How to detect the silence and get separative line like below.

Hi,

I am trying to the forced alignment between a transcript and a video, however, among the utterances, there are lots of silences. How do I figure the tool to detect those silence and not get a consecutive result. In an example:

I want from:

That thereby beauty's rose might never die, => [00:00:05.880, 00:00:09.240]
But as the riper should by time decease, => [00:00:09.240, 00:00:11.920]
His tender heir might bear his memory: => [00:00:11.920, 00:00:15.280]
But thou contracted to thine own bright eyes, => [00:00:15.280, 00:00:18.800]
Feed'st thy light's flame with self-substantial fuel, => [00:00:18.800, 00:00:22.760]
Making a famine where abundance lies, => [00:00:22.760, 00:00:25.680]

But as the riper should by time decease, => [00:00:10.240, 00:00:11.920]
His tender heir might bear his memory: => [00:00:11.920, 00:00:15.280]
But thou contracted to thine own bright eyes, => [00:00:16.280, 00:00:18.800]
Feed'st thy light's flame with self-substantial fuel, => [00:00:19.800, 00:00:22.760]
Making a famine where abundance lies, => [00:00:22.760, 00:00:25.680]

Thank you in advance.

You could use another library like PyDub. PyDub has a function called detect silence or something similar. Once you have determined what timestamps of the audio are silent, you can use some Python-coder-magic to fix your alignments ;)
