Format exception when returning the result from RecognizeOnceAsync

Describe the bug I followed this quickstart to enroll my voice and check my voice afterward in another audio stream : https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/get-started-speaker-recognition?tabs=script&pivots=programming-language-csharp. I used the text-independant examples. I just changed the locale for the CreateProfileAsync method, I used fr-FR.

await client.CreateProfileAsync(VoiceProfileType.TextIndependentVerification, "fr-FR")

The enrollment seems to be ok, but when I try to recognize my voice with the RecognizeOnceAsync method, I get an InvalidFormatException when the result is fetched from the web service (see thr stack trace below for more info). The error occurs when the Convert.ToDouble() is called.

To Reproduce Use the text-independant example from the link with fr-FR locale for the profil.

Expected behavior No exception thrown

Hi all,

I resolved the issue in the end. The problem was due to the difference in culture formats between the speech configuration (or cognitive services) and the local machine (mine). As I use a machine which formats strings in the “fr-fr” format, doubles in strings are probably used with “,” and not “.” as in “en-us”. The below line of code resolved the issue (changing the system format to the right one):

System.Threading.Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.GetCultureInfo("en-us");

Thanks for your will to help @glecaros!
