Speech Perception Training: Advanced Scoring and Feedback Methods
- Conditions
- Hearing Loss
- Interventions
- Behavioral: Speech Recognition Training
- Registration Number
- NCT05012774
- Lead Sponsor
- SeeHear LLC
- 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.

Group Intervention Description Aim 3, Audiovisual Nonsense Word Training Speech Recognition 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. Aim 1, Sentence Training: Sentence Feedback Speech Recognition Training 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. Aim 3, Audiovisual Sentence Training Speech Recognition 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. Aim 1, Sentence Training: Word Feedback Speech Recognition Training 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. Aim 1, Sentence Training: Consonant Feedback Speech Recognition Training 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. Aim 2, Nonsense Word Training Speech Recognition Training Participants train to lipread nonsense words that name nonsense pictures. Participants receive pre- and post-training tests.
