Language detection could be used in which of the following technologies?

Language detection can be utilized within both Power Automate and Power Apps, making the choice that includes both platforms the correct one.

Power Automate, as a tool for automating workflows between applications and services, can leverage language detection to process natural language inputs. This capability can be beneficial in scenarios where automated responses or tasks depend on understanding the user's language preference, especially when integrating with AI services or APIs that offer language recognition features.

Similarly, Power Apps can incorporate language detection to enhance user experiences within applications. For example, an app can adjust its interface or provide translated content based on the detected language of the input from users. This is particularly valuable for applications designed for a diverse audience, ensuring accessibility and improved usability.

Thus, since both platforms have functionalities that support language detection, utilizing this feature in both Power Automate and Power Apps exemplifies a comprehensive approach to improving communication and user interaction across the Microsoft Power Platform.
