I am calculating formants for large amount of speech data using waveSurfer console, but the output formants can not be aligned with the original labels for the waveform files. I tried to change the options in the 'formant' command in snack, however, I did not solve this problem. How to solve this problem please?

Many thanks
Rachel

When using the default settings for the formant command the first formant vector will correspond to the time 0.0245s (half of the value given with -winlength), the following vectors will be spaced 0.01s. At the end of the sound the vectors will stop just before the end of the sound file, something like 0.02s-0.03s. Naturally, the behaviour at the edges presents no problem as long as you have leading and trailing silence in your files.

I can not run wavSurfer again in my PC (windows XP) machine. I got the information in the window of 'Error in startup scrip' , that is "extra characters after close-quote while compiling". There are lots of words below the above information.
I downloaded and reinstalled the software (both binary and souce code) again, but this problem is still there.
Please help me to solve this.

Many thanks

When I use the default setting for the formant command (step 0.01s and windowlength 0.049s), the length from the first formant vector to the last formant vector (including edges) are much longer than the original label length. I tried several different signals. For each one, the length from the first formant vector to the last formant vector (including edges) are more than 0.1s longer than the original label length. this is longer than leading and trailing silence in my files. What should I do please?

Thanks
Rachel
