The time-domain periodogram algorithm

The Time-Domain Periodogram Algorithm (TDPA) is proposed for estimating the pitch period of voiced speech sounds. After the algorithm has been presented theoretically, experimental results of the analysis of speech signals and sinusoids using the TDPA are given and the algorithm's noise performance is also evaluated. These results compare favourably with the average magnitude difference function (AMDF). The TDPA is highly suitable for implementation on a 16-bit microprocessor, since it uses no multiply operations and the computation can be performed in integer arithmetic without exceeding the dynamic range of the microprocessor. The TDPA also provides as a byproduct a well behaved estimate of signal intensity.
