As of my knowledge cutoff in April 2023, I don't have specific information about the availability of an OpenAI Voice mode for VAPI or its support for the German language. However, VAPI is designed to be flexible and can integrate with various LLM providers, including those that offer multilingual support. If OpenAI has released a voice mode that includes German language support, it may be possible to integrate it with VAPI, depending on compatibility and API offerings.
For the most accurate and up-to-date information, please refer to the official VAPI documentation or contact VAPI support directly. They will be able to provide you with the latest updates on feature releases and language support.
