The support and feedback of Coaches or communication partners are critical and mandatory components for the success of AAC intervention - which is why we included Coaches as active users too. Coaches can monitor daily progress, share experiences, and collaborate more effectively together with easy data tracking. Linggo Coach also acts as a notification system. When a Learner communicates in an active session, the Coach is notified with the Learner’s message. Coaches collect data on Learner’s communication, which is then graphed across progress reports. You can also export raw data and communication history for your own records. View progress reports on: • Total vocabulary • Word history and context of use across language and communication • Sentence history • Independence over time • Frequency of prompted and independent communication • Sentences created through aided language stimulation • Cumulative record of sight words acquired • Frequency of speech over time ** Linggo Coach accounts can be accessed on any iOS mobile device. As an authorized BACB ACE provider, Linggo offers training and education to expand communication training with evidence-based AAC strategies, insights and how-to’s as well as training sessions to receive personal support and consultation from our team of clinical experts.
