I want to know what`s the TTS , STT inside Vapi setup to build an outbound cold outreach to Serbian speaking customers ?

To set up a Serbian outbound voice assistant in Vapi, configure your assistant with a multilingual TTS/STT provider (e.g., Azure for TTS, Google STT for transcription). Here’s a sample configuration:

json
{
  "voice": { "provider": "azure", "voiceId": "sr-RS-NevenaNeural" },
  "transcriber": { "provider": "google", "language": "sr" }
}

Replace

voiceId

and

language

with the exact Serbian options supported by your chosen provider. Test your setup to ensure Serbian is recognized and spoken correctly.
