Required. The name of the Recognizer to use during recognition. The
expected format is
`projects/{project}/locations/{location}/recognizers/{recognizer}`. The
{recognizer} segment may be set to `_` to use an empty implicit Recognizer.

<code>
string recognizer = 3 [(.google.api.field_behavior) = REQUIRED, (.google.api.resource_reference) = { ... }

@return The bytes for recognizer.
