About

Articulation IV

Features
Read full description

Speech Therapy for school and home practice! Articulation IV has four of the most common articulation targetsβ€”R, S, L, and Th–in the Initial, Medial, Final positions and in Consonant Clusters. Buttons on the screen let you listen to the word, the sounds in the word, a short phrase containing the word, and three sentences. Sentence 1 may add another of the same target. Sentence 2 includes at least 2 of the same target sound and usually is a longer sentence. Sentence 3 likely has multiple target sounds (R, S, L, and/or Th) and will be semantically complex. A clear speech model is presented for the child to imitate and they can record and play back their own speech. The clinician can choose from three scoring methods. 1. Score each response as correct, distorted or incorrect. 2. Score responses as correct, distorted, substituted, or omitted. 3. Score productions based on whether they are spontaneously correct/incorrect or imitatively correct/incorrect. New vocabulary includes words not commonly found in yesterday’s word lists but necessary for today's classroom success such as: compost, awesome, LOL, USB port, browser, search engine, etc. Sort the words by target sound and position. You'll find curriculum-based words including: computer-related words, math, time & measurement, emotions, food, music, sports and games etc… This app uses the content from LocuTour’s Articulation IV CD. There are 475 words and photographs. There are: 85 words in /r/, 189 words in vowel controlled /r/, 212 words in /s/, /z/, 117 words in /l/, 49 words in voiced/voiceless /th/. Words may be in multiple phoneme groups.

LispApp

Start learning the /s/ sound today with LispApp’s interactive exercises! LispApp is a mobile application designed to support speech therapy and to be used for practice at home. The app has been developed together with American speech-language pathologists. Both the content and structure follow effective methods used in speech therapy for practicing the /s/ sound. LispApp is suitable for children of all ages, from 3 years old up to the teenage years. However, we recommend that an adult and child use LispApp together – this way the adult can support the child when needed, while also spending quality time learning together. The structure of LispApp: Auditory bombardments – First, we learn what the /s/ sound is like. The child listens to many model words where /s/ appears in different positions. Listening for /s/ – Next, the child practices recognizing whether /s/ appears in a word or not. This strengthens awareness of the sound. Oral motor exercises – Then we practice tongue and mouth motor skills, making it possible to produce the /s/ sound at all. These exercises strengthen tongue control and airflow. Making the /s/ sound – Fourth, we start shaping the /s/ sound through the /t/ sound (t β†’ tsss β†’ s). This helps the child find the correct tongue placement and airflow. /s/ in syllables – After that, we move to syllable practice. The child works on using /s/ in simple syllables such as sa, si, su, as, is, us. /s/ in words – The final section is placing /s/ into words in different positions, as well as practicing common consonant blends. The app includes a variety of fun activities for practicing speech. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
