Dear fellow researchers,

I have found that F0 values of the same speech file estimated by Praat keeps changing AFTER ‘Publish resynthesis’. This does not make sense but it is true. I have just clicked the ‘Publish resynthesis’ then estimated F0 values by ‘To Pitch: 0, 75, 600 ‘ two times.

As you can see in the attachment, the F0 values are slightly different in the beginning and in the ending portion of the same segment. I just did the same procedure 2 times for the same speech file.

I have to explain this in my research paper but I do not know why and how this can happen.

I am using version 6.1.11.

Would you help me?
