Resolved Is there any Noise Cancellation Feature in Vivox?

Hi, what you are describing is adjustments to our voice activity detection settings. I'd recommend checking out this article Vivox: How to: Access VAD settings.

 

Take a look at the

Logout

method in

LoginSession.cs

file in your Vivox package. You'll see a new request of type

vx_req_account_logout_t

being created, filled in, and then the request issued. You'll want to add a new method to the LoginSession class to handle setting the VAD. In that method, you'll be creating a new

vx_req_aux_set_vad_properties_t

object, setting the values to what you want based on the FAQ article, and then issuing the request.

Here's a quick example to set the Auto VAD, which I'd try first. For more information about the Auto VAD, please see the article I linked previously.

Code (CSharp):

1. public void SetAutoVad()
2. {
3.     if (_state == LoginState.LoggedIn)
4.     {
5.         var request = new vx_req_aux_set_vad_properties_t();
6.         request.account_handle = _accountHandle;
7.         request.vad_auto = 1;
8.         VxClient.Instance.BeginIssueRequest(request, null);
9.     }
10. }

 

Hello, it sounds like you have found values that work for you.

You can also try with

request.vad_auto

? This mode take a few seconds to adjust as it gathers data from the audio stream. This allows for it to dynamically adjust itself for different users rather than using a fixed value for all users.

Does this resolve your issue?

 

That sounds fine. The robotic voice should not be related to the VAD. I'll close out this thread.
