Google Speech API Call

Question

I am trying to use Google Speech API v1 in .net and facing a challange in making a call.

Below is my code.

Dim userSpeech = Google.Cloud.Speech.V1.SpeechClient.Create
Dim response = userSpeech.Recognize(New RecognitionConfig, RecognitionAudio.FromFile(filePath))
For Each result In response.Results
    For Each alternative In result.Alternatives
         Console.WriteLine(alternative.Transcript)
    Next
Next

I never reach line of first FOR. I also don't get any error. The API is enabled. Google Cloud Credentials are set as environment variables. So, no problem there.

Then I tried in C# as below. But I get exact same result i.e. I don't get to foreach line.

var speech = SpeechClient.Create();
var response = speech.Recognize(new RecognitionConfig()
               {
                    Encoding = RecognitionConfig.Types.AudioEncoding.Linear16,
                    SampleRateHertz = 16000,
                    LanguageCode = "en",
                }, RecognitionAudio.FromFile("audio.raw"));


 textBox1.Text = "";

 foreach (var result in response.Results)
 {
        foreach (var alternative in result.Alternatives)
        {
               textBox1.Text = textBox1.Text + " " + alternative.Transcript;
         }
 }

Other API calls in the same application works e.g. language detection.

Any help will be highlight appreciated.

Thanks in advance.

What do you mean you don't reach it? Is there an exception being thrown or is the `Recognize` hanging and not returning? — Alexander Higgins, Jul 15 '17 at 19:57
Also have you Installed the Google Cloud SDK and authenticated by running the following command: `gcloud auth application-default login` — Alexander Higgins, Jul 15 '17 at 19:59

Make sure you have Installed the Google Cloud SDK and authenticated by running the following command:

Thanks Alexander. No, I haven't installed Google Cloud SDK yet. Thought NL APIs are working well so speech APIs would work too. Nevertheless, I'll install the SDK. Thanks again, Alexander. – Sukhi Jul 17 '17 at 06:26
Glad to help. You can mark this answer correct so others with the same issue know how you fixed it. – Alexander Higgins Jul 17 '17 at 06:27
Hi Alexander. Yes, I would do that. I am trying to install Google SDK since yesterday but there's a problem. I tried with both interactive and non-interactive installers. Give me a day or two and I'll mark your answer as correct. – Sukhi Jul 17 '17 at 16:41
