7 Hence, the task is to isolate aspects of communication which appear to be important in conversational speech perception for measurement as discrete variables.įirst, we need to look at the applicability of traditional speech perception tests in measuring aural rehabilitation outcomes.

3,5 Unfortunately, the transition from open-set tests of recognition of words in sentences to speech perception in the real world is too large to control all of the variables influencing intelligibility. Unrelated lists of sentences may underestimate a persons speech perception capabilities because the lists do not take advantage of the dynamic exchange of information and use of context and environment.

Several authors 5,6 recommend the development and use of speech perception tests which better estimate an individuals communicative competence in real-life situations. 4 While these testing conditions are reliable and easily standardized allowing for comparison and replication of procedures, they differ from true communication exchanges where sentences are not isolated events and recognition is not reliant solely on perceptual capabilities but rather on the ability to use the linguistic context and environmental cues. 3 Typically, in a test of sentence perception, the conditions are held constant, each stimulus sentence is presented only once, the listeners ability varies due to perceptual ability, and responses are scored as percent correct. One difficulty with traditional assessments of speech perception is that they do not reflect the dynamic nature of communication. Speech is interactive and based on the context of the linguistic environment (ie, the relationship between the preceding utterance and the target utterance). Communication, which often occurs in the form of sentences, is rarely devoid of external context.

Open-set tests of sentence perception still lack full external generalizability. 2 Tests of word perception increase the linguistic content, allowing the listener to use further speech cues and lexical knowledge to determine the identity of the word.įurthermore, the recognition of words in sentences depends on linguistic context and metalinguistic skillsboth of which are important to the perception of speech in conversations. While closed-set perception of nonsense syllables assesses the listeners acoustic perception, the tests require the listener only to listen for subtle differences between phonemes (eg, /aga/ vs /apa/) and do not require the organization of streams of information into recognizable words or sentences. It is hoped that these new measures may assist the identification of functional goals and the measurement of program benefit.Įxploring Speech Perception Tests One of the aims of speech perception testing is to provide some estimate of the level of difficulty that adults with a hearing impairment may have in daily communication. New measures of speech perception are now being developed, expanding the utility of speech perception testing through examination of the use of contextual effects and a measurement of meta-linguistic proficiency. In most cases, the results of rehabilitation are too subtle to be detected in gross measures of improvement in speech perception. Unfortunately, the utility of these measures in planning individualized rehabilitation programs or measuring aural rehabilitation program success is limited. Tests of speech perception have traditionally been used as global measures of performance, particularly in the areas of hearing aid comparison, hearing instrument success, and patient selection for cochlear implants.
