Maybe you meant to name the variable returned by getaudiodata "mySpeech" instead of "y":
% y = getaudiodata(recObj);
mySpeech = getaudiodata(recObj);

For frequency content you can use fft or see this for some options: https://www.mathworks.com/matlabcentral/answers/160059-finding-the-frequency-value-of-a-signal
For magnitude you can use abs(mySpeech) or mean(abs(mySpeech)).

Hi Jane,
It is my understanding that the variable passed in the "fft" function is not of correct datatype. "fft" functions expects datatypes of either double or single or int8 or int16 or int32 or uint8 or uint16 or uint32 or logical type.
Note - It is not clear what value mySpeech variable contains.
Please refer to the following MathWorks documentation for more information on the “fft” function:
I hope this helps!

Binaya
