The Speech Assessment and Interactive Learning System (SAILS) is an app-based tool for presenting children with recordings of other children's speech. The recordings represent children's efforts to perceive difficult sounds, some articulated correctly, some misarticulated. The child's task is to determine if each auditory stimulus is a correctly articulated variant of the target word. Four published studies have shown that a child's rate of progress in speech therapy will be double the usual rate if the program is included as part of a typical speech therapy program. SAILS is available in North-American English (8 speech sounds can be tested and trained across 21 modules) and Australian English (5 speech sounds can be tested and trained across 10 modules). You can try SAILS with the CAT module that is free in each language. One module (GRIS) is available for free in French.

Verdict

The call

The clearest difference is rating: Proloquo at 4.0 against SAILS's 3.0. Proloquo also leads on ratings volume (148 vs 1) and update cadence (every 6 weeks vs every 5 months). SAILS's advantage is monetization model (free with in-app purchases vs subscription) and iOS requirement (11.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
