# saiTtsSetKillOnBargeIn

Enables or disables kill-on-barge-in support for a specified synthesizer.

#### Prototype

DWORD saiTtsSetKillOnBargeIn ( SAI_SYNTHESIZER_HANDLE synth H d, BOOL value )

Argument | Description
synthHd | Handle associated with a synthesizer resource.
value | One of the following values: TRUE: Kill-on-barge-in support is enabled. FALSE: Kill-on-barge-in support is disabled.

#### Return values

Return value | Description
SUCCESS |
SAIERR_INVALID_PARAMETER | One of the specified arguments is invalid.
SAIERR_UNSUPPORTED_SPEECH_PARAMETER | Speech engine does not support the specified parameter.

#### Details

When kill-on-barge-in is enabled, the synthesizer stops all active or pending speech requests when it is notified of a barge-in condition. If the recognizer and the synthesizer are in the same session, the recognizer engine can notify the synthesizer engine of barge-in detection and ask the synthesizer to immediately stop all speech requests. In both cases, the application performs the same action, except that the synthesizer is notified earlier when the recognizer and synthesizer are in the same session.

Note: In either case, SAIEVN_START_OF_SPEECH is sent to the application. The application must close the loop by calling saiNotifyBargeInToSynthesizer and specifying the proxySyncId received in SAIEVN_START_OF_SPEECH.
