defmodule GoogleApi.Speech.V1.Model.RecognitionConfig do
  @moduledoc """
  Provides information to the recognizer that specifies how to process the
  request.

  ## Attributes

  *   `audioChannelCount` (*type:* `integer()`, *default:* `nil`) - The number of channels in the input audio data.
      ONLY set this for MULTI-CHANNEL recognition.
      Valid values for LINEAR16 and FLAC are `1`-`8`.
      Valid values for OGG_OPUS are '1'-'254'.
      Valid value for MULAW, AMR, AMR_WB and SPEEX_WITH_HEADER_BYTE is only `1`.
      If `0` or omitted, defaults to one channel (mono).
      Note: We only recognize the first channel by default.
      To perform independent recognition on each channel set
      `enable_separate_recognition_per_channel` to 'true'.
  *   `diarizationConfig` (*type:* `GoogleApi.Speech.V1.Model.SpeakerDiarizationConfig.t`, *default:* `nil`) - Config to enable speaker diarization and set additional
      parameters to make diarization better suited for your application.
      Note: When this is enabled, we send all the words from the beginning of the
      audio for the top alternative in every consecutive STREAMING responses.
      This is done in order to improve our speaker tags as our models learn to
      identify the speakers in the conversation over time.
      For non-streaming requests, the diarization results will be provided only
      in the top alternative of the FINAL SpeechRecognitionResult.
  *   `enableAutomaticPunctuation` (*type:* `boolean()`, *default:* `nil`) - If 'true', adds punctuation to recognition result hypotheses.
      This feature is only available in select languages. Setting this for
      requests in other languages has no effect at all.
      The default 'false' value does not add punctuation to result hypotheses.
      Note: This is currently offered as an experimental service, complimentary
      to all users. In the future this may be exclusively available as a
      premium feature.
  *   `enableSeparateRecognitionPerChannel` (*type:* `boolean()`, *default:* `nil`) - This needs to be set to `true` explicitly and `audio_channel_count` > 1
      to get each channel recognized separately. The recognition result will
      contain a `channel_tag` field to state which channel that result belongs
      to. If this is not true, we will only recognize the first channel. The
      request is billed cumulatively for all channels recognized:
      `audio_channel_count` multiplied by the length of the audio.
  *   `enableWordTimeOffsets` (*type:* `boolean()`, *default:* `nil`) - If `true`, the top result includes a list of words and
      the start and end time offsets (timestamps) for those words. If
      `false`, no word-level time offset information is returned. The default is
      `false`.
  *   `encoding` (*type:* `String.t`, *default:* `nil`) - Encoding of audio data sent in all `RecognitionAudio` messages.
      This field is optional for `FLAC` and `WAV` audio files and required
      for all other audio formats. For details, see AudioEncoding.
  *   `languageCode` (*type:* `String.t`, *default:* `nil`) - Required. The language of the supplied audio as a
      [BCP-47](https://www.rfc-editor.org/rfc/bcp/bcp47.txt) language tag.
      Example: "en-US".
      See [Language
      Support](https://cloud.google.com/speech-to-text/docs/languages) for a list
      of the currently supported language codes.
  *   `maxAlternatives` (*type:* `integer()`, *default:* `nil`) - Maximum number of recognition hypotheses to be returned.
      Specifically, the maximum number of `SpeechRecognitionAlternative` messages
      within each `SpeechRecognitionResult`.
      The server may return fewer than `max_alternatives`.
      Valid values are `0`-`30`. A value of `0` or `1` will return a maximum of
      one. If omitted, will return a maximum of one.
  *   `metadata` (*type:* `GoogleApi.Speech.V1.Model.RecognitionMetadata.t`, *default:* `nil`) - Metadata regarding this request.
  *   `model` (*type:* `String.t`, *default:* `nil`) - Which model to select for the given request. Select the model
      best suited to your domain to get best results. If a model is not
      explicitly specified, then we auto-select a model based on the parameters
      in the RecognitionConfig.
      <table>
        <tr>
          <td><b>Model</b></td>
          <td><b>Description</b></td>
        </tr>
        <tr>
          <td><code>command_and_search</code></td>
          <td>Best for short queries such as voice commands or voice search.</td>
        </tr>
        <tr>
          <td><code>phone_call</code></td>
          <td>Best for audio that originated from a phone call (typically
          recorded at an 8khz sampling rate).</td>
        </tr>
        <tr>
          <td><code>video</code></td>
          <td>Best for audio that originated from from video or includes multiple
              speakers. Ideally the audio is recorded at a 16khz or greater
              sampling rate. This is a premium model that costs more than the
              standard rate.</td>
        </tr>
        <tr>
          <td><code>default</code></td>
          <td>Best for audio that is not one of the specific audio models.
              For example, long-form audio. Ideally the audio is high-fidelity,
              recorded at a 16khz or greater sampling rate.</td>
        </tr>
      </table>
  *   `profanityFilter` (*type:* `boolean()`, *default:* `nil`) - If set to `true`, the server will attempt to filter out
      profanities, replacing all but the initial character in each filtered word
      with asterisks, e.g. "f***". If set to `false` or omitted, profanities
      won't be filtered out.
  *   `sampleRateHertz` (*type:* `integer()`, *default:* `nil`) - Sample rate in Hertz of the audio data sent in all
      `RecognitionAudio` messages. Valid values are: 8000-48000.
      16000 is optimal. For best results, set the sampling rate of the audio
      source to 16000 Hz. If that's not possible, use the native sample rate of
      the audio source (instead of re-sampling).
      This field is optional for FLAC and WAV audio files, but is
      required for all other audio formats. For details, see AudioEncoding.
  *   `speechContexts` (*type:* `list(GoogleApi.Speech.V1.Model.SpeechContext.t)`, *default:* `nil`) - Array of SpeechContext.
      A means to provide context to assist the speech recognition. For more
      information, see
      [speech
      adaptation](https://cloud.google.com/speech-to-text/docs/context-strength).
  *   `useEnhanced` (*type:* `boolean()`, *default:* `nil`) - Set to true to use an enhanced model for speech recognition.
      If `use_enhanced` is set to true and the `model` field is not set, then
      an appropriate enhanced model is chosen if an enhanced model exists for
      the audio.

      If `use_enhanced` is true and an enhanced version of the specified model
      does not exist, then the speech is recognized using the standard version
      of the specified model.
