Hamaguchi Apps for Speech, Language & Auditory Development's groundbreaking iPad app is designed for older elementary through high school students, who would benefit from practice interpreting vocal intonation, facial expressions, perspective-taking, body language, and idiomatic or slang expressions. Using real photographs, voices and short mini-video clips of a variety of social situations and expressions, this app provides a dynamic way to help learn and practice interpreting messages that are “between the lines” and simply can’t be replicated with worksheets and static flashcards. Check out our demo of this app on Youtube: https://www.youtube.com/watch?v=rRy4QF1E1Y8 This Lite app provides 12 samples of each of the three activities for a total of 36 tasks and is for a single user only. (The full version provides a total of 199 tasks) This app uses American expressions and body language. There are three activities in this app: 1. Listening: The user hears a voice speak a sentence, e.g., “What did he say?! Are you serious?!” (Often the same phrase is heard spoken in several different ways throughout the activity, but with different emotion and inflection) A question is then asked, “Who said it?” The user is shown a series of photographs. The user touches the correct facial expression that matches the voice. 2. Body Language: A very short video-clip is shown that depicts an interaction or situation. For example, in a scene at a park, there are two girls whispering to each other and clearly having “girl talk”, and giggling. Another girl walks up and attempts to join the conversation, but is ignored. The camera closes in on this actor and the narrator says, “What is she thinking?” The user’s task is to look at the choices of responses and select the one that matches the facial expression/body language. 3. Expressions: A very short video-clip is shown that depicts an actor speaking a sentence that contains an idiomatic or slang expression, e.g., “They caught the burglar red-handed.’” The user is then asked, “What does that mean?” Choices are provided. The lite version is for a single user only. The percentage correct is reported for each user’s performance on each of the three activities. The user can select his/her own individual settings. Settings include: Selection of the activities, order of the activities (or random), praise phrases and correct sound effect bell on/off; answer choices (group of 2, 3 or 4), how to display choices (automatically or manually) and whether to move forward automatically or by touching an arrow. Progress can be tracked, and displayed or not displayed. One reward animation is included (Dunk Tank). This is not a game of skill but a fun diversion, which can be turned off or set to intervals. *Please contact our tech support if you are experiencing any technical issues with our apps.
