Question
The autocorrelation sequence in Figure 4.11 corresponds to a strongly voiced speech. Show with an arrow which autocorrelation sample relates to the pitch period of the voiced signal. Estimate the pitch period from the graph.
Step 1
Autocorrelation is a mathematical tool used to measure the similarity between a signal and a delayed version of itself over varying time lags. For voiced speech, the autocorrelation function will exhibit peaks at intervals corresponding to the pitch period. Show more…
