真實情境視聽多說話者語音理解測試的開發與評估

// Development and Evaluation of a Realistic Audio-Visual Multi-Talker Speech Comprehension Test

30名正常聽力成人中，我們用雙人自然對話混合安靜、0 dB、−5 dB雜訊，建立視聽理解測驗｜隨SNR下降，主觀努力↑、命中率↓、反應變慢，且轉頭更早更一致｜行為指標在控SNR後無法預測努力，但測驗對真實聽力情境敏感，可評估聽損與助聽器效益。

// We developed an audio‑visual speech comprehension test using spontaneous two‑talker conversations mixed with babble noise at three SNRs (Quiet, 0 dB, −5 dB) and measured performance in 30 normal‑hearing adults with a word‑monitoring task while recording self‑rated effort, hit rate, response time, and head turns. As SNR decreased, reported effort increased, hit rate dropped, and response times slowed; participants oriented toward the active talker (via head and eye movements) and did so earlier and more consistently in harder conditions. Behavioral measures did not predict effort once SNR was accounted for, but the test proved sensitive to realistic listening challenges and shows promise for assessing hearing loss and hearing‑device benefit.
