esp32_cloudspeech's Issues

while (!client.available()); infinite loop

Hi,
I modified your project by adding support for one of the two microphones that are present in the Esp32 A1S-Audio board.
After connecting with the function: client.connect (server, 443))
esp32 gets stuck in function:
while (! client.available ());

connection failed

hello. I am trying to connect to the speech.googleapis.com platform. I have activated text to speech and have under API's and services on the cloud console an API key and a service account key for Speech2text. When i start the program it connects to the internet and then gives connection failed. I am not sure where to look. Is this service still working ?

Which version esp32 support

Hello . CAN you please tell us which version of esp32 support for INMP441

Is This Service Still Working?

I'm really excited about your work on this project.

However, the project is not returning any result in the serial monitor. I have generated the API key and all other credentials.

Can you please verify that it is still working through Google APIs?

Thank you!
