Output only. Immutable. The revision ID of the phrase matcher.

Example: locations/global/phraseMatchers/my-first-matcher@1234567
public ConversationParticipant.Types.Role RoleMatch { get; set; }
The role whose utterances the phrase matcher should be matched
against. If the role is ROLE_UNSPECIFIED it will be matched against any
