Shameless plug: One of our engineer developed a Vision Impaired OCR app that scan and read text aloud in the user favorite language and accent with built-in TTS and translation service. Basically, the app is voice driven and require minimal interaction. All the user has to do is take a picture and the scan process starts immediately and TTS takes place after scan.
