What it Does!
Speech Trainer 3D provides an animated 3D video and audio model for 24 consonants and 7 vowel sounds. Designed by a certified speech-language pathologist, Speech Trainer 3D is perfect for those individuals struggling with sound production including children with speech delays, adults following a stroke, or individuals looking for accent reduction.
Speech Trainer 3D is perfect for SLPs, special educators, and parents.
Speech Trainer incorporates both an animated video of the speech sound as well as a systematic breakdown for describing the movements necessary for each sound. Both video modeling and video prompting are useful for many individuals when learning new skills (Evidence-Based Practice, 2010).

In addition to the animated video model, Speech Trainer 3D uses the camera function built into the iPad 2 and higher to allow the learner to see a side-by-side picture of the model and his or her own face making the sound.
Incorporating the built-in camera allows the professional to utilize both a visual and a tactile prompt for the client, which may in turn, encourage longer productions and improve the muscle coordination needed for speech (ASHA, ND).

How to Use
Speech Trainer 3D is designed to be used individually or in group practice.
Once the app is loaded, the user can choose whether to work on consonants or vowels. Simply tap ENTER from the bottom right corner, and then select vowels or consonants from the pop-up window.
Don’t worry, you can always go back and change it if you want to work on both!
When a phoneme type has been selected, the app will open with a phoneme bar along the top of the page and the side-view of a model of the speech mechanism. For consonants, the user can simply slide the selection bar sideways to access all of the consonant sounds.


When the phoneme is selected, simply tap the “play” arrow and the video model will move while the sound is produced. To hear the systematic breakdown of movements, a double “fast-forward” arrow is pushed. A square will surround the area being discussed. Subsequent taps on the double arrow will move to the next prompt.


The app opens in a default side-view; however, a frontal view is available. In this view, the speech-mechanism model is replaced with a person modeling the sounds.

The iPad camera is activated when the iPad is rotated to the landscape position. At that time, the user will see their image in the camera beside the avatar. The user will then be able to use the video modeling to make encourage accurate production of sounds.

To hear an example of words with that phoneme, simply tap the “example” button in the middle of the control screen.
Speech Trainer 3D allows the user to specify which sound in the English language to target. Transitioning between multiple sounds is easily accomplished by simply tapping on the correct phoneme on the top of the scene.


Changing from the side medical model of the speech mechanism to the mirror like human model is done with a quick tap to the controls at the bottom of each screen.
Finally, adding a self-monitoring component is encouraged by simply rotating the iPad and engaging the iPad’s built-in camera.
Speech Trainer 3D and RTI
Speech Trainer 3D is a great accompaniment for Response to Intervention (RTI). Although consult with a trained professional is always recommended, Speech Trainer 3D’s video modeling and placement tips can be used by non-professionals as an initial intervention for sound production errors.
