Articulation index transfer functions for 'DANTALE' (200 monosyllabic words)

Area of Science:

• Audiology
• Speech Science
• Linguistics

Background:

• Speech recognition testing is crucial for audiological assessments.
• Standardized speech tests are needed for diverse languages like Danish.
• Articulation Index (AI) provides a framework for evaluating speech intelligibility.

Purpose of the Study:

• To develop Articulation Index (AI) transfer functions for the Danish DANTALE speech test.
• To compare the difficulty of DANTALE with other speech recognition measures.
• To evaluate the impact of different scoring methods on speech test performance.

Main Methods:

• Development of AI transfer functions for 200 monosyllabic words in the DANTALE test.
• Implementation of three distinct scoring methods.
• Comparative analysis against rhyme tests, unfamiliar sentences, and 256 phonetically balanced (PB) words.

Main Results:

• AI transfer functions were successfully established for the DANTALE test.
• DANTALE, when scored by word, demonstrated greater difficulty for speech recognition.
• The Danish DANTALE test presented a higher challenge than rhyme tests, unfamiliar sentences, and PB word lists.

Conclusions:

• The DANTALE speech test, with its AI transfer functions, offers a valuable tool for Danish speech audiometry.
• Word scoring of DANTALE highlights its rigorous nature compared to other speech tests.
• This research contributes to the development of language-specific speech recognition measures.
