Protocol - Phonological Inventory
The “Sounds-in-Words” and “Sounds-in-Sentences” sections of the Goldman-Fristoe Test of Articulation, Third Edition (GFTA™-3), are interviewer-administered tests that measure the respondent's articulation of all-consonant and some vowel sounds of Standard American English. The interviewer shows pictures and provides verbal cues to elicit answers from the respondent that demonstrate the articulation of speech sounds.
The “Sounds-in-Words” and “Sounds-in-Sentences” sections are proprietary subtests of the Goldman-Fristoe Test of Articulation, Third Edition (GFTA™-3). Each subtest of the GFTA-3 is a part of the complete test and is not sold separately. For this assessment to be considered valid, the investigator should make sure that the respondent speaks English as a first language. Examiners should take care to take regional and cultural differences in the pronunciations of words into account and not unnecessarily mark these different pronunciations as errors.
Summary of the “Sounds-in-Words” Section of the Goldman-Fristoe Test of Articulation, Third Edition (GFTA™-3)
The “Sounds-in-Words” section of the Goldman-Fristoe Test of Articulation, Third Edition (GFTA™-3), uses pictures to elicit articulation of single words when the respondent is prompted by a visual and/or verbal cue. The “Sounds-in-Sentences” section is a sentence imitation task based on one story for younger children (ages 4:0 through 6:11) and a different one for ages 7:0 through 21:11. All consonants and the “r-colored” vowels are tested for accuracy, as quantified with a standard score. Other vowel errors can be observed but do not count toward the standard score.
Scoring Instructions: For both subtests (“Sounds-in-Words,” “Sounds-in-Sentences”), a phoneme inventory is constructed. The phoneme tables contain fields for word-initial, word-medial, and word-final positions. Separately for each subtest, the raw number of sounds in error is converted into a standard score and percentile. Norms are available separately for males and females.
Note that this test is designed to measure articulation accuracy of consonants and the r-colored vowels. It does not adequately characterize signs of motor speech disorders such as apraxia of speech or dysarthria. If concerns regarding motor speech disorders arise after obtaining a low GFTA-3 score, follow-up testing can be done using a motor speech exam or specially developed standardized tests. When administering the GFTA-3, some hints of motor speech disorders can be observed and used toward follow-up testing. Indicators for dysarthria are the following speech sound errors: pronouncing a “t” or “d” sound more like “n” and a “p” or “b” sound more like “m.” This shows weakness or stiffness in the articulatory muscles, as the person is not able to build enough air pressure inside the mouth to produce the popping sound. Indicators for apraxia of speech include lots of vowel errors, inconsistent productions of the same word, a consonant inventory that is far too small given the person’s age, and consonant deletions or saying the “h” sound instead of a consonant.

Personnel and Training Required
The Goldman-Fristoe Test of Articulation, Third Edition (GFTA™-3), can be administered by a trained research technician. Examiners should have training in phonetics and transcription using the International Phonetic Alphabet. The general qualification level B is described in more detail here: https://www.pearsonclinical.com/language/qualifications.html. Examiners should have formal training in the ethical administration, scoring, and interpretation of clinical assessments. Additionally, investigators are encouraged to have quality control procedures in place to maintain consistency across examiners.
The interviewer will need the picture plates, a copy of the response form, and the instruction manual and scoring instructions.
