Making a wearable live caption display using Azure Cognitive Services and Ably

The text explores the development of a wearable live captioning device using Azure Cognitive Services and Ably Realtime to help individuals with hearing impairments, like the author's mother, communicate more effectively when masks obscure lip reading and pronunciation cues. The project involves creating a web app that captures audio input from a microphone, transcribes it into text using Azure's speech recognition services, and then relays the text to a flexible LED display embedded in a wearable mask. The display uses neopixels connected to an Adafruit Feather Huzzah microcontroller, with messages communicated via the MQTT protocol facilitated by the Ably Javascript SDK. The app's design includes a pixel font to render text on the display, with considerations for hardware differences in LED matrix configurations, ensuring compatibility with various display setups. Additionally, a virtual simulator was developed to test the software before deployment on hardware, and the project is open-source, encouraging further development and innovation. The potential for language translation using Azure is also noted, and the author highlights the personal impact this technology had on his mother, emphasizing the broader benefits it could offer to others facing similar communication challenges.
