Abstract

A baby crying recognizing system includes: (1) an amplifier for amplifying the sound signal; (2) a pulse generator connected with amplifier for generating a zero crossing signal which is generated by inputting the amplified signal through the amplifier into pulse generator; and a signal recognizer for receiving the zero crossing signal to get zero crossing rate of each frame pulse signal in predetermined frame number under fixed time zone and output a recognition signal under the condition of the below two conditions are satisfied: case 1, the zero crossing rate of continuous first threshold frames is in a specific range; case 2, the total zero rate of whole time zone is larger one second threshold value and less than one third threshold value.
