Which action must an administrator take in a Webex Contact Center voice flow to ensure...

Language and voice are separate configuration values in a Webex Contact Center voice flow using AI Agent responses. The Global_Language variable controls the response language, while Global_VoiceName selects the voice used by text-to-speech or AI-agent speech output. Setting only Global_Language to es-ES would change the language but would not guarantee the company-approved Spanish voice. Setting only a friendly voice name without the language would not guarantee Spanish recognition and generation behavior. The string en-ES is invalid for Spanish in this context because en identifies English, while es-ES identifies Spanish for Spain. The requirement asks for consistent professional executive-sounding Spanish regardless of caller location or dialect, so both values must be explicitly set after the menu selection: Global_Language to es-ES and Global_VoiceName to the approved Spanish voice system name. This gives the flow deterministic language and voice behavior. Reference: Cisco Help, Webex AI Agent Studio Administration guide; Use AI agents for customer interactions.
