"""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.

file_ref (``str``, *optional*):

A valid file reference obtained by a recently fetched media message.

To be used in combination with a file id in case a file reference is needed.

caption (``str``, *optional*):

Voice message caption, 0-1024 characters.

parse_mode (``str``, *optional*):

By default, texts are parsed using both Markdown and HTML styles.

You can combine both syntaxes together.

Pass "markdown" or "md" to enable Markdown-style parsing only.

Pass "html" to enable HTML-style parsing only.

Pass None to completely disable style parsing.

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

schedule_date (``int``, *optional*):

Date when the message will be automatically sent. Unix time.

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 file transmission progress.

The function must take *(current, total)* as positional arguments (look at Other Parameters below for a

detailed description) and will be called back each time a new file chunk has been successfully

transmitted.

progress_args (``tuple``, *optional*):

Extra custom arguments for the progress callback function.

You can pass anything you need to be available in the progress callback scope; for example, a Message

object or a Client instance in order to edit the message with the updated progress status.

Other Parameters:

current (``int``):

The amount of bytes transmitted so far.

total (``int``):

The total 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` | ``None``: On success, the sent voice message is returned, otherwise, in case the upload

is deliberately stopped with :meth:`~Client.stop_transmission`, None is returned.

Example:

.. code-block:: python

# Send voice note by uploading from local file

app.send_voice("me", "voice.ogg")

# Add caption to the voice note

app.send_voice("me", "voice.ogg", caption="voice note")

# Set voice note duration

app.send_voice("me", "voice.ogg", duration=20)
