FreeSpeech helps anyone with a language impairment practice and develop grammar skills! Drag and rearrange picture tiles, and FreeSpeech will convert them into a perfectly grammatical English sentence. Explore how tenses, sentence forms, parts of speech, and other grammatical properties change the structure of English -- and it's all visual! FreeSpeech is the perfect app for anyone who is learning the English language - whether you are - A person with special needs, such as autism, dyslexia and hearing impairments - An ELL student, trying to make sense of English grammar - Someone who loves languages and likes to explore them! Developed by an interdisciplinary team including SLPs, educators, and researchers with over 100 years of collective experience, FreeSpeech is the most advanced language learning technology currently on the App Store. The technology behind FreeSpeech was the subject of a TED talk by its creator Ajit Narayanan which has been viewed more than one million times. The development of FreeSpeech, combining engineering with generative linguistics, earned the team recognition as one of the world's Top 35 Innovators from MIT Technology Review. AS SEEN ON TED BY 1M+ VIEWERS: http://go.ted.com/CW6u "A powerful new app designed to help children of all learning levels and language abilities develop grammatically correct sentences... A welcome addition for anyone with young writers that struggle with arranging sentences or who have a language impairment that makes it frustrating to communicate." - SmartAppsForKids FreeSpeech is unique because it's the only app in the world that predicts grammar. You can throw a bunch of picture tiles at it, and the app will automatically figure out a grammatically correct sentence from them. - It's possible to manipulate words, tenses and structure as if you were manipulating building blocks. - The app lets teachers and learners model/recast/contrast various grammar rules pictorially, all the while speaking out correct English. - A teacher or therapist can configure how much prediction FreeSpeech does, and fade away its capabilities as a student develops confidence. FreeSpeech is based on solid research, and builds language by: - EXPANDING: Prompting users with questions to expand their sentences; - SCAFFOLDING: Intelligently predicting words that they are likely to use; - CONTRASTING: Visually modeling tense and sentence modifiers; - RECASTING: Automatically inserting prepositions and articles as needed; and - ERRORLESS MODELING: Automatically predicting grammar, to assemble a map of pictures into a grammatically correct English sentence. Scientific trials validating the efficacy of FreeSpeech have been presented at leading conferences in linguistics and special education. FreeSpeech features more than 2,000 symbols from Symbolstix, and is ideally suited to use alongside other AAC, articulation and education apps that use these lovely symbols. Additionally, you can customize the vocabulary with 20,000+ Symbolstix symbols. Download FreeSpeech & learn English language skills today!

Linggo makes communication accessible for people who have difficulty speaking. Linggo is an Augmentative and Alternative Communication (AAC) platform that comprises 2 applications, Linggo Learner and Linggo Coach. Designed with a behaviour analytic perspective and created in collaboration with Speech-Language Pathologists, Board Certified Behavior Analysts, Linggo incorporates evidence-based strategies to support the development of language, functional communication, speech and literacy skills (sight reading), while monitoring progress using data driven technology. The Linggo Learner app is intended for individuals who have difficulty or are unable to speak. The Linggo Coach app is intended for clinicians, care partners and parents who wish to monitor progress. Intuitive Interface Word finding is made easier when words appear based on personal context, relevance and grammatical order. Linggo Library With a robust library of over 4000 words with grammatical markers, users can create and add meaningful vocabulary to help the individual build their language skills. All images are licensed from TobiiDynavox. Language Trees (Communicator) Teach sentence structures through Language Trees. Whether you're just beginning with nouns or teaching subject-verb-object combinations, Linggo can be customized to grow with the Learner's language profile. Free Form Generative novel phrases and sentences in the moment and as needed. Use Linggo’s library or photos/images from your own device to spontaneously generate novel words, phrases and sentences. Quick Chat Functional communication is made easier with Quickchat. Phrases such as “I need the washroom.” “My way, please” and “Help me” can be expressed easily through a single tap. Transition to Text Linggo offers the Transition To Text feature which encourages the Learner to learn sight words rather than relying solely on pictures and symbols to communicate. When Transition To Text is enabled, the picture associated with the text fades or reduces in size over time, eventually disappearing to display the text (sight word) only. Transition to Speak Linggo offers the Transition to Speak feature which uses a time delay (1 to 10 seconds) to encourage the Learner to use their voice. When this feature is enabled, the word remains silent when selected - giving the Learner the opportunity to practice their speech. Coaches and Progress Reports The support and feedback of Coaches are critical and mandatory components for the success of AAC intervention - which is why we included Coaches as active users too. Coaches collect data on Learner’s communication, which is then graphed across progress reports to help make evidence informed decisions. As an authorized BACB ACE provider, Linggo offers training/education to clinicians, parents and anyone interested in learning more. ** Learner accounts can be accessed through iPads/iPhones that allow for the latest iOS updates. Linggo Coach accounts can be accessed on any iOS mobile device.
