Hello @markuseisl,
I found out that a problem is because of latency since I have 50 Mbit/s download and 10 Mbit/s so my computer had a problem with uploading recording of my voice to API.
After testing it a little, free version of Google API for Speach to Text has it limits:
“message”: “Quota exceeded for quota metric ‘Requests’ and limit ‘Requests per minute’ of service ‘speech.googleapis.com’ for consumer ‘project_number:292824132082’.”,
I will try later and post my results back.
Cheers,
Dino
