What is the recommended treatment approach for individuals with speech delays or disorders?

Speech Therapy for Speech Delays and Disorders

The treatment approach for speech delays and disorders must be tailored to the specific type of disorder: parent training programs (11+ sessions) for expressive language delay in late talkers, phonological treatment methods for speech sound disorders, and intensive speech restructuring techniques combined with psychological interventions for stuttering, with all approaches requiring concurrent treatment of any comorbid mental health conditions. 1, 2, 3

Initial Diagnostic Differentiation

The first critical step is determining the specific type of speech disorder, as this fundamentally changes the treatment approach:

• Developmental language delay (late talkers): Children in their third year with expressive language delay who are at risk for persistent developmental language disorder 2
• Speech sound disorders (SSDs): Phonological or phonetic articulation problems requiring different intervention strategies 4, 2
• Stuttering: Must differentiate between developmental stuttering (childhood onset) versus functional stuttering (adult-onset, often with psychological triggers) 5, 6
• Functional articulation disorders: Acquired speech problems often associated with excessive musculoskeletal tension 1

A comprehensive speech evaluation should assess substitutions, distortions of specific sounds, unusual prosodic features, and exaggerated tongue, lip, or jaw movements 5

Treatment by Disorder Type

For Expressive Language Delay (Late Talkers)

Parent training is the primary intervention for children with isolated expressive language delay:

• Group parent training programs providing at least 11 sessions show significant benefit (Hedges g = 0.38 to 0.82) 2, 3
• Less intensive interventions (6 sessions) show no benefit 3
• Parent-administered interventions are as effective as clinician-administered therapy 7

Direct language therapy is indicated when:

• Receptive language delay is also present 2
• Additional DLD risk factors exist 2
• Duration should exceed 8 weeks for optimal outcomes 7

For Speech Sound Disorders

The approach depends on whether the disorder is phonological versus phonetic:

Phonological speech sound disorders (pattern-based errors):

• Use phonological or integrated phonological treatment methods (Cohen's d = 0.89 to 1.04) 2
• Consider maximal or multiple oppositions approaches that target phonological patterns 4
• Include speech perception and phonological awareness skills, not just production 4

Phonetic speech sound disorders (isolated motor errors):

• Use motor-based approaches for isolated phonetic errors 2
• Lateral lisps and residual speech sound errors require different evaluation and treatment than other speech sound errors 4
• Traditional articulation therapy is appropriate only for this subtype 4

For Stuttering

Address comorbid mental health conditions first or concurrently, as depression and anxiety significantly worsen stuttering outcomes and prevent maintenance of treatment gains 8, 6:

• Initiate SSRI antidepressants as first-line treatment for comorbid depression or anxiety 8, 6
• Consider low-dose amitriptyline as an alternative 8, 6
• Refer to psychiatry for structured psychotherapy (CBT, acceptance and commitment therapy) 1, 8

Speech restructuring and fluency shaping techniques include intensive programs (Prolonged Speech Treatment Model, Camperdown Programme, La Trobe Smooth Speech Clinic Programme) delivered individually or in groups 1:

• Slow rate of speech 1
• Easy, gentle onset with elongating vowels and producing prolonged speech 1
• Link words together with controlled phrasing 1
• Emphasize speech naturalness 1
• Determine hierarchy of speaking situations with desensitization tasks 1

Symptomatic interventions targeting physical tension:

• Reduce excessive musculoskeletal tension in head, neck, shoulders, face, and mouth 1, 8, 6
• Slow speech down or elongate sounds rather than building tension ("resetting the system") 1, 8
• Use dual tasking while speaking as distraction 1, 8
• Introduce mindfulness during speech tasks to maintain focus on easy, smooth movements 1, 8
• Use nonsense words or syllable repetitions to demonstrate potential for normal fluency 1, 8

For stuttering specifically (Lidcombe Program): Speech-language pathologist-delivered intervention featuring parent training reduces stuttering frequency by 2.3% to 3.0% of syllables stuttered at 9 months, effective both in-clinic and via telehealth 3

For Functional Articulation Disorders

Education and reassurance about the nature of symptoms and good prognosis for resolution 1:

• Explain how we actually speak versus how we think we speak (pronunciation doesn't follow spelling) 1

Symptomatic interventions:

• Reduce excessive musculoskeletal tension in speech and non-speech muscles of head, neck, shoulders, face, and mouth 1
• Collaborate with physiotherapy or occupational therapy for functional facial weakness, spasm, or trismus 1, 5, 8
• Eliminate secondary or accessory movements through distraction techniques 1
• Focus on normal movements and sounds, distracting from abnormal sounds 1
• Invite non-speech articulation such as singing 1
• Advance communication with higher cognitive linguistic content in hierarchical fashion 1

Psychological Interventions Across All Disorder Types

Communication counseling addressing predisposing, precipitating, and perpetuating issues:

• Address abnormal illness beliefs, excessive attention and vigilance toward bodily sensations, and sense of loss of control 1
• Identify and challenge maladaptive cognitions including hypervigilance to speech difficulties 1, 8
• Target features related to locus of control and executive function 1, 8
• Teach adaptive responses to moments of difficulty using less struggle and tension 1

Assess and address psychosocial stressors:

• Evaluate life stressors including relationship conflicts, workplace stress, recent accidents/illness 5, 8
• Screen for trauma history including PTSD, head injury, or other traumatic events 5, 8
• Identify avoidance patterns (situations, words, or speaking contexts avoided due to fear) 5, 8

Education about anxiety physiology:

• Teach about the anxiety arousal curve and importance of avoiding avoidance 1
• Provide CBT strategies to identify and challenge beliefs, cognitions, and self-reported sensations 1

Referral Criteria

Refer to speech-language pathologist and audiologist when speech and language delay is suspected 9

Refer to mental health professionals when:

• Significant anxiety or psychological distress is present 1, 5, 8
• Comorbid depression, anxiety disorders, or PTSD exists 8, 6
• Long-standing anxiety, comorbid depression, or ongoing medicolegal/workers' compensation issues are present 1

Multidisciplinary collaboration with physiotherapy or occupational therapy for functional facial weakness, spasm, or trismus 1, 5, 8

Critical Pitfalls to Avoid

Do not focus exclusively on speech symptoms while ignoring psychological factors, as this leads to treatment failure and relapse 5, 8, 6

Do not use traditional articulation therapy for all speech sound disorders, as many children require phonological approaches or interventions targeting speech perception and phonological awareness 4, 2

Do not provide communication aids that perpetuate avoidance patterns; encourage direct communication without technological supports that reinforce dysfluent behaviors 8, 6

Do not assume absence of a clear psychological trigger excludes a functional diagnosis; functional disorders can occur without obvious precipitants 5, 6

Do not delay mental health referral when significant anxiety or depression is present, as these conditions must be treated concurrently for successful speech therapy outcomes 8, 6

Do not use interventions shorter than 8 weeks, as longer duration therapy is associated with better clinical outcomes 7
