Provides information to the recognizer that specifies how to process the request.

Attributes

• enableWordTimeOffsets (Boolean): Optional 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`. Defaults to: null.

• encoding (String): Required Encoding of audio data sent in all `RecognitionAudio` messages. Defaults to: null.

  • Enum - one of [ENCODING_UNSPECIFIED, LINEAR16, FLAC, MULAW, AMR, AMR_WB, OGG_OPUS, SPEEX_WITH_HEADER_BYTE]
• languageCode (String): Required The language of the supplied audio as a BCP-47 language tag. Example: "en-US". See Language Support for a list of the currently supported language codes. Defaults to: null.
• maxAlternatives (Integer): Optional 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. Defaults to: null.
• profanityFilter (Boolean): Optional 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. Defaults to: null.
• sampleRateHertz (Integer): Required 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). Defaults to: null.
• speechContexts (List[SpeechContext]): Optional A means to provide context to assist the speech recognition. Defaults to: null.
