Assistive Technology for Inclusive Communication: Nagish and Ava

Assistive technology includes tools, devices, and systems designed to support people with disabilities, enhancing their ability to perform daily tasks, and communicate. One such innovative tool is the Nagish app, which breaks communication barriers for people who are deaf, hard of hearing, or have speech disabilities. By addressing both individual needs and societal barriers, Nagish exemplifies how technology can foster inclusion and independence.

Overview of the Nagish App

Nagish is a mobile and web-based application designed to make phone conversations accessible for people with hearing or speech disabilities. It allows users to engage in phone calls through real-time conversion of speech to text and text to speech. This approach aligns with the medical model of disability, which sees technology as a way to address the functional limitations experienced by individuals.

Key Features of Nagish

  • Real-time Speech-to-Text Conversion: During phone calls, Nagish converts spoken words into text, allowing individuals who are deaf or hard of hearing to follow the conversation in real time.
  • Text-to-Speech Functionality: For people with speech disabilities, the app converts typed text into spoken words, enabling clear communication during phone calls. This feature helps bridge the gap between the individual’s physical abilities and societal expectations.
  • Privacy and Security: Nagish ensures that phone calls are encrypted, maintaining user privacy. This autonomy in communication is critical for individuals who may rely on third-party services in other settings.
  • No Need for Interpreters: By automating communication, Nagish removes the need for third-party interpreters, allowing users to communicate more privately and independently.
  • Multiple Language Support: The app supports various languages, ensuring broader accessibility for users from different linguistic backgrounds.

Benefits and Impact

Nagish allows people with hearing or speech disabilities to engage in phone calls without the need for a third party, which reflects the social model’s goal of reducing societal barriers. Furthermore, Nagish works with any phone number, enabling individuals to communicate with others who do not use the app. The real-time transcription and text-to-speech features offer a faster, more streamlined communication process than traditional methods such as relay services.

Challenges and Limitations

Despite its many advantages, the Nagish app faces some challenges. Transcription accuracy is not always perfect, with potential issues in understanding accents, background noise, or rapid speech. Additionally, Nagish requires a stable internet connection to function properly. Although Nagish works well for straightforward communication, it may not capture the emotional nuances or subtleties required in more complex conversations.

The Ava iOS App

Ava is an iOS app that provides real-time transcription of spoken conversation, making verbal communication more accessible for people who are deaf or hard of hearing. Designed to be easy to use, Ava has a simple and minimal interface that allows users to start captioning quickly. In addition, features like speaker identification and text size adjustments are customizable, which makes it adaptable to different users’ needs.

Models of Disability and Accessibility

Ava’s real-time transcription feature aligns with the social model of disability by removing a communication barrier that often isolates deaf or people with hard of hearing. By offering real-time transcriptions, Ava enables participation in conversation where sign language interpreters or other accommodations may not be available. However, from the perspective of the medical model, its reliance on AI-driven transcription may be perceived as addressing an individual deficit rather than advocating for universal captioning solutions.

Economic and Functional Limitations

The economic model of disability considers the financial burden of accessibility solutions. In Ava's multi-speaker premium feature, it requires a premium paid subscription, and this cost barrier may prevent some users from accessing its full benefits. There are also functional limitations: the identification of the speaker will not always be a 100% accurate. Moreover, for the sign language user, the text captions have limitations in capturing the grammar and structure of the sign languages, which could potentially create a gap.

Summary of Features for Nagish and Ava

Below is a comparative breakdown of the key characteristics of these two technologies:

  • Nagish Primary Focus: Mobile and web-based call captioning with real-time speech-to-text and text-to-speech.
