Do you already talk to your chatbot out loud? And in which area is it helping you the most?
Voice assistants in chatbots are no longer just sci-fi. Thanks to artificial intelligence, they have become partners that can lead meaningful and personalised conversations. From customer service to education, their use is incredibly wide.

Summary and recommendations
Voice assistants today differ more than it might seem at first glance. In some tools you get a smooth conversation in Czech, in others advanced work with your own data or multimodal input, but at the cost of certain limitations or weaker localisation. If you know what you want to use the assistant for and in which language you will communicate, choosing the right tool quickly starts to make sense.
