***Now with ability to upgrade at a discount*** Whether you’re a speech and language pathologist (SLP), an SLP college student, a parent of children with speech delays, or someone trying to improve their American English accent, you’re going to find this an invaluable application. A first of its kind in the field, Speech Tutor brings the latest in technology and animation to the world of speech. The animations inside Speech Tutor take the areas of the face that impede the view of tongue placement and positioning and make them transparent. Now one can literally see inside the mouth as the sounds are being made! Speech Tutor offers a “Side View” and a “Front View” of each sound production, both of which can be viewed at 3 different speeds (slow, medium, fast). The movies can also be paused any given point. With 132 animations in all, Speech Tutor is sure to offer a helpful view and speed for anyone in need. Speech Tutor does not stop there though. Non SLPs can begin the application by reading an easy to understand “Basics” tutorial which provides the reader with a solid foundation of the basic knowledge needed to know before attempting to improve any/all English consonants. Also provided is detailed text specific to each sound that further describes how each sound is technically made, tips provided by licensed speech and language pathologists, and milestones for when each sound should be acquired and mastered. Along with viewing the animations, one can also view a “Palate” diagram to further demonstrate where on the palate the tongue should be placed. Last but not least, users of the application can choose to record themselves as they practice their target sounds and then choose to play it before and after a correctly modeled production. Animations for the following sounds are provided: P, B, T, D, K, G, N, M, ING, F, V, S, Z, SH, CH, J, L, R (retroflex and bunched), TH (voiced and voiceless) and 4 new vowel animations - /i/, /u/, /a/ and /æ/

Wonster Words combines interactive phonics puzzles with engaging animations to make reading feel like play. Kids explore words by dragging letters into place, hearing their letter names and sounds, and watching hilarious animated shorts that bring vocabulary to life. • "As a 1st grade teacher with a kindergartener [son] I know how important it is to keep learning interesting. This is my son's favorite app and mine too." • "I downloaded this game for my 2 yr old daughter and she is always running off with my phone to learn some new words." _______________________ BASED ON THE SCIENCE OF READING Wonster Words is built around phonics-based learning, research-backed principles that support early reading success. Kids go beyond basic ABCs and phonics—they learn how letters form blends, digraphs, word families, diphthongs, and CVC words, all key building blocks for fluency. • "This app really helps reinforce the phonics principles and sight words we go over daily. I love that my children are eager to learn and have fun doing it." • "[My 5 year old] has been using Wonster Words each night and has started to spell on his own. We are sounding out words together.

With our Custom Word List feature, parents and teachers can enter their own words, and Wonster Words will automatically generate phonics-based spelling lessons tailored to those words. • "I love this for my child’s spelling words.

It’s an excellent supplement for speech therapy and a motivator for kids working on communication skills. • "My three year old was slow to articulate many words.

He's four now and still loves this app. Non-stop chatterbox with a huge vocabulary." • "I am a retired Speech-language Pathologist and I provide training for preschools. I love this app for vocabulary building, early reading and spelling." _______________________ FITS YOUR NEEDS Wonster Words supports offline play when traveling. It is safe for kids and ad-free.
