Proxy Authentication for Google Speech Api Credential

[swapp1990]

I am trying to configure google speech api to work in my project within the company's firewall. I have configured the SpeechSettings as following:

InputStream is = this.getClass().getResourceAsStream("/my-service-account.json");           
CredentialsProvider credentialsProvider = FixedCredentialsProvider.create(ServiceAccountCredentials.fromStream(is));
SpeechSettings.Builder builder = SpeechSettings.newBuilder();
builder.setTransportProvider(SpeechSettings.defaultTransportProvider());
builder.setCredentialsProvider(credentialsProvider);
SpeechSettings settings =  builder.build();
SpeechClient.create(settings);

Describe the issue

Using this works outside proxy network correctly and starts a speech recognize session. But it fails to transcribe anything under a proxy authenticated network and times out without giving any error. Is it possible to authenticate with the proxy settings while creating the speech client session? Thanks.

Hi, have you looked at https://blog.box.com/blog/connecting-google-vision-api-proxy/ ?

Yes, I have tried that solution but that didn't work for me.
The only solution that worked with the proxy issue was setting environment variable: GRPC_PROXY_EXP="hostname:port" in the $PATH.
