Clusters Complex Lite 2.0.2

This review concerns the free version of Clusters Complex Pro, which includes the /shr-/ cluster and five thematic categories for initial evaluation. However, the full version offers a more comprehensive set of features designed to enhance speech Language Pathology therapy.

The complete Clusters Complex Pro encompasses a range of practical elements:

• Coverage of complex English consonant clusters such as CC and sCC clusters (/θr-/, /fl-/, /fr-/, /sl-/, /shr-/, /str-/, /skr-/, /spr-/, /skw-/, /spl-/)
• Targeted speech elements including:
  • Words (88)
  • Phrases (440)
  • Sentences (440)
• Vivid visual aids, including photographs and videos, to support engagement
• A selection of over 30 thematic categories, featuring sports, animals, and various activities; each comes with dedicated buttons, backgrounds, and reward videos to motivate learners
• Randomization feature to present stimuli in varied sequences for better generalization
• Self-monitoring capabilities, encouraging active learner participation
• Progress tracking tools for ongoing assessment and documentation
• Customizable motivational messages tailored to individual learners
• Robust data collection functionality, including audio recordings that can be emailed, backed up to computers, or stored on Apple devices

The application is designed to provide targeted intervention focused on the ten most complex consonant clusters, including three-element and intricate two-element formations. It features a database of 968 photographs representing 88 words, 440 phrases, and 440 sentences. Learners can select themes that align with their interests, such as specific animals or activities. The randomization feature offers varied presentation orders to promote robust learning. Additionally, children can participate in self-monitoring and receive short reward videos contingent upon achieving high accuracy levels.

Speech-Language Pathologists benefit from monitoring capabilities through audio recordings and data collection tools that facilitate progress tracking over time. All collected data can be backed up or shared via email for comprehensive documentation.

Word selection within the app emphasizes complex consonant clusters with consideration of phonetic development. For example, words containing /skw-/ such as “squad,” “squeaky,” and “squeeze” were selected, intentionally excluding words like “square” or “squabble,” where final sounds may detract from focusing on initial cluster articulation. Similarly, phrases and sentences are crafted to incorporate early-developing sounds surrounding the target clusters—examples include “white floppy hat,” which emphasizes the /fl-/ cluster amidst surrounding sounds like /w t p h/, and “We took a flight to Maine,” providing contextual facilitation.
