No, the Womb Music Belly Speaker system is a speaker designed to allow you to play music, your voices, etc to your baby.Wusic also makes the Womb Music Heartbeat Monitor which works similar to the fetal doppler your doctor uses to listen to the baby. The Heartbeat Monitor sold by Wusic allows you to hear your baby's heartbeat and other sounds while still in mother's belly.But the Womb Music Belly Speaker system doesn't listen to the baby, it only plays sounds to the baby.
