INITIAL ASSESMENT PROTOCOL

The complete battery consists of 18 tests, but not all of them need to be administered.

We use an initial protocol, to which additional in-depth tests are added if necessary.

The following slides illustrate the methodology.

INITIAL ASSESMENT PROTOCOL

1. uditive discrimination (couple of word)

2. lexical comprehension (single words)

3. grammatical comprehension (sentences)

4. lexical production (single words)

5. grammatical production (repetition of words, non-words and sentences)

6. spontaneous narration (from pictures)

EXPRESSIVE TASKS

1. lexical production (single words)

2. grammatical production (repetition of words, non-words and sentences)

3. spontaneous narration (from pictures)

EXPRESSIVE TASKS

2. grammatical production (repetition of words, non-words and sentences)

3. spontaneous narration (from pictures)

LEXICAL PRODUCTION

What it assesses:

access to vocabulary and articulation

Task: naming ad repetition

Stimuli: drawings of everyday objects, clothing, means of transport, animals, fruit, colours or actions (77 for preschoolers; 67 for schoolers)

SCORING

Rules:

• the child has 10 seconds to answer

• after 5 consecutive wrong answers the test is terminated

Now, I will show you a picture and you will have to tell me what it is called.

2 points Correct naming and articulation on the first attempt.

1 point: Correct naming after repetition by the adult.

SCORING

0 points: Does not answer or repeat correctly, even after repetition by the examiner.

In each case, marks are awarded for correct articulation and phonetic errors are analysed.

CLINICAL INTERPRETATION OF FINDINGS

Possible deficits

Narrative skills encompass all linguistic skills: perceptual, articulatory, phonetic, phonological, expressive, lexical, grammatical, pragmatic, metalinguistic and social abilities. For this reason, narrative tests provide an accurate measure of a child's real communicative ability.

FINALLY: HOW TO MEASURE INTELLIGIBILITY?

Communicative effectiveness is based on the principles of quantity, quality, relevance and modality (Grice, 1975).

In verbal communication, quality and modality also depend on intelligibility, i.e. the degree to which a speech signal is understood.

HOW TO MEASURE INTELLIGIBILITY?

Intelligibility increases significantly between the ages of four and six years, so monitoring it is crucial for identifying early communication difficulties.

HOW TO MEASURE INTELLIGIBILITY?

The level of intelligibility is generally assigned according to the following parameters (Robertson, 1982):

 No observable alteration

 Slight difficulty, but still intelligible

HOW TO MEASURE INTELLIGIBILITY?

 Generally intelligible, but the listener must be very careful

 Often unintelligible, but can be understood with more careful repetition

 Mostly unintelligible

HOW TO MEASURE INTELLIGIBILITY?

But while there is substantial agreement on the instruments to be used for the assessment of lexical, formal and pragmatic aspects this is not the case with regard speech intelligibility

HOW TO MEASURE INTELLIGIBILITY?

In our clinical practice, after the repetition tests already mentioned from the BVL Battery, we propose an ad hoc test based on the inconsistency tests used in the CAS evaluation (Iuzzini-Siegel et al, 2017).

We use the inconsistency criterion

HOW TO MEASURE INTELLIGIBILITY?

inconsistency speech criterion is where the child produces words differently on each occasion they attempt a word.

A high degree of variability in verbal production indicates difficulty controlling the articulatory and phonological aspects of speech, which reduces intelligibility.

HOW TO MEASURE INTELLIGIBILITY?

Our task provided for the repetition of a list of 43 words, realized by choosing those present in the BVL battery, as they respect criteria of high frequency of use and high imaginability.

HOW TO MEASURE INTELLIGIBILITY?

These were varied by:

• length (bisyllabic, trisyllabic, quadrisyllabic)

• articulatory complexity

• lexical accent (altered or not altered)

• syllabic structure (reduced or not reduced).

HOW TO MEASURE INTELLIGIBILITY?

EXAMPLE OF ITALIAN WORD LIST

HOW TO MEASURE INTELLIGIBILITY?

Administer the list of target words three times, with a 10-minute break between each administration.

Elicit a spontaneous response by asking: “What is it?”.

If the child is having difficulty, you can provide assistance with double choice or imitation.

HOW TO MEASURE INTELLIGIBILITY?

Note

any help given to the child.

DC = double choice

I = imitation

Score: 0 = if all the answers are the same 1 = if the answers are different

HOW TO MEASURE INTELLIGIBILITY?

The inconsistency score is calculated by dividing the total score by the total number of words and multiplying by 100.

A total score of 10 or more (40%) is considered inconsistent.

HOW TO MEASURE INTELLIGIBILITY?

However, it is important to note that the results of this test can be influenced by the subjective interpretation of an inexperienced examiner.

For this reason, the use of AI-supported devices is being investigated.

HOW TO MEASURE INTELLIGIBILITY?

In emergency situations, an empirical method that is not scientifically based is often used.

Speech quality is checked to see if it is sufficient to activate speech devices based on large language models (LLM), such as Alexa, Siri or Cortana, which are used for specific languages.

HOW TO MEASURE INTELLIGIBILITY?

But after all, it is a first step towards making an objective assessment of speech intelligibility.

This is for the purpose of communication in everyday life.
