VoiceNET.Library 1.0.1

Introduce

The VoiceNET Library makes it easy to integrate Voice Command Control functionality into your programs based on Label Prediction. Voice Command Control commands in the library are fixed based on a pre-assigned label. This is 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()

pbSpectrogram.Image?.Dispose();
pbSpectrogram.Image = null;
VBuilder.StartListening( cbDevice);

DisposeImage()

pbSpectrogram.Image?.Dispose();

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;

How to create a Model?

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