Currently I am using speech-to-text restful api ，the ogg container format is written by myself ，this ogg file can be played directly ,but i don't know why the microsoft engine return “Empty reply from server” , the retCode is 100 .

curl --location --request POST 'https://japaneast.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1?language=en-US' --header 'Ocp-Apim-Subscription-Key: xxx' --header 'Content-Type: audio/ogg; codecs=opus' --data-binary @'output.ogg'

you can download the file from the following link : https://drive.google.com/file/d/18bn2_lxe6VO0AP7t0Bcbp4z3uuKAriob/view?usp=sharing https://drive.google.com/file/d/1LMZh1_3PAEm8vNYkHcB6jxUge1M1wXlz/view?usp=sharing

  • Please, follow the guidelines when making a question. It's not clear, it doesn't even have a question mark. Read this: https://stackoverflow.com/help/how-to-ask – Ramon Dias Jan 14 '22 at 03:42
  • I have found the reason . According to rfc7845, In ogg container , All fields in the ID headers are REQUIRED, except for 'channel mapping table', which MUST be omitted when the channel mapping family is 0, but is REQUIRED otherwise. In my oggfile, erros due to automatic memory alignment, when Mapping Family equal 0 , still have Channel Mapping Table Filed. PS:The same file, I can get the translation result through google engine. – zpzhuang Jan 14 '22 at 12:32
