Speech Sound Disorder SSD overview

Speech Sound Disorder (SSD) - Overview

  • Definition of Speech Sound Disorder (SSD): SSDs refer to difficulties in producing speech sounds that can affect a child's ability to communicate clearly.

Analyzing Data for SSD Diagnosis

  • Data Collection: Important to analyze data collected from various assessments to determine presence and type of SSD.

    • Components of Data Collection:

    • Case history

    • Child's progression with Oral Motor Assessment (OMA)

    • Single word speech assessment

    • Connected speech samples

  • Error Analysis: Focus on identifying errors or mismatches in speech, particularly in multilingual children.

    • Mismatches: May arise from natural aspects of multilingualism, such as cross-linguistic transfer.

Key Considerations in Assessment

  • Phonological Patterns:

    • Explore processes or patterns in speech errors; both terms refer to the same concept.

    • Assess for phoneme collapse.

  • Disfluency Evaluation:

    • Percentage of consonants correct

    • Consistency of errors

    • Stimulability for certain sounds

    • Achievability of producing longer words (syllable count)

  • Intelligibility: Assess the overall clarity and the impact on activity participation, considering:

    • Child's age

    • Languages spoken

Types of Speech Sound Disorders (SSD)

  • SSD assessment informs intervention selection based on:

    • Nature of the SSD

    • Required intervention approach

Intervention Approaches for Different Types of SSD

  • Phonological Impairment: Characterized by pattern-based speech errors.

    • Intervention Focus: Target patterns rather than individual sounds (e.g., fronting, weak syllable deletion).

    • Goal Example: Reducing the phonological process of fronting in speech.

  • Inconsistent Speech Disorder: Focus on improving consistency in speech productions.

    • Example Activity: Using Core Vocabulary interventions to promote consistent production of designated words.

  • Articulation Impairment: Focuses on the correct production of specific sounds.

    • Goal: Teach correct articulatory placement (e.g., where to position the tongue).

  • Childhood Apraxia of Speech (CAS): Focus on improving core difficulties, including:

    • Accuracy of speech sounds

    • Consistent transitions between sounds and syllables

    • Prosody and stress (strong/weak patterns)

  • Childhood Dysarthria: Target different speech subsystems separately.

    • Goals may include:

    • Breath control

    • Voice sustaining for speech

    • Articulatory precision and accuracy, often using principles of motor learning.

Intervention Framework and Strategies

  • Differentiating between approaches based on the SSD type

    • Focus on identifying the specific challenges and developing tailored interventions.

Minimal Pairs Approach

  • Definition: A method used in therapy to illustrate the difference between two sounds (e.g. "key" vs. "tea").

  • Versions of Minimal Pairs:

    • Meaningful Minimal Pairs:

    • For stimulable sounds: Introduces picture cards and guides the child in recognizing sounds.

    • Perception-Production Minimal Pairs:

    • For non-stimulable sounds: Focuses on perception first, followed by production training.

Implementation Steps for Minimal Pairs Approach

  1. Familiarization:

    • Introduce minimal pair picture cards to ensure understanding of words.

  2. Listening and Pointing:

    • Child listens to the target word and points to the correct picture.

  3. Production Phase:

    • Child responds by stating the word and instructing which card to pick.

    • Address communication breakdowns if necessary.

Teaching Moments

  • Definition: Points of interaction where the speech pathologist prompts a response from the child, involving:

    • Antecedents: Setting up the context (e.g., presenting cards).

    • Child’s Response: Actions taken by the child, such as pointing or verbalizing.

    • Consequent Feedback: Providing encouragement or corrections based on the child's responses.

Key Strategies for Effective Intervention

  • Cues: Use various cues to assist the child, such as:

    • Pragmatic cues: Indicating when communication has broken down or is unclear.

    • Modeling cues: Show proper pronunciation or clarify misunderstood sounds.

  • Frequency and Duration of Sessions: Aim for high engagement with approximately 100 production practice trials per session.

  • Assessment of Progress: Continuously monitor effectiveness through treatment and generalization data.

Conclusion

  • Integration: Aim to integrate these therapeutic approaches with practical applications and thorough understanding to ensure effective treatment of SSDs.

  • Review and Adaptation: Regularly revisit intervention strategies to adapt based on the child's response and progress.
