ProSlate™ Series and AAC Apps: Highlighting Proloquo2Go

Updated: Jun 6, 2023

The ProSlate™ Series from Forbes AAC are iOS-based speech generating devices that can run almost any AAC app on the market using iOS-based software. This week’s blog post aims to highlight the many different features and strengths of the AAC app Proloquo2Go!

Proloquo2Go has a wide range of vocabulary levels and grid sizes which allows this system to meet the needs of AAC users from beginning communicators to advanced communicators.

Proloquo2Go offers two different vocabularies - Crescendo and Gateway

  • Crescendo™ Vocabulary: This AAC vocabulary was designed to address consistent core word placement while also providing fringe vocabulary opportunities to personalize and motivate users. Crescendo provides three vocabulary levels in 23 different grid sizes.

  • Gateway to Language & Learning©: Developed in 1997 by Joan Bruno, Ph.D., CCC-SLP, is a research-based core word vocabulary that has five vocabulary levels. Each vocabulary level addresses different communicative functions and is appropriate for user's of varying abilities.

Features of Crescendo

  • Available in multiple languages including English for the US, UK, and Australia, Spanish, Dutch, and French.

  • The VocaPriority™ system offered through Crescendo allows clinicians and family members to organize an AAC user's pages based on their priority - vocabulary utilized more frequently can be prioritized in the primary level!

  • Core words maintain the same location throughout Crescendo allowing user's to formulate many different phrases and sentences while also having quick access to relevant fringe vocabulary.

Features of Gateway

  • Gateway series has five symbol- and text-based vocabularies (Child Functional, Teen/Adult Functional, Developing Language, Advanced Communicator, Text) in various grid sizes to meet a user's unique needs.

  • Promotes efficient communication as a user can access vocabulary in an average of <1.5 key selections per word.

  • Gateway has other features (Sentence Development Links, Semantic Power Strips and Dynamic Morphology) that were developed to maximize language development and strengthen an AAC user's communicative efficiency.

Crescendo supports bilingual communication!

  • You can add any language to the same user as a second language - this allows the AAC user to easily switch between languages through the Tools popup (located in the bottom left corner).


  • This app has over 20,000 SymbolStix symbols and you can also add your own photos

  • Modify buttons (color, font, border) as needed

  • Expand the grid size as a user's language grows with confidence that the customizations you have done will be retained

  • You can also backup a user's profile - this can be done through iCloud, Dropbox, or Google Drive.

Word Search

  • It's easy to do a word search in Proloquo2Go! Just open the tools popup, tap search, and then the system keyboard will generate. Then just type a word you want to find!

  • This is a great tool for clinicians or caregivers new to the system who want to model a specific word. You can use this word search feature to find the target word, then model how to navigate to the word!

Access Methods

  • Within the app, you can modify the direct touch settings (e.g., hold duration, select on release) to maximize the system efficiency for the user

  • You can also program Proloquo2Go for switch access through the app's built-in scanning options that work with most switch interfaces
