-///TODO: add implementation
+///Use this method to send audio files, if you want Telegram clients to display
+/// the file as a playable voice message. For this to work, your audio must be
+/// in an .ogg file encoded with OPUS (other formats may be sent as Audio or
+/// Document). On success, the sent Message is returned. Bots can currently send
+/// voice messages of up to 50 MB in size, this limit may be changed in the
+/// future.
