Worksheets: Complexity Principles; Natural Phonological Tendencies; Lexical Properties, Markedness, SSP, Phonotactics and Facilitative Contexts

This resource page contains many examples of picture-and-word work sheets intended for use in speech-language pathology intervention.

The sheets were made in Microsoft Word, using copyright-free pictures from Microsoft Clip Art and Media and converted into portable document files (pdfs) with Adobe Acrobat.

The vocabulary represents (non-rhotic) Australian English pronunciation, and although most of the words and minimal pairs will 'work' in other dialects of English you may need to discard some. For example, pairs like saw-shore, and spa-star are minimal pairs in Australian English and in other non-rhotic varieties of English, but not in rhotic dialects such as Canadian, Irish, Scottish and most US 'Englishes'.

SLPs/SLTs and students are invited to use these worksheets and other resources when working with children with speech sound disorders. You are free to save them to your computer and to customize them to suit individual clients and to fit your service delivery model. Restrictions that apply to their use are stated in the copyright notice.

Systemic approach / 'Complexity approach'


When clinicians apply a traditional approach to treatment target selection their focus is on the phonetic level and the learnability of the individual sound. A systemic approach, or 'complexity approach' to treatment target selection, emphasises phonological restructuring of the sound system (Baker, 2009; Gierut, 2001; Williams, 2006b).

Expected or 'predicted' changes, due to generalisation, are system-wide. In a systemic approach, clinicians choose non-stimulable, later developing, phonetically more complex, and linguistically marked sounds, supported by least phonological knowledge. They may also take into account lexical properties in choosing treatment words.

Lexical Properties - Word Frequency & Density


We can consider lexical properties in choosing treatment words, selecting those that are ‘high frequency’ or those with ‘low neighbourhood density’.

High frequency words may be desirable treatment-words

High frequency words occur often, e.g., come, go, good, look, one. They are recognised faster by children than low frequency words.

Low neighbourhood density words may be desirable treatment-words

Low neighbourhood density words have 10 or fewer neighbours and are said to reside in sparse neighbourhoods.

Explanation

High neighbourhood density words are phonetically similar to many other words and have 11 or more neighbours. They are said to reside in dense neighbourhoods.

The words in a neighbourhood are based on one sound substitution (e.g., sat to pat or sat to sit), one sound deletion (e.g., sat to at) or one sound addition (e.g., sat to scat).

‘Bat’ is a high neighbourhood density word. It is in a dense neighbourhood of 40 according to the Washington University Speech Lab Neighborhood Database. The 39 neighbours are: back bad badge bag baht bait ban bang bash bass bast batch bath batteau batten batter battle beat bet bight bit boat boot bought bout brat but cat chat fat gnat hat mat pat rat sat tat that vat. ‘Ship’ is in a neighbourhood of 19 so has 18 neighbours: kip sheave shill zip sip nip shin dip gyp rip hip chip lip tip pip sheep shear shop shape.

Children recognise and repeat high-density words slower and less accurately than low-density words which have 10 or fewer neighbours. Also, children name high-density words more accurately than low-density words. This suggests that lexical processing in children entails a high-density disadvantage in recognition and a high-density advantage in production (Storkel, Armbruster & Hogan, 2006).

So, consider using words that are high frequency OR words that have low neighbourhood density (Storkel & Morrissette, 2002).

Implicational Relationships (Markedness) and Sonority


Relationships don't always work out, and implicational relationships are no exception. It is worthwhile, however, to experiment with target selection based on the marked properties of phonemes.

Markedness is a concept from the study of the sound systems of all natural languages. A marked feature in a language implies the necessary presence of another feature – hence 'implicational relationship'.

 


 

  • FRICATIVES are marked because they imply STOPS
  • VOICELESS STOPS are marked because they imply VOICED STOPS
  • AFFRICATES are marked because they imply FRICATIVES
  • CLUSTERS are marked because they imply SINGLETONS

Some research suggests targeting MARKED consonants in order to facilitate the acquisition of unmarked ones, or more precisely, targeting marked PROPERTIES of the system in order to facilitate acquisition of unmarked aspects of the system.

