ACX_KEYWORDSPOTTER_CONFIG structure (acxelements.h)

  • Article

The ACX_KEYWORDSPOTTER_CONFIG structure is used to define the acx keyword spotter configuration.

Syntax

typedef struct _ACX_KEYWORDSPOTTER_CONFIG {
  ULONG                         Size;
  ULONG                         Id;
  const GUID                    *Name;
  ULONG                         Flags;
  const GUID                    *Pattern;
  PACX_KEYWORDSPOTTER_CALLBACKS Callbacks;
} ACX_KEYWORDSPOTTER_CONFIG, *PACX_KEYWORDSPOTTER_CONFIG;

Members

Size

The length, in bytes, of this structure.

Id

A number that represents the element ID.

Name

A pointer to a GUID that represents the name of the element. Can be used for debugging and will default to GUID_NULL if not provided.

Flags

Acx keyword spotter configuration flags defined by the ACX_KEYWORDSPOTTER_CONFIG_FLAGS enum. No flag bits are currently defined. Set this member to zero - AcxKeywordSpotterConfigNoFlags.

Pattern

The keyword spotter pattern format, expressed as a GUID.

Callbacks

The ACX_KEYWORDSPOTTER_CALLBACKS structure that identifies the driver callbacks for the keyword spotter operations.

Remarks

Example

Example usage is shown below.

    ACX_KEYWORDSPOTTER_CONFIG       keywordSpotterCfg;
    PCODEC_KEYWORDSPOTTER_CONTEXT   keywordSpotterCtx;
    ACX_PNPEVENT_CONFIG             keywordEventCfg;
    ACXPNPEVENT                     keywordEvent;

    ACX_KEYWORDSPOTTER_CALLBACKS_INIT(&keywordSpotterCallbacks);
    keywordSpotterCallbacks.EvtAcxKeywordSpotterRetrieveArm = CodecC_EvtAcxKeywordSpotterRetrieveArm;
    keywordSpotterCallbacks.EvtAcxKeywordSpotterAssignArm = CodecC_EvtAcxKeywordSpotterAssignArm;
    keywordSpotterCallbacks.EvtAcxKeywordSpotterAssignPatterns = CodecC_EvtAcxKeywordSpotterAssignPatterns;
    keywordSpotterCallbacks.EvtAcxKeywordSpotterAssignReset = CodecC_EvtAcxKeywordSpotterAssignReset;
    
    ACX_KEYWORDSPOTTER_CONFIG_INIT(&keywordSpotterCfg);
    keywordSpotterCfg.Pattern = &CONTOSO_KEYWORDCONFIGURATION_IDENTIFIER2;
    keywordSpotterCfg.Callbacks = &keywordSpotterCallbacks;
