At around 30 seconds in[2], an AI agent types and says, "Hi! Welcome to our design studio." to which a customer responds「すみません、日本語で話してもいいですか?」(Sorry, may I speak Japanese?).
The AI agent then says 「もちろんです。日本語に切り替えましょう。」(Of course. Let's switch to Japanese.) but types「ご心配なく。数量は柔軟に対応できます。」which means "No worries. We can be flexible with the quantity."
Their TTS is good but unfortunately the exemplar widget is not nearly up to the same quality.
You should have learned something from the Sesame AI demo and the hype it generated for them.
It'd be incredible to get to a point where we can have natural conversations and the AI is running tools in the background and keeping tabs on things.
