Try this: http://www.mathworks.com/help/techdoc/ref/audiorecorder.html. If you want to record analog data from your soundcard, you should also look at Data Acquisition Toolbox!

thank you for helping ;
in Data Acquisition Toolbox can i play recorded sound.

You would be able to output sound to a device, but DAT does not itself provide routines to read recorded sounds.

With the toolbox you can configure data acquisition hardware and read data into MATLAB and Simulink® for immediate analysis. You can also send out data over analog and digital output channels provided by data acquisition hardware.

Depends what you mean by "same time." There is going to be a few milliseconds of latency. I would look at the MATLAB based port audio implementations. There are playrec and pa-wavplay (I am not sure i the latter handles input). My preference is for the audio part of the psychtoolbox http://docs.psychtoolbox.org/PsychPortAudio

You just might be able to continue using imageInputLayer, but instead of an image of a spectrogram, you would pass it the array of specs data

From my data fucntion it can be seen that am passing the array of specs and labels but still am not getting acurate results

I work at MathWorks and I have just noticed this so I thought I'd drop a note.
I understad from your question that you were looking to process the acquired audio live (aka in "real time", or "in the loop") using a standard sound card. In all such situations we recommend looking first at audioDeviceReader and audioDeviceWriter in Audio Toolbox, which were specifically designed with that use case in mind.
The doc page below should help you get started and it includes a few links to additional resources:https://www.mathworks.com/help/audio/gs/audio-input-and-audio-output.html
Another useful page full with code examples and explanations can be found below:https://www.mathworks.com/help/audio/gs/real-time-audio-in-matlab.html
Thanks and good luck with your project.
