The NTID speech recognition test: NSRT(®)

Area of Science:

• Audiology
• Speech-Language Pathology
• Hearing Science

Background:

• Speech recognition testing is crucial for diagnosing hearing loss.
• Existing speech recognition tests may have limitations in efficiency and scope.
• The National- শব্দ Recognition Test (NSRT) aims to improve speech recognition assessment.

Purpose of the Study:

• To expand the item pool for the National- শব্দ Recognition Test (NSRT).
• To evaluate the performance and effectiveness of the NSRT adaptive testing software.
• To collect and analyze data for improving speech recognition measures.

Main Methods:

• Adults with mild to moderately severe hearing loss (N=70) completed pure-tone tests, W-22, QuickSIN, and new NSRT items.
• Participants underwent NSRT adaptive tests in quiet and noisy conditions.
• New NSRT items were analyzed using Rasch scaling; adaptive test performance was correlated with other measures.

Main Results:

• The addition of 323 new NSRT items successfully expanded the item pool, more than doubling its size.
• The NSRT demonstrated high reliability coefficients.
• Moderate correlations were found between NSRT performance and pure-tone thresholds (PTA, HFPTA) and other speech recognition measures (W-22, QuickSIN, SRT).

Conclusions:

• The adaptive NSRT is an efficient and effective tool for measuring speech recognition.
• The NSRT provides valid and reliable data on speech perception abilities.
• Expansion of the NSRT item pool enhances its utility in audiological assessments.
