I tried this on M5Stack Atom Echo Smart Speaker. The sound is very muffled. Is there anyway to tune the output?

Yeah, that's to be expected. It was written in the late 70s for <1MHz, 8-bit CPUs with 8KB or less RAM and a 1-bit speaker output, so it's not going to win any awards for speech quality. It's still amazing what they did, though!
