Speech recognition in noise is an important aspect of human communication. Persons with similar degree of hearing level may have different recognition performance when they hear speech in noisy environment. Speech-in-noise test would be used to access the recognition performance under noisy conditions that are representative of real world. The current study is to construct an open-set sentence bank intended to serve as the target stimuli for speech-in-noise test which targets for persons aged at 6 to adulthoods with different hearing levels.

Each sentence will be 7 syllables in length on average and be kept at below 10 syllables in this study, so that the test items should be short and easy to repeat, challenging the hearing abilities of the individuals rather than the cognitive abilities. The sentences, containing lexical words that are frequently used in daily life by both persons with normal hearing and hearing impairment, will be constructed based on the basic sentence syntax in Cantonese Chinese.

Declarative sentence is selected as the target type of sentence stimuli because declarative sentence is easy to repeat without the needs of imitating the complex intonation required in other sentence types such as imperative or exclamation sentences.. The sentences are constructed based on five basic sentence structure including subject-predicate structure, predicate-object structure, predicate-complement structure, modifier-head structure and union structure. A sentence bank with 150 sentences are constructed for this study. The lexical words in the sentences are mainly selected from a corpus of word suggested by parents and teachers of hearing-impaired individuals from a survey done in 2003 by the second author of the study.

The sentence bank fulfills the validation needs in the development stage. Content-related evidence of validity of sentences would further be sought by expert consultation and by psychometric evaluation in the next development stage.
