Bitrate/Sample Rate Differences #39

Open bitnom opened 5 years ago

bitnom commented 5 years ago

How much of an impact does the sample rate and bitrate have? My use case is that I need to perform speaker verification across multiple sample rates/codecs such as AMR and EVRC. I will of course be converting them to wav for training but since I will be performing the verification across multiple sample rates, I'm wondering if I should adapt my training set to have varying sample rates as well. Thoughts?

It's logical that lowering the sampling rate and bitrate will hurt accuracy, but how much I'm not sure off off the top of my head. I would just try it.

I think it's a good idea to adopt the training set to have multiple sampling rates.
