32kbps is probably a bit low, unless you add a bandpass filter, drop it to mono and reduce the bit depth.

I’d drop it to mono, drop the bit depth to 16 at most, possibly as low as 8bit.
Drop the sample rate, you’re capturing speech, so a 20kHz sample rate will halve the file size and preserve all the important frequency information.

After all that you can probably export at 16kbit….
