Hey everyone, I'm conceptualizing a custom voice assistant using VAPI and have some questions about the model assistant system prompt box. My use case is that I will be cloning the voice of a well known individual (with their consent, and in collaboration with them) and then setting up the voice assistant to answer questions and engage with callers exactly as said individual would. Let's take Dr. Phil as an example. If I wanted to add a very large amount of call guidelines that should answer as if it were actually Dr. Phil, like "If the caller asks about advice whilst navigating their divorce, you should answer with blah.. blah..", "If the caller asks about drug addiction, you should answer with blah.. blah..", etc... etc... My question is, is there a character limit for the model assistant prompt box? Also, any tips for prompting for setting up such a model? Any advice would be much appreciated!

Vapi’s assistant system prompt box has a 5,000-character limit, so you’ll need to structure your Dr. Phil-style guidance concisely with clear sections, topic-based responses, and fallback rules for best results..

Cool, thank you!

You're welcome

@Kings_big💫 , excuse my ignorance, is there any way to correct pronunciation? For example, if the model is saying the name "Marianne" like "Mary-Ann" but I want it to say it more like "Murry-Aan" instead? Secondly, does Vapi support Afrikaans, as in, understands when the caller speaks it and then responds, in Afrikaans, using a custom Afrikaans voice from Eleven Labs?

Yes, you can correct pronunciation using SSML like, tags, and it supports Afrikaans by allowing speech recognition in the language and replying using a custom Afrikaans 11Labs voice..

Wow, Epic! That's amazing! (I don't think Retell offers that, so well done Vapi 💪 )

Yes, vapi supports Zulu and Xhosa as long as you configure it with a transcription provider like Deepgram and a text-to-speech provider like Azure that support those languages..
