One solution is Izotope RX4, which has the capability to detect similar sounds in an audio recording. While it hasn't been specifically tested on voice detection, it could potentially work for this purpose. However, it requires clean samples within the same recording, and the demo version only runs for one month.
Another option is Dragon Dictate, a dictation app that allows for discrete dictation on iOS and macOS devices. This could potentially be used to identify human voice, though the details on its capabilities for this specific task are unclear from the information given.
There are also AI-based voice detection tools available, such as the one mentioned that analyzes audio clips and provides data on the proportion of human versus AI-generated voices. However, the pricing model for this type of tool may be prohibitive for one-time users.
