App Summary

RescueVoice is a speech-generating application designed for first responders and medical personnel to facilitate communication with individuals who are unable to speak due to a medical event or neurodevelopmental condition. The associated research highlights that interactions between officials and individuals with communication difficulties, such as those with autism or intellectual disabilities, can become unsafe when behaviors are misinterpreted. By providing pre-stored, relevant vocabulary for high-stakes events, the app aims to bridge this communication gap and support a safer, more effective emergency response.

Detailed Description

Functionality & Mechanism Developed at The University of Iowa, RescueVoice is an augmentative and alternative communication (AAC) system engineered for emergency medical settings. It facilitates communication between first responders and individuals with limited or absent speech. The interface leverages a combination of tap-to-talk icons with pre-stored, context-specific vocabulary and a text-to-speech module for custom messages. Core content domains cover symptoms, pain, allergies, and medications. The system operates in both English and Spanish to support diverse populations.

Evidence & Research Context

  • The app's pre-stored vocabulary was developed based on direct input from first responders and experienced users of AAC systems.
  • Associated research highlights the critical communication challenges that can arise between law enforcement or first responders and individuals with neurodevelopmental disorders.
  • Academic literature indicates that behaviors associated with conditions like autism spectrum disorder (ASD) or intellectual disability (ID) can be misinterpreted during high-stress encounters.
  • This research underscores the need for specialized tools and training to improve interaction safety and efficacy for vulnerable populations during emergency events.

Intended Use & Scope This application is intended for use by first responders, emergency medical personnel, and clinicians to establish initial communication in acute care settings. It functions as a point-of-care communication aid, not a comprehensive, long-term AAC solution. The system is not designed to integrate with custom third-party AAC voices and requires further clinical assessment for complex cases.

Advancing inclusivity: The case for change in law enforcement training regarding individuals with intellectual disabilities and autism

Stendel et al. (2025)

Referenced in academic literature; no direct evaluation of the app
Autism spectrum disorder (ASD) and intellectual disability (ID) are two neurodevelopmental disorders that, while different, can overlap for some individuals. ASD can present itself in difficulties in areas such as communication, processing of senses, and restricted and/or repetitive behavior. ID can present itself in ways such as difficulties with social skills, reasoning, problem-solving, and processing information. This honors thesis began from the thought that both ASD and ID may make any encounter with law enforcement officers more challenging as compared to law enforcement interactions with neurotypical individuals. In fact, research referenced in this thesis project shows that police officers frequently misinterpret the behaviors that members of this community may exhibit. Such misinterpretations can lead to unsafe interactions and, in the most severe of cases, even fatalities. The purpose of this thesis is to demonstrate that officials in the current criminal justice system should examine and evaluate policies and practices concerning interactions with those in the ASD and ID community. Extant literature suggests that current police practices in some jurisdictions are not adequately preparing law enforcement officers to recognize and respond to individuals with ASD and ID appropriately, potentially placing this community in harm's way. Through an examination of various case, academic literature, and interviews with experts in the discipline, this honors thesis paper demonstrates the need for widespread, mandated police training that is ASD and ID-specific. To protect and to serve members of society, this paper asserts that law enforcement must seek to advance inclusivity within their practices and training.

UI Research Working on App to Help First Responders with Communication

University of Iowa professor Krista Davidson developed RescueVoice to help first responders communicate with patients who can't speak during emergencies, using feedback she received from emergency personnel. Davidson says the app "has the potential to be life-changing" and costs $9.99 in app stores after being funded through grants and local non-profits like the Solon Lions Club. An Ohio children's hospital is among the first users of the tablet-based app, which Davidson plans to expand to smartphones and additional languages.

Iowa educator builds app to give a voice to nonverbal patients

University of Iowa professor Krista Davidson developed RescueVoice to help first responders communicate with nonverbal patients during emergencies, using speech-generating technology with tap-to-talk icons and text-to-speech capabilities. Davidson says the app includes "vocabulary related to symptoms, pain, body parts and we also have a Spanish option now where the text is in Spanish but it will speak English to the first responder." The app costs $9.99 and was funded through grants, local nonprofits, and a $10,000 prize Davidson won from UI's entrepreneur center pitch contest.

First responders receive new resource to bridge communication barriers

University of Iowa Clinical Professor Krista Davidson developed RescueVoice to bridge communication barriers between first responders and individuals with limited speech abilities, using speech-generating technology specifically engineered for emergency situations. "RescueVoice came from first responders," Davidson said, explaining they asked for an app-based solution after being given low-tech communication methods like paper boards. The app was released in 2024 and features symbols for pain indication, medical vocabulary, and pages for allergies and preexisting conditions.

CLAS faculty member develops app to bridge gap between first responders and people with limited speech during an emergency

University of Iowa clinical professor Krista Davidson developed RescueVoice to bridge challenging communication gaps between first responders and individuals with limited speech during emergencies, using digital communication tools. Davidson created the app after years of training first responders with paper-based communication boards, noting that "each group we presented to asked, 'Is there an app for that?'" RescueVoice is now available for download in the Apple Store and Google Play.
