If you're talking about a pre-recorded greeting provided by your carrier, you'd need to ask them.
If you're taking about a custom greeting, open the Phone app, tap "Voicemail" in the lower right corner. Tap "Greeting" in the upper left. Follow the prompts to record your own greeting in whatever language you prefer.
