Voice Recognition Data Acquisition

Overview

The following code demonstrates how to call and use the existing Microsoft Speech API within LabVIEW tocreate a voice recognition data acquisition application.

 

Description

 The Speech API can be called from LabVIEW to create any speech recognition application,

in this case, data acquisition. The Speech API is part of the .NET Framework which in mostcases is already installed on computers running Windows XP or Vista OS. In general the API will

automatically “listen” for key phrases, perform voice recognition analysis on the audio stream,

and will also convert text to speech.

Steps to Implement or Execute Code

To run this example, please verify the following:

• For users running Windows XP verify that you have at minimum, the Microsoft .NET

Framework, 3.0 and the SAPI (speech API) version 5.1 (SpeechSDK51.exe).

• For users running Vista or 7, verify or download that you have the following: SAPI version

5.3.
