"Top Pick App" - Smart Apps For Kids "Erik has created a great app that students will have fun with. They might not even notice they're working!" - Home Sweet Speech Room "It's perfect for carry-over of those later developing sounds!" - Busy Bee Speech Introduction: Created by Erik X. Raj, M.S., CCC-SLP, Open-Ended Articulation is an interactive app for your iPad, iPad mini, iPhone, and iPod touch that features a collection of over 500 open-ended questions designed for speech-language pathologists to use with individuals who exhibit difficulty producing the following speech sounds: S, Z, R, L, S/R/L Blends, SH, CH, and TH. Features: -Tons of content: with just a tap of a finger, children and clinicians can discover over 500 sound specific open-ended questions that are perfect for the speech therapy setting. -Hear the question: each open-ended question has an exciting narrative audio component to it. -Hear an answer: each open-ended question has an example audio response that children get a kick out of. -Child-friendly interface: simple, intuitive, and NO in-app purchases or external links. Information: With over 2 hours worth of fun and exciting audio questions and answers, Open-Ended Articulation will trigger a tremendous amount of fantastic conversation in your speech therapy room. It is intended to aid in the remediation of articulation impairments, as well as auditory and language difficulties because clients often need practice in more than one area of communication. All of the open-ended questions require the student to use creative thinking. The client should come up with as many different ways to complete the sentence as he/she can. This is the time to encourage your student to think outside the box. Do not stop to evaluate or criticize a response. The purpose of these open-ended questions is to generate a free flowing exchange of suggestions and sentence completions with proper target sound productions. Together, you and your students will have a blast getting those creative thinking juices flowing! The open-ended question format is a departure from traditional articulation drill work and is effective for students ages 6 and up. Because of this unique format, clients enjoy asking the open-ended choice questions to their friends and classmates outside of the speech therapy room, further practicing their communication skills and thereby facilitating the sometimes difficult stage of carrying over newly-acquired skills. By reviewing the questions with the client, paraprofessionals in the classroom and/or parents at home can reinforce the client’s skills while sharing a fun activity. Practicing communication skills in environments outside the speech therapy setting increases opportunities for generalization of communication skills. Use these questions to spice up your speech therapy sessions. The questions are intended to initiate exciting and lively conversations. Every inquiry has the potential to lead almost anywhere. Even a question that appears simple can trigger a unique thought process and complex response. Regardless of when, where or how these questions are used within the speech therapy session, one thing is certain, children (as well as clinicians) will have a blast finishing these open-ended questions . . . and in the process they will continue to practice the correct pronunciation of their sounds at the spontaneous conversation level. Let your imagination run wild and have fun with this therapy material!

Many children, adolescents, and adults struggle to eliminate speech errors affecting the American English 'r' sound. Research suggests that these errors can in some cases be eliminated through biofeedback, where learners view a dynamic visual image of their speech and attempt to match a target representing correct production. staRt ("Speech Therapist's App for /r/ Treatment") aims to make biofeedback treatment for /r/ widely accessible to practicing speech-language pathologists. Features: - Tutorial explaining how to interpret and use the biofeedback display - "Free play" mode where users match their real-time visual-acoustic display to a target representing correct production of ‘r’ - "Quest" mode presenting syllables/words for 'r' practice; complexity increases or decreases in an adaptive fashion based on recent performance - "Quiz" mode for use in measuring baseline performance and tracking progress - Visual rewards reinforcing improvements in performance - Clinician dashboard tracking progress over the course of treatment
