VoiceNET.Library 1.0.3

Introduce

VoiceNET Library makes it easy and fast to create Voice Command Control functionality through Label Prediction. It helps develop software voice control in real-time. It free supports online and offline use. This is a community development project to help people access voice recognition technology more easily.

It's a research project from the FPT Edu Research Festival 2021 contest.

Installation

Once you have an app, you can install the VoiceNET Library NuGet package from the .NET Core CLI using:

dotnet add package VoiceNET.Library

or from the NuGet Package Manager:

Install-Package VoiceNET.Library

Quickstart

Real-time

Drag and drop into the Windows Forms interface:

• Picturebox: pbSpectrogram and picTake with Width=400
• Combobox: cbDevice
• Label: lbResult
• Timer: tmLisener (Interval 100, Enabled=True) and tmDisposeRam (Interval 1, Enabled=True)

In Form_Load

 VBuilder.getDevice(cbDevice);

 VBuilder.setVolume(80);

 VBuilder.ModelPath("<your_model_path>");

 if(VBuilder.loadModel())

    //do something after Load Model

 else

   //do something if fail

cbDevice_SelectedIndexChanged

StartListening();

Create two private void: StartListening() and DisposeImage().

StartListening()

DisposeImage();

VBuilder.StartListening( cbDevice );

DisposeImage()

pbSpectrogram.Image?.Dispose();

pbSpectrogram.Image = null;

tmDisposeRam_Tick

DisposeImage();

pbSpectrogram.Image = VBuilder.ListenTimer(pbSpectrogram.Width);

tmLisener_Tick

  if(VBuilder.requestDisposeListening)
            {

                picTake.Image = VBuilder.getImageTaken(pbSpectrogram);

                lbResult.Text = VBuilder.Result();

                StartListening(); //Renew Lisener

                VBuilder.requestDisposeListening = false;

            }

            else

            {

                VBuilder.reduceNoiseAndCapture(pbSpectrogram);

            }

Recording

Drag and drop into the Windows Forms interface:

• Button: btnRecord, btnStop
• Label: lbResult

Form_Load

VBuilder.ModelPath("<your_model_path>");

 if(VBuilder.loadModel())

    //do something after Load Model

 else

   //do something if fail

btnRecord_Click

VBuilder.Record();

btnStop.Enabled = true;

btnRecord.Enabled = false;

btnStop

VBuilder.Stop();

lbResult.Text = VBuilder.Result(true);

btnRecord.Enabled = true;

btnStop.Enabled = false;

Web ASP.NET MVC

See the example in VoiceNET.Lib.Demo.ASP.NET for more how to use it.

How to create a Model?

Use the included MicBuilder program to build an MLModel.zip file for your Dataset.
