How To best decode telephonic conversation (8KHz) audio files. Is there any way other than resampling it to 16K

I want to transcribe telephonic conversation audio files(8Khz). Other that resampling it to 16K what is the best option.

I don’t think I’ve understood your question. Do you want to directly input the model with audios of 8kHz instead of resampling?

Yeah. Something like that.

You don’t need to resample as @lissyx said in here
