Open a live voice conversation with one bitHuman house character in the chat. The character listens through the microphone and answers out loud for up to a minute. Use a character id from list_characters.
after · 32% of words in common
Open a live voice conversation with one bitHuman house character in a player in the chat. The user presses Start and speaks through the microphone; the character answers out loud. A conversation lasts up to 60 seconds (max_seconds), then ends by itself; call again for another. Returns session_url: when the host shows no player, give the user that link. Example: {"character": "wise-pup"}. Needs a microphone in the user's browser. Errors come back as isError: an unknown character (call list_characters and use an id whose `talk` is true), resting (live conversations are off right now; make_character_video still works).

before
Make a short video of one bitHuman house character saying the given words, in its own voice. Use a character id from list_characters. The text is said word for word: 3 to 200 characters, about 15 seconds of speech. Returns a video URL that plays inline, labelled AI character.
after · 28% of words in common
Make a short video of one bitHuman house character saying `text` word for word, in its own voice. Returns video_url (an MP4 that plays inline and expires after 7 days), duration_seconds and share_url, labelled AI character. Example: {"character": "wise-pup", "text": "Welcome back! Ready for today's lesson?"}. Limits: `text` is 3 to 200 characters and at most 19 seconds when spoken (about 15 s is typical); one video at a time per user; 10 videos per user per UTC day; the same character and text again replays the earlier clip at once. Errors come back as isError with one sentence saying what to do: an unknown character (call list_characters), text too short or too long (rewrite it), personal information such as a phone number, email or street address (remove it), busy (retry in a minute), the daily limit (try again after 00:00 UTC), resting (try later). To hold a conversation in character, write each reply yourself and call this tool once per reply.

before
List the bitHuman house characters that can speak in a video: id, name, a short description and a picture.
after · 30% of words in common
List the bitHuman house characters that can speak. Each has an id (pass it as `character` to make_character_video or talk_to_character), a name, a short description, a picture URL and `talk` (true when talk_to_character is open for it). No arguments, free and read-only; one call per conversation is enough. Only these characters can speak: real people, photos and custom voices are not supported.
