Speech Recognition

You give this node a list of strings (value with separator or spread) and it outputs the word you said when it is recognized.

You need to download Microsoft SAPI 5.1 for this plugin to work (The file to download is SpeechSDK51.exe).

Download SAPI 5.1

Download Speech Node v1.0

Two help patches in the zip, and source code is in vvvv svn

To make sure the node works you can look in the node Inspektor (Status pin should say: OK).

If it doesn’t please send me a message with the error.

If you have this error message:

Error: Retrieving the COM class factory for component with CLSID {47206204-5ECA-11D2-960F-00C04F8EE628} failed due to the following error: 80040154.

Please try the following command (Using your own common files folder if your windows in not in english).

regsvr32 “C:\Program Files\Common Files\Microsoft Shared\Speech\sapi.dll”
