Tongan Basic©

~ auditecinfo ~ Leave a comment

The Tongan Basic© consists of a word list for obtaining speech recognition threshold (SRT) and four lists of 50 words for speech discrimination. Additionally, the recording includes verbal patient instructions in Tongan. The lists are spoken by a male talker. Unlike English basic word lists, these word lists do not use a carrier phrase. A three-second interval is used between words.

This product includes a) audio recording, and b) printed word lists. This item does not include administrator instructions or normative data. It is assumed that purchasers of Auditec’s auditory tests are well trained in the use, purpose, and interpretation of basic tests.

WORD RECOGNITION TESTING, LIVE VOICE VS. RECORDED

~ auditecinfo ~ 1 Comment

Written by William F. Carver, Ph.D., FAAA, FASHA, CCC(A)ret.

You receive a referral from an audiologist.  An audiogram which includes a word recognition score is sent with the patient.  What can you tell from the word recognition score?  Nothing!   What list was used; W-22, NU-6, or PBK lists?  Did the audiologist use live voice, or was it from a recording?  Was it from a commercially available recording?  What is the articulation function (performance/intensity function) of the recording or of the audiologist’s voice? These variables can have a profound effect on  a word recognition score.

Presentations of cases (Grand Rounds) at conventions and meetings usually include an audiogram, SRT and word recognition scores…again what can you tell from the word recognition score?  If the presentation does not include information relative to how it was obtained with what materials, you have no real idea of the patient’s ability to discriminate speech.

To convey the crucial information about a person’s ability to communicate verbally, one must specify, not only the word recognition score, but must list: the list (i.e. W-22 or NU-6), the sensation level at which the test was administered, whether live voice or recorded.  If live voice, what is “normal?”  If from a recording, who’s recording (i.e. Auditec, dubbed from Technisonics, LAFO, QMass, etc.) ?

What variables control a word recognition score?  1.  The talker (the primary source of variation), 2. The presentation level, and 3. The list employed.

Word recognition (nee speech discrimination) is a slippery aspect of auditory tests.  Attempts have been made to standardize word recognition testing, but results have been disappointing.  Ideally, recorded tests that have been used throughout the area should be used.  And, ideally, one should not rely on a single score.  It has been shown that some sensory-neural patients will exhibit an articulation function that rises slowly and then curls over at higher levels.  Thus if one measures word recognition at a comparatively low level, it may be missed that a patient’s word recognition gets worse at higher levels.  A significant finding.

The point is, one should take the time to used recorded materials when testing for word recognition and ideally, especially in sensori-neural cases, obtain at least two measures at medium and high levels.

Adult word recognition lists like the NU-6 and W-22 and child word recognition lists like the PBK are available from Auditec, Inc.
