public sealed class ExplicitDecodingConfig : IMessage<ExplicitDecodingConfig>, IEquatable<ExplicitDecodingConfig>, IDeepCloneable<ExplicitDecodingConfig>, IBufferMessage, IMessage
Reference documentation and code samples for the Cloud Speech-to-Text v2 API class ExplicitDecodingConfig.
Sample rate in Hertz of the audio data sent for recognition. 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).
Supported for the following encodings:
LINEAR16: Headerless 16-bit signed little-endian PCM samples.
