public RecognitionConfig DefaultRecognitionConfig { get; set; }
Default configuration to use for requests with this Recognizer.
This can be overwritten by inline configuration in the
[RecognizeRequest.config][google.cloud.speech.v2.RecognizeRequest.config]
field.
Output only. This checksum is computed by the server based on the value of
other fields. This may be sent on update, undelete, and delete requests to
ensure the client has an up-to-date value before proceeding.
Output only. The KMS key
name with which
the Recognizer is encrypted. The expected format is
projects/{project}/locations/{location}/keyRings/{key_ring}/cryptoKeys/{crypto_key}.
Output only. The KMS key version
name
with which the Recognizer is encrypted. The expected format is
projects/{project}/locations/{location}/keyRings/{key_ring}/cryptoKeys/{crypto_key}/cryptoKeyVersions/{crypto_key_version}.
Optional. This field is now deprecated. Prefer the
[language_codes][google.cloud.speech.v2.RecognitionConfig.language_codes]
field in the
[RecognitionConfig][google.cloud.speech.v2.RecognitionConfig] message.
The language of the supplied audio as a
BCP-47 language tag.
If additional languages are provided, recognition result will contain
recognition in the most likely language detected. The recognition result
will include the language tag of the language detected in the audio.
When you create or update a Recognizer, these values are
stored in normalized BCP-47 form. For example, "en-us" is stored as
"en-US".
Optional. This field is now deprecated. Prefer the
[model][google.cloud.speech.v2.RecognitionConfig.model] field in the
[RecognitionConfig][google.cloud.speech.v2.RecognitionConfig] message.
Which model to use for recognition requests. Select the model best suited
to your domain to get best results.
