Optional. An optional [KMS key
name](https://cloud.google.com/kms/docs/resource-hierarchy#keys) that if
present, will be used to encrypt Speech-to-Text resources at-rest. Updating
this key will not encrypt existing resources using this key; only new
resources will be encrypted using this key. The expected format is
`projects/{project}/locations/{location}/keyRings/{key_ring}/cryptoKeys/{crypto_key}`.
