//
// The `FLAC` and `WAV` audio file formats include a header that describes the
// included audio content. You can request recognition for `WAV` files that
// contain either `LINEAR16` or `MULAW` encoded audio.
// If you send `FLAC` or `WAV` audio file format in
// your request, you do not need to specify an `AudioEncoding`; the audio
// encoding format is determined from the file header. If you specify
// an `AudioEncoding` when you send  send `FLAC` or `WAV` audio, the
// encoding configuration must match the encoding described in the audio
// header; otherwise the request returns an
// [google.rpc.Code.INVALID_ARGUMENT][google.rpc.Code.INVALID_ARGUMENT] error code.

//
// 4. results { alternatives { transcript: "to be or not to be"
//                             confidence: 0.92 }
