# `ExGram.Model.Voice`
[🔗](https://github.com/rockneurotiko/ex_gram/blob/0.64.0/lib/ex_gram.ex#L3897)

This object represents a voice note.

Check the [documentation of this model on Telegram Bot API](https://core.telegram.org/bots/api#voice)

- `file_id`: Identifier for this file, which can be used to download or reuse the file
- `file_unique_id`: Unique identifier for this file, which is supposed to be the same over time and for different bots. Can't be used to download or reuse the file.
- `duration`: Duration of the audio in seconds as defined by the sender
- `mime_type (optional)`: Optional. MIME type of the file as defined by the sender
- `file_size (optional)`: Optional. File size in bytes. It can be bigger than 2^31 and some programming languages may have difficulty/silent defects in interpreting it. But it has at most 52 significant bits, so a signed 64-bit integer or double-precision float type are safe for storing this value.

# `t`

```elixir
@type t() :: %ExGram.Model.Voice{
  duration: integer(),
  file_id: String.t(),
  file_size: integer() | nil,
  file_unique_id: String.t(),
  mime_type: String.t() | nil
}
```
