Imagine having a heart-to-heart with Shakespeare, strategizing with Sun Tzu, or bantering with Batman - all through your phone. Thanks to Character.ai's latest feature, "Character Calls," this sci-fi scenario is now a reality. As reported by tech journalist Eric Hal Schwartz and published on TechRadar, the company's new "Character Calls" feature is turning heads in the digital world.

Users can now engage in voice conversations with an array of AI-generated personalities, from historical figures to fictional characters, in seven different languages. It's like having a phone book filled with the most interesting people from across time and imagination.

But it's not just about star-struck fan interactions. Character.ai reports that over 3 million users have already made more than 20 million calls, using the feature for practical purposes like language practice, interview prep, and creative brainstorming.

With over a million voice options available, the possibilities seem endless. Want to create your own AI chatbot with a specific accent? Go for it. Fancy a chat with a Shakespearean-accented AI version of your favorite superhero? Why not?

As the virtual companion market heats up, with tech giants like Meta and Google jumping on the bandwagon, Character.ai's move to add voice interaction could be its trump card in keeping users engaged.

So, next time your phone rings, it might just be your new AI best friend calling. Welcome to the future of conversation - it's virtually limitless.
