

Behavioral: Speech Recognition Training

Aim 3, Audiovisual Nonsense Word Training

Experimental group

Description:

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.

Treatment:

Behavioral: Speech Recognition Training

Aim 3, Audiovisual Sentence Training

Experimental group

Description:

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.

Treatment:

Behavioral: Speech Recognition Training
