Voice Input Device

To be able to send voice commands, the client first sends a RegisterVoiceInputDeviceMessage.

syntax = "proto2";

import "ProtocolMessage.proto";
import "VoiceInputDeviceDescriptor.proto";

extend ProtocolMessage {
  optional RegisterVoiceInputDeviceMessage registerVoiceInputDeviceMessage = 33;
}

message RegisterVoiceInputDeviceMessage {
  optional VoiceInputDeviceDescriptor deviceDescriptor = 1;
}

syntax = "proto2";

import "AudioFormatSettings.proto";

message VoiceInputDeviceDescriptor {
  optional AudioFormatSettings defaultFormat = 1;
  repeated AudioFormatSettings supportedFormats = 2;
}

syntax = "proto2";

message AudioFormatSettings {
  optional bytes formatSettingsPlistData = 1;
}
