| Interface | Description | 
|---|---|
| AcousticModel.Status | The current status of the custom acoustic model: * `pending` indicates that the model was created but is waiting
 either for training data to be added or for the service to finish analyzing added data. | 
| AddAudioOptions.ContainedContentType | For an archive-type resource, specifies the format of the audio files contained in the archive file. | 
| AddAudioOptions.ContentType | The type of the input: application/zip, application/gzip, audio/basic, audio/flac, audio/l16, audio/mp3,
 audio/mpeg, audio/mulaw, audio/ogg, audio/ogg;codecs=opus, audio/ogg;codecs=vorbis, audio/wav, audio/webm,
 audio/webm;codecs=opus, or audio/webm;codecs=vorbis. | 
| AudioDetails.Compression | **For an archive-type resource,** the format of the compressed archive: * `zip` for a **.zip** file * `gzip` for a
 **.tar.gz** file Omitted for an audio-type resource. | 
| AudioDetails.Type | The type of the audio resource: * `audio` for an individual audio file * `archive` for an archive (**.zip** or
 **.tar.gz**) file that contains audio files. | 
| AudioListing.Status | **For an audio-type resource,** the status of the resource: * `ok` indicates that the service has successfully
 analyzed the audio data. | 
| AudioResource.Status | The status of the audio resource: * `ok` indicates that the service has successfully analyzed the audio data. | 
| Corpus.Status | The status of the corpus: * `analyzed` indicates that the service has successfully analyzed the corpus; the custom
 model can be trained with data from the corpus. | 
| CreateAcousticModelOptions.BaseModelName | The name of the base language model that is to be customized by the new custom acoustic model. | 
| CreateJobOptions.ContentType | The type of the input: audio/basic, audio/flac, audio/l16, audio/mp3, audio/mpeg, audio/mulaw, audio/ogg,
 audio/ogg;codecs=opus, audio/ogg;codecs=vorbis, audio/wav, audio/webm, audio/webm;codecs=opus, or
 audio/webm;codecs=vorbis. | 
| CreateJobOptions.Events | If the job includes a callback URL, a comma-separated list of notification events to which to subscribe. | 
| CreateJobOptions.Model | The identifier of the model that is to be used for the recognition request or, for the **Create a session** method,
 with the new session. | 
| CreateLanguageModelOptions.BaseModelName | The name of the base language model that is to be customized by the new custom language model. | 
| CreateSessionOptions.Model | The identifier of the model to be used by the new session. | 
| GetModelOptions.ModelId | The identifier of the model in the form of its name from the output of the **Get models** method. | 
| LanguageModel.Status | The current status of the custom language model: * `pending` indicates that the model was created but is waiting
 either for training data to be added or for the service to finish analyzing added data. | 
| ListWordsOptions.Sort | Indicates the order in which the words are to be listed, `alphabetical` or by `count`. | 
| ListWordsOptions.WordType | The type of words to be listed from the custom language model's words resource: * `all` (the default) shows all
 words. | 
| MultipartRecognition.PartContentType | The audio format (MIME type) of the audio in the following parts:
 * `audio/basic` (Use only with narrowband models.)
 * `audio/flac`
 * `audio/l16` (Specify the sampling rate (`rate`) and optionally the number of channels (`channels`) and
 endianness (`endianness`) of the audio.)
 * `audio/mp3`
 * `audio/mpeg`
 * `audio/mulaw` (Specify the sampling rate of the audio.)
 * `audio/ogg` (The service automatically detects the codec of the input audio.)
 * `audio/ogg;codecs=opus`
 * `audio/ogg;codecs=vorbis`
 * `audio/wav` (Provide audio with a maximum of nine channels.)
 * `audio/webm` (The service automatically detects the codec of the input audio.)
 * `audio/webm;codecs=opus`
 * `audio/webm;codecs=vorbis`
 All data parts must have the same audio format. | 
| RecognitionJob.Status | The current status of the job: * `waiting`: The service is preparing the job for processing. | 
| RecognizeOptions.ContentType | The type of the input: audio/basic, audio/flac, audio/l16, audio/mp3, audio/mpeg, audio/mulaw, audio/ogg,
 audio/ogg;codecs=opus, audio/ogg;codecs=vorbis, audio/wav, audio/webm, audio/webm;codecs=opus,
 audio/webm;codecs=vorbis, or multipart/form-data. | 
| RecognizeOptions.Model | The identifier of the model to be used for the recognition request. | 
| RegisterStatus.Status | The current status of the job: * `created` if the callback URL was successfully white-listed as a result of the
 call. | 
| TrainLanguageModelOptions.WordTypeToAdd | The type of words from the custom language model's words resource on which to train the model: * `all` (the
 default) trains the model on all new words, regardless of whether they were extracted from corpora or were added or
 modified by the user. |
