Microsoft Cognitive Service Speech-to-Text - Using compressed input audio data "incompatible types"

Question

I followed the example on 1 to implement STT with Java. When I just copy the code into my Spring Boot Backend, I get the following error:

java: incompatible types: com.microsoft.cognitiveservices.speech.audio.AudioStreamFormat cannot be converted to com.microsoft.cognitiveservices.speech.audio.PullAudioInputStreamCallback

What am I doing wrong here? I just copied the code from the Microsoft page

Answer 1

@Henning Weise Thanks for the question. Are you using which version of SDK? PullAudioInputStream now send wav header information to the Speech Service based on AudioStreamFormat, optionally specified when they were created. now use the supported audio input format. Any other formats will get sub-optimal recognition results or may cause other issues.

Here is the document to use audio input streams.
