	abstract = {We present a system for online extraction of the fundamental frequency and the first four formant frequencies from a speech signal. To evaluate the performance of the extraction a resynthesis of the speech signal is performed. The resynthesis is based on the extracted frequencies and the energy of the input signal at the formant locations. The extraction of the fundamental frequency and the formants is robust against room echoes and interfering noise. To improve the robustness against background noise a noise reduction was implemented. Tests in three rooms of different size at varying distances to the system (up to 8 m yielding an SNR of approx. 0 dB) were performed.},
