so i working on a website that user can practice pitching with ai, cuz the theme is export thing. Example, when buyer is from japan, the vapi will act as a japanese buyer

Yes, Vapi supports multiple languages including Japanese. To configure a Japanese-speaking AI buyer, you can use this configuration:

json
{
  "voice": {
    "provider": "azure",
    "voiceId": "ja-JP-NanamiNeural"
  },
  "transcriber": {
    "provider": "deepgram",
    "language": "ja"
  }
}

You can implement this using the Vapi Web SDK to integrate with your website. Sources: - [Vapi Multilingual Support documentation](https://docs.vapi.ai/customization/multilingual) - [Discord message about multilingual support](https://discord.com/channels/1211482211119796234/1344659837941977170)

what if, i'm still want the vapi talk english but the accent is japanese is that possible?

@Fabiansky Trafada Perkasa You can find an en-US voice with Asian / Jap accent. Browse ElevenLabs voice collection, they should have one. You can then use 11 labs as the voice provider and put the voice ID. It should work.

You can also do accents with cartesia voices, you can prompt LLM to act like person from some country

By configuring a webhook to return a transient assistant tailored to each buyer persona, using custom prompts, localized voices, and optional KB for realistic simulations.
