"""Use this method to send audio files.
Parameters:
chat_id (``int`` | ``str``):
Unique identifier (int) or username (str) of the target chat.
For your personal cloud (Saved Messages) you can simply use "me" or "self".
For a contact that exists in your Telegram address book you can use his phone number (str).
voice (``str``):
Audio file to send.
Pass a file_id as string to send an audio that exists on the Telegram servers,
pass an HTTP URL as a string for Telegram to get an audio from the Internet, or
pass a file path as string to upload a new audio that exists on your local machine.
caption (``str``, *optional*):
Voice message caption, 0-1024 characters.
parse_mode (``str``, *optional*):
Pass "markdown" or "html" if you want Telegram apps to show bold, italic, fixed-width text or inline
URLs in your caption. Defaults to "markdown".
duration (``int``, *optional*):
Duration of the voice message in seconds.
disable_notification (``bool``, *optional*):
Sends the message silently.
Users will receive a notification with no sound.
reply_to_message_id (``int``, *optional*):
If the message is a reply, ID of the original message
reply_markup (:obj:`InlineKeyboardMarkup` | :obj:`ReplyKeyboardMarkup` | :obj:`ReplyKeyboardRemove` | :obj:`ForceReply`, *optional*):
Additional interface options. An object for an inline keyboard, custom reply keyboard,
instructions to remove reply keyboard or to force a reply from the user.
progress (``callable``, *optional*):
Pass a callback function to view the upload progress.
The function must take *(client, current, total, \*args)* as positional arguments (look at the section
below for a detailed description).
progress_args (``tuple``, *optional*):
Extra custom arguments for the progress callback function. Useful, for example, if you want to pass
a chat_id and a message_id in order to edit a message with the updated progress.
Other Parameters:
client (:obj:`Client`):
The Client itself, useful when you want to call other API methods inside the callback function.
current (``int``):
The amount of bytes uploaded so far.
total (``int``):
The size of the file.
*args (``tuple``, *optional*):
Extra custom arguments as defined in the *progress_args* parameter.
You can either keep *\*args* or add every single extra argument in your function signature.
Returns:
:obj:`Message`: On success, the sent voice message is returned.
``None`` -- In case the upload is deliberately stopped with :meth:`stop_transmission`.
Raises:
RPCError: In case of a Telegram RPC error.
