I need help. I have a Mexican restaurant who wants to look into a voice receptionist, however, in building out the system in Retell, it appears to struggle significantly when listening to the user speak Spanish. When the user speaks English it works just fine. Obviously you can see that no restaurant owner is going to buy a system that struggle significantly when it can't speak to its users. So I've considered using Vapi, I've never used it before. Do you guys know if it works well with speaking and understanding Spanish fluently and with speed? Please help.
