Abstract
The invention relates to a method and an apparatus for tracking a fundamental frequency of a voice signal. A sampling device samples a voice signal of a test person for a predetermined period of time (S), thus obtaining sampling data of the voice signal, forms a data packet from the sampling data (S), and sends the data packet to a calculating device (S). The calculating device receives the data packet (S) and calculates a fundamental frequency of the voice signal by means of the sampling data contained in the data packet (S). The sampling device sets a timer based on the fundamental frequency calculated by the calculating device and outputs a trigger signal upon expiration of the timer (S).
