I am using simulink audio tool box to record an audio.
I am starting this simulink code using my matlab code.(sim("*simulink file name*")).
But i want this simulink file to run for 15 seconds so the .wav file output from the simulink code can be read by the matlab code.

So I'm assuming you mean that you want the Simulink model to run for 15 seconds of real time. Otherwise if you just want it to run for 15 seconds of simulated elapsed time you could just set you stop time to 15 seconds.
To make it run for 15 seconds of real time you can use the Simulation Pacing Option. To get to this setting click on the drop down below the Run button. There you can check the box for "Enable pacing to slow down simulation, and set the slider for Simulation timer per wall clock second to 1. With those settings, if you set the stop time of the simulation to 15 seconds, the real elapsed time will also be 15 seconds.

audiorecorder() is useful for capturing a specific amount of audio data.

This should work:
sim(modelname, 15)

If the audio IO blocks are used (e,g audio Device Reader, Writer...), then the model will run in realtime with no required changes from the user. The IO blocks will take care of blocking execution.
