Are you aware that the same exact uncompressed recording sounds different depending on context? This is known as the McGurk effect.
Very worth your two minutes if you're not yet familiar with the effect: https://www.youtube.com/watch?v=2k8fHR9jKVM

This is no different than using, for example, a probabilistic algorithm to solve some NP-hard problem in your real world software. As long as you understand the limitations, I don't see an issue with using an algorithm that has a small non-significant (for your use-case) rate of failure. I would definitely not use this to communicate with the space station, but in the right context (Google Duo, low bandwidth), it's the perfect tool.
