You know, there are illegal cell phones in prisons. If the prison folks have the ability to determine whose voice is speaking, then they can related an outgoing cell signal at the prison to a particular incarcerated person.
It would be like a wire-tap without a warrant. Do they need a warrant for someone already in prison?
It is going to be funny/ironic when the "Social Credit" system in China has voice-fingerprints of nearly every person under surveillance, so that words heard by any listening device would be admissible to analysis. They could then detect someone saying things of folks in power, both in adherence to political norms, and also in detection of fraud.
