- Compute the average amplitude for each of fifty 0.1 second snippets of the five seconds
- Iterate from each end of the clip until a given number of snippets have amplitude greater than some threshold.
- Tune (a) the number of high-amplitude snippets required to trigger the beginning and end of the audio and (b) the threshold amplitude to achieve your desired accuracy.

Hello I have a tricky situation ?
- I need to develop a code which can record user voice and play back?-> the code is ready and running fine.
- Now the real problem, I need to identify the position of the spoken word.
In detail: say for example i have defined 5 seconds time duration for recording. during this time i speak a sentence "how are you ", say this whole sentence completes in 3 seconds (ideally) and the remaining 2 seconds are vacant and there are no information available.
Now, I have plotted the recorded file also. now i need to determine the position of either of the three words, that is the location of the words in whole 5 seconds duration?
could you please help me in determining code?

Assuming that the sound amplitude is lower when the words are not being spoken, the following solution should roughly give you a start and end time:
