public sealed class TranslateSpeechConfig : IMessage<TranslateSpeechConfig>, IEquatable<TranslateSpeechConfig>, IDeepCloneable<TranslateSpeechConfig>, IBufferMessage, IMessage
Reference documentation and code samples for the Media Translation v1beta1 API class TranslateSpeechConfig.
Provides information to the speech translation that specifies how to process
the request.
Required. Encoding of audio data.
Supported formats:
linear16
Uncompressed 16-bit signed little-endian samples (Linear PCM).
flac
flac (Free Lossless Audio Codec) is the recommended encoding
because it is lossless--therefore recognition is not compromised--and
requires only about half the bandwidth of linear16.
mulaw
8-bit samples that compand 14-bit audio samples using G.711 PCMU/mu-law.
amr
Adaptive Multi-Rate Narrowband codec. sample_rate_hertz must be 8000.
amr-wb
Adaptive Multi-Rate Wideband codec. sample_rate_hertz must be 16000.
ogg-opus
Opus encoded audio frames in Ogg
container. sample_rate_hertz must be one of 8000, 12000, 16000, 24000,
or 48000.
mp3
MP3 audio. Support all standard MP3 bitrates (which range from 32-320
kbps). When using this encoding, sample_rate_hertz has to match the
sample rate of the file being used.
Optional. google-provided-model/video and
google-provided-model/enhanced-phone-call are premium models.
google-provided-model/phone-call is not premium model.
Optional. Sample rate in Hertz of the audio data. 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).
