Speech API gRPC Sync Request returns first words only

[Ronald Ruijs]

Hello,

When I call the Google Speech API with gRPC for sync requests, only first part of the audio data is recognized. Tested witn Google sample audio file "How old is the Brooklyn Bridge", for which only "how old" is returned. Other audio data shows the same behaviour, only first 1 or 2 words are returned. In all cases, no errors are returned, and confidence factor is also returned. 

Calling the Speech API via REST works fine for the same audio.

Please note I do not use Google's client libarries. Calls are made using plain http/2.

Any ideas are highly appreciated.

Best regards, Ronald

PS For streaming gRPC request, the same issue seems to be present, depending on audio buffer size. To be investigated later.

Hi,

I worked on some reproduction where the output was as expected. Should you still be facing the issue, could you kindly open an issue tracker for this matter? Kindly include any audio file you experienced the issue with as well as the request sent to allow us to reproduce the issue on our end.

Hi Ronald,

I can see an internal issue was created for the Speech API engineering team to further investigate this matter. You can expect future updates to be posted on the thread of the issue tracker you created.

Hi, any news on this? Certainly not via issue tracker…
