Most articulation apps are designed to appeal to children, so it can be difficult to find one with appropriate content and design to use with adults with dysarthria or apraxia. For some time now, my go-to app for working on speech sound impairments has been Pocket Artic.
Pocket SLP's Pocket Artic ($9.99 universal iOS app, see note on Android at the bottom) features real photos, recorded voice, and thousands of stimuli for a variety of sounds. Each user profile is set up to store target sounds, preferred level (word/phrase/sentence), and data. If there is no time or desire to save a profile for a user, the QuickQuiz mode allows quick access to the materials. The app features 19 consonant phonemes, s/l/r blends, and six r-controlled vowels. Onscreen toggles between initial, medial, and final positions, as well as word, phrase, and sentence levels, make for easy adjustments during therapy. Score each production using the correct/approximate/incorrect buttons on screen, and take advantage of the built-in recording feature. If the client needs more information about the sound, press the "i" button to access a diagram of the tongue and palate similar to the Speech Tutor app.
There are a few issues with this app that detract from usability. Not all audio files match the printed text exactly, tripping up clients as they practice. It can also be difficult to remember to swipe right-to-left to change stimuli because the flipping animation makes it appear that an upward swipe would change the page. Getting started with the app is something that must be learned, as the home screen doesn't offer a clear direction. Perhaps the biggest problem with Pocket Artic is that it is missing the phonemes /w, zh, y, h/; these sounds have the common element that they don't appear in all positions of English words, but they are common speech targets. While many reviewers have experienced some crashes with various versions of this app, the developers have responded with 15 updates in 3 years.
For Android users, there is an older version of this app available on the Google Play store. It costs a bit more, comes in separate phone and tablet versions, and is called Pocket SLP. It does not have all the same features and bug fixes as the latest iOS version.
