Call analysis and voice detection level are defaulted campaign fields. Product pages also list answering-machine detection and automatic voicemail as agent-efficiency tools. None of those pages give you a percent accuracy you can put in a contract.
A live person marked as a machine is a silent failure: the agent never hears them, or a voicemail template talks to a human. Treat detection as a tuned setting with a monitoring report, not as a fact about the callee.
