An idea from Nadia: Take a photo with a phone, make an app to recognize text (Chinese) in the photo and to read it out loud as a way to learn Chinese.
General outline: Pipe camera image to OCR then to a Text-to-Speech engine.
Available resources, best I found thus far:
- Google Cloud Vision (OCR) API https://cloud.google.com/vision/
- Google Cloud Text to Speech https://cloud.google.com/text-to-speech/
Though they have pricing plans, they seem to offer free plan with limitation (number of scans) that's of no serious consequences for basic usage.
