Auto Detect language from list of Language Configs is giving result only in the last element of the Source Language Configuration List

arvind prajapati 5

I'm using Azure Speech to Text SDK version 1.21 in Golang. Here I'm adding a feature of Auto-detect language for the audio file using

speech.NewAutoDetectSourceLanguageConfigFromLanguageConfigs(sourceLanguageConfigs)

I'm giving a list of Source Language Configurations for multiple languages including a configuration for a Custom Model with an endpoint.

This feature gives a wrong result. It returns transcribed text using the last element of the Language Configuration List. It's not identifying the correct language. I've checked it multiple times by reordering the list and I'm getting the transcribed text in the last source language config only.

Why is it happening, can anyone help with it?

@arvind prajapati I see another user raised an issue earlier on the GO SDK repo. As per the comments on the issue, after creating the config, the config needs to be passed to speech.NewSpeechRecognizerFomAutoDetectSourceLangConfig instead of speech.NewSpeechRecognizerFromConfig

The implementation of the above is here. You might want to raise an issue with the SDK team if you still see an issue with the feature. Thanks!!

@romungi-MSFT Thanks for the response. I'm using the same method as you mentioned. I think I have to raise an issue on the SDK.