What this means in practice is that we can target fricatives in order to promote generalizations to fricatives and stops (it does not work in the other direction); we can target voiceless stops to facilitate generalization to voiceless and voiced stops; we can target affricates in the expectation that there will be generalization to affricates and fricatives; and we can target clusters to achieve generalisation to clusters and singletons.

Sonority Sequencing Principle (SSP)

Sonority is the amount of stricture or ‘sound’ in a consonant or vowel (Roca & Johnson, 1999). Steriade (1990) proposed a numerical sonority hierarchy: a list of phones, ordered according to degree of oral stricture and sound. Most sonorous are vowels (= 0), then glides (=1), liquids (= 2), nasals (= 3), voiced fricatives (= 4), voiceless fricatives (=5), voiced stops (=6) and finally the voiceless stops (=7) are least sonorant.

We prefer to articulate words with a rise and fall in sonority. For example, in 'tramp' we start with the least sonorous segment (voiceless stop /t/) then liquid /r/ with the vowel /æ/ at the peak, then the less sonorous nasal /m/, finally falling to the least sonorous voiceless stop /p/. This comes more ‘naturally’ to us than 'rtapm', for example, even though the segments are the same. This rise-then-fall tendency is called the sonority sequencing principle or SSP. 

Consonant clusters are more marked than singletons, but are some clusters more marked than others? One approach to classifying two-element consonant clusters according to markedness is to rank them according to their sonority difference score, using their numerical values from a sonority hierarchy (Ohala, 1999). For example, /kw/ (7 minus 1) has a sonority difference score of 6, whereas /fl/ (5 minus 2) scores 3. Clusters with SMALL sonority differences of 2, 3 or 4 may better promote generalised change to singletons and clusters. Gierut (1999), Gierut & Champion (2001), and Morrisette, Farris & Gierut (2006) provide evidence and target selection guidelines.

Pictures for the 3-element Clusters


Targeting the 3-element Clusters

Prior knowledge of the second element and the third element is required.

The 3-element consonant clusters, /spr/ /str/ /skr/ /spl/ and /skw/ should only be targeted if the child already has the relevant stop (/p/, /t/ or /k/) and the relevant liquid (/l/) or glide (/w/) present in his or her phonemic inventory. For example, if targeting /skw/ the child should have productive knowledge of /k/ and /w/, but does not need to have productive knowledge of /s/.

Targeting the 2-element Clusters

Prior knowledge of the first element and/or the second element is not required.

The 2-element clusters, /sm, /sn/, /fl/ etc. can be targeted irrespective of whether the child has previous knowledge of either or both of the two elements. For example, in targeting /sl/ the child may or may not have previous knowledge of /s/ and/or /l/.

Note that the adjuncts /sp/, /st/ and /sk/ are not subject to the sonority sequencing principle with respect to generalisation. What this means is, if you target adjuncts the child will learn to say them, but there will likely not be generalisation to the other adjuncts or to the clusters.

Iambs / Iambic feet

Some children who omit syllables only do so if the word is iambic (WS). For example they can say ‘monkey’ but not ‘giraffe’. Weak syllables tend not to be omitted word finally. Weak syllables are subject to omission, especially if they are word initial, as in “tomato” “potato” “computer” “banana” and “mosquito”. This pattern is exacerbated when an unstressed word is immediately before the iambic word, e.g.,“I saw a guitar” (WSWWS).

For carrier phrases, it is easier for the child to say the iambic word without omitting the weak (first) syllable if you make the phrase iambic (WSWSWS) ‘I saw a big guitar’, ‘I heard a loud guitar’, ‘I had a toy guitar’, ‘I want a new guitar’.

