To develop an app that reads recipe instructions aloud for the visually impaired, which version of service should you utilize?

1. Text Analytics

2. Speech

3. Computer Vision

4. Optical Character Recognition

The correct answer is: Speech

Utilizing the Speech service is the most suitable choice for developing an app that reads recipe instructions aloud for visually impaired users. This service is designed to convert text into natural-sounding speech, which is essential for providing auditory instructions. By using the Speech service, your app can take the text of the recipe and synthesize it into spoken words, making it accessible to users who may have difficulty reading due to visual impairments. Integrating the Speech service allows for customization of voice options, pitch, and speed of speech, enhancing the user experience for individuals relying on auditory information. This capability is crucial for ensuring clear and understandable delivery of instructions, which is particularly important in a cooking context where precise information is necessary. Other options such as Text Analytics focus more on extracting insights and understanding from text but do not provide audio output. Computer Vision is used to interpret and understand visual content, which would not fulfill the requirement of reading text aloud. Optical Character Recognition (OCR) is specific for converting images of text into machine-encoded text, which is a useful step if you are starting from printed recipes, but again, it does not produce speech. Thus, the Speech service is the most directly aligned with the goal of providing audible recipe instructions.
