      • getEncodingValue

        public int getEncodingValue()
         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][google.cloud.speech.v1.RecognitionConfig.AudioEncoding].
        .google.cloud.speech.v1.RecognitionConfig.AudioEncoding encoding = 1;
        Specified by:

        Returns:
        The enum numeric value on the wire for encoding.

      • getEncoding

        public RecognitionConfig.AudioEncoding getEncoding()
         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

      • getSampleRateHertz

        public int getSampleRateHertz()
         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][google.cloud.speech.v1.RecognitionConfig.AudioEncoding].
        int32 sample_rate_hertz = 2;
        Specified by:

      • getAudioChannelCount

        public int getAudioChannelCount()
         The number of channels in the input audio data.
 ONLY set this for MULTI-CHANNEL recognition.
 Valid values for LINEAR16, OGG_OPUS and FLAC are `1`-`8`.
 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'.
        int32 audio_channel_count = 7;
        Specified by:
        getAudioChannelCount in interface RecognitionConfigOrBuilder

      • getEnableSeparateRecognitionPerChannel

        public boolean getEnableSeparateRecognitionPerChannel()
         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.
        bool enable_separate_recognition_per_channel = 12;
        Specified by:
        getEnableSeparateRecognitionPerChannel in interface RecognitionConfigOrBuilder
