I am using Matlab 2019b but still using "HelperFeatureVector2Sequence" function gives error as undefined function. Why ????

ver
at the command window prompt, do you see the Audio Toolbox listed?

Copying Moomal Tariq's comment here, instead of being an "answer":
"when i type license('inuse') it just says MATLAB ...i am using trial version"

That command lists all the toolboxes you are licensed to use. (That is different from just being installed.)
I suggest you go to the license center to see if you can figure it out from there, or contact support from the link on that page.

Hi Moomal,
This function is not on path by default. I believe it is used in a featured example in Audio Toolbox. to get access to this function, browse to the doc page of the featured example, and then click the 'Open Script' button (around the top right on the doc page). That should take you to a folder that contains the code for the example (including the function you are looking for).

Brace indexing is used because features is a cell array in the example. You will have to modify the function if you are not using cells.

I used the ''Voice Activity Detection Noise Using Deep Learning Example'', where i can find:
trainFeatureCell = helperFeatureVector2Sequence(featuresTraining',sequenceLength,sequenceOverlap);
at the beginning of the function you have:
function [sequences,sequencePerSegment] = HelperFeatureVector2Sequence(features,featureVectorsPerSequence,featureVectorOverlap)
so I'm giving to the function my featuresTraining' as the features.
The featureTraining type is double, but the script is still working, which is somenthing that I can't understand
