### Answer
Currently, Vapi supports multilingual capabilities through its partnerships with various Speech-to-Text (STT) providers like Deepgram and Talkscriber. However, if the languages you need (Urdu and Punjabi) are not supported by the existing providers, adding new language support could involve several steps:
1. Contact Vapi Support: Reach out to Vapi's support team to discuss the potential of adding Urdu and Punjabi. They might have plans to expand language support or could guide you on integrating a custom STT provider that supports these languages.
2. Custom STT Integration: If Vapi agrees or if it's viable, you could integrate a custom STT provider that supports Urdu and Punjabi into Vapi. This would require working closely with Vapi's technical team to ensure compatibility and performance standards are met.
3. Use an External STT Service: You could use an external STT service that supports these languages and then pass the transcribed text to Vapi for processing. This would require handling the interactions between the external STT service and Vapi's APIs.
For detailed guidance and to see if there are any updates or workarounds for integrating additional languages, it's recommended to check the official documentation or directly contact Vapi's support.
