OnClientSpeechDetected Property

Artigo
07/05/2006

Gets or sets the name of a client-side function that is called when the platform detects user speech. Read/write.

Usage

ASP.NET markup:	`<speech:Reco OnClientSpeechDetected="..." />`
Get value:	`String = Reco.OnClientSpeechDetected;`
Set value:	`Reco.OnClientSpeechDetected = String;`
Data type:	String
Required:	No

Remarks

Recognition engines may raise the onspeechdetected event at any point between the first detection of sound in an utterance and the return of recognition results. If a DialogPrompt is playing, the onspeechdetected event raises a client onbargein event.

If a Dtmf object is active when the OnClientSpeechDetected function is called, the time-outs of the Dtmf object will be disabled.

The value of the OnClientSpeechDetected property is the name of this custom client-side script function, without parameters or parentheses. The client-side dialog manager calls this function, using the following syntax, when the client onspeechdetected event is detected.

The script block that contains this function should be placed before the control that calls the function. For more information, see "Placement of Script Blocks" in Authoring Notes.

function FunctionName ()
{
     // Client-side code referenced by Reco.OnClientSpeechDetected
}
