According to the official Genesys Cloud CX documentation for bulk prompt imports, the audio files must adhere to a specific naming convention to be processed correctly. The required format is prompttypeprompt-namelanguage-code.wav. For a user prompt named “Welcome” intended for the English (United States) language (en-us), the correct filename structure is promptuserWelcomeen-us. This format uses underscores to separate the three required components: the prompt type (user), the prompt name (Welcome), and the language code (en-us).

A. prompt user Welcome/en-us: This option is incorrect because it uses spaces and a forward slash as separators, which violates the required underscore-separated format.

B. promptuserWelcome/en-us: This option is incorrect because it uses a forward slash to separate the prompt name from the language code, not an underscore.

C. prompt user Welcomeen-us: This option is incorrect because it uses a space between "prompt" and "user" instead of the required underscore separator.
