Microsoft Speech API 5.4

SPDUI_UserTraining (C/C++)

SpeechUserTraining (Automation)

SPDUI_UserTraining defines the string for displaying a speech recognition (SR) engine's User Training UI.

  
#define SPDUI_UserTraining        L"UserTraining"

It is not a SAPI 5 compliance requirement for an SR engine to implement this UI for SPDUI_UserTraining.

When to Implement

When writing a speech engine for the desktop or a graphical environment, users can train the engine either before the first use, or when recognition accuracy is poor.

Use the SR tab of Speech properties in Control Panel to change settings for all installed SAPI 5-compliant SR engines. Click Train Profile to change settings on a per-user/per-engine basis. Use Train Profile to directly access each engine's Settings UI using SPDUI_UserTraining. If the SR engine does not support the training UI (see ISpTokenUI::IsUISupported), Train Profile will be unavailable.

When to Access

The application could monitor the user's speech experience by recognition accuracy. If a user encounters too many false recognitions or recognition corrections, the application could recommend that the user perform more recognizer training.

Also, an SR engine can send a SPEI_REQUEST_UI event to the application if it determines that the user needs to perform additional recognizer training. (See also ISpRecognizer::IsUISupported and ISpRecognizer::DisplayUI.)
