The invention provides an antenatal training device and fetus-voice meter integrated machine. The machine comprises a fetal heart signal acquisition device and a fetal heart signal extraction device, wherein the fetal heart signal acquisition device is used for sending out antenatal training voice signals and acquiring heartbeat sound signals sent out from the body of a pregnant woman at an interval of the antenatal training voice signals; the fetal heart signal extraction device receives the heartbeat sound signals acquired by the fetal heart signal acquisition device and separating fetal heart signals from the heartbeat sound signals, and the separated fetal heart signals are sent to a background server to be analyzed or displayed and primarily diagnosed at the local end; the fetal heart signal acquisition device adopts a bone conduction microphone and receives the heartbeat sound signals passively. The machine can monitor the heartbeat of a fetus while performing antenatal training on the fetus, acquires the fetal heart signals through the bone conduction microphone, cannot harm human bodies due to the fact that the fetal heart signals are received passively in the whole acquisition process and is safe and high in practicability.
