Its a combination of many things, intonation and delivery, politeness (formality, honorifics etc.) level, word choice, particle choice.
Its known as onnarashii (女らしい) speech.
Its a historical thing which is gradually falling out of use. These days you tend to only mostly find it in situations where the politeness levels are needed/expected (e.g. hospitality industry).
Imagine a male, non-native English speaker learning from a group of stay-at-home moms. Deep South, Midwest, take your pick. He's gonna pick up some stuff. Men in the US aren't expected to say "Aw honey," or "Bless yer heart!"
the same goes for many langauges, but you need to learn the same japanese but different form and way its spoken. I had this issue too, luckily a few japanese women helped me OL/dates so I could steer but this is a big issue
and I put a video in to try and apparently there's a 26 minute wait
Like it has a sentence he said in Japanese, in English, and you have to translate it back to Japanese? But the sentence isn't a really a response to anything, it's just something the guy said
I don't get it
Does this not exist yet?
My stack, running locally on a Windows 10 machine: - Vosk STT augmented with vosk-model-ja-0.22 for Japanese - Gemma4 LLM running in Ollama and with customized model card to act as a Japanese tutor - Kokoro TTS using Japanese voice jf_alpha.pt and augmented with the unidic Japanese dictionary
Not that I would trust an AI chatbot with Japanese. Most online text translators can barely cope with Japanese, DeepL is the only one that provides passable results. Its a tricky language.