Phonological Tendencies and Trochees

camel rider

When working on extending the number of syllables a child can say, or in working on sequencing the syllables in polysyllabic words and word combinations, it can be helpful to start with trochaic sequences. This is because there is a natural tendency for children to find them easier to say. A trochaic foot, or trochee, has a strong syllable followed by a weak syllable.

In the following sets of pictures and words each image is associated with a sequence of two trochees (STRONG weak STRONG weak) like CAmelRIder (camel rider) andWAterMElo (watermelon).

As the child grows in confidence and can say a good selection of trochaic words, gradually introduce new long words that are not trochaic, e.g., alphabet, America and dinosaur.

Phonotactics - Final Consonants (Codas)


Final Consonant Deletion / Deletion of Coda

Most consonants are mastered first SIWI. The exceptions are velars and fricatives which are mastered first SFWF. English has a LOT of final consonants, the most prevalent of which are velars, fricatives and voiceless stops.In typical development, children produce codas (final consonants) more often after short (lax) vowels.

When working on eliminating Final Consonant Deletion choose words like bus, check, cop, rather than base, choke, keep where the vowel is long (tense).

At first, credit any final consonant, building on what the child already has in his or her inventory. If possible, select words with ‘favoured’ (in the language) final consonants: i.e., fricatives, velars and voiceless stops.

Phonological Tendencies and Reduplication


In working to eliminate reduplication capitalise on the natural phonological tendency for toddlers to produce /i/ as the second vowel ov a CVCV word or babble. Note also that alveolars tend to co-occur in the language with high front vowels. Choose, as therapy targets, words such as pretty, itty-bitty, daddy, tidy, pussy, messy, busy, easy funny, bunny, silly and billy.

Pictures & Words for Eliminating Reduplication

1-syllable words with Alveolars and High Front Vowels; 2-syllable words with alveolar + /i/

Spotty Snap

Use the 2-syllable words on the "spotty snap" sheets above to help children who find it difficult to produce >1 syllable (i.e. those who only produce monosyllables). Try /iː/ following a CVC word where both consonants are alveolars – Ted/teddy, etc. In extending this try to use words with a short vowel in the first syllable. Then try /iː/ following a CVC word where only the second consonant is an alveolar puss/pussy, etc.

Ted teddy, sun sunny, Dad Daddy, Sis Sissy, Nan Nanny, puss pussy, mess messy, fun funny, mouse mousie, goose goosie, kiss kissy, rat ratty, bird birdie, rain rainy, bud buddy; pretty muddy busy dizzy frilly silly; Spotty Snap Game (larger pictures on two pages); Spotty Snap Game (smaller pictures on one page); final and within word alveolar word lists


Backward Build-ups for teaching long words


Backward build-ups have long been used used in ESL and teaching (and in teaching children and adults other languages too). Velleman (2003) advocates backward build-ups as a therapy technique for multi-syllabic words, especially with children with CAS. You start with as much of the end of the word a child can say. This might even be ALL of the word except the first syllable.

Here are four examples.

  1. dictionary
    teach and strengthen "arry"
    THEN
    teach and strengthen "shun-arry"
    THEN
    teach and strengthen "dick-shun-arry"
    THEN
    modify the stress and timing (prosodic features)
    until you have dictionary
  2. California
    teach and strengthen "yuh"
    THEN
    teach and strengthen "forn-juh"
    THEN
    teach and strengthen "lee-forn-yuh"
    THEN
    teach and strengthen "callie-forn-yuh"
    THEN
    modify the stress and timing (prosodic features) until you have California

Successive Approximations (Progressive Approximations)


Successive Approximations (also called Progressive Approximations) involve a shaping technique in which the child is taught to use syllables he or she can pronounce in order to produce an intelligible but not-quite-perfect version (an approximation) of the target word or phrase. In the following example, Max, who was unable to produce /r/ was taught to say Leura Public as "Loowa Public".
