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.
Optional. Number of channels present in the audio data sent for
recognition. Note that this field is marked as OPTIONAL for backward
compatibility reasons. It is (and has always been) effectively REQUIRED.
Optional. Sample rate in Hertz of the audio data sent for recognition.
Valid values are: 8000-48000, and 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 resampling).
Note that this field is marked as OPTIONAL for backward compatibility
reasons. It is (and has always been) effectively REQUIRED.
