Google Cloud Speech API returned "Quota exceeded"

Question

My desktop Python application transcribes large sets of speech samples (each speech sample duration is between 1 sec and 8 sec long) and for that I am using Google Cloud Speech API. I am aware of all the usage limitations mentioned in this page and certainly within the limits to make sure that I do not violate any of these conditions.

When I started the application for one of my set of speech samples, it was able to transcribe few of them and interrupted in the middle with this error:

googleapiclient.errors.HttpError:
<HttpError 429 when requesting 
https://speech.googleapis.com/v1beta1/speech:syncrecognize?alt=json returned 
"Quota exceeded.">

I searched on web with this error ID and found this but I could not specifically relate it to the one that I am dealing with. Are there any other limitations with Google Cloud Speech API that I should be aware of?

Any help would be highly appreciated.

You got rate limited by the Google Cloud API. Try waiting a bit and trying your request again. — Eli Sadoff
My application have made 306 requests, but the limit per 100 seconds was 500 requests. Rate limits are mentioned here — vishnu
Are you sure that your application doesn't double request or something along those lines? This is very hard to answer with just an error message. — Eli Sadoff
I am positive that application does not do that. It transcribes one speech sample at a time and waits for Google to send the response back. And then it continues with the next speech sample. — vishnu

I also encounter this problem. Try checking the quotas on your API Manager dashboard > Speech API > Quotas.

I've just found out that for a simple Asynchronous requests, my quota increased by 50 requests.
