What toolboxes should I get to do speech formant analysis in real time?

12 views (last 30 days)
I want to record speech sound with a mucrophone, and have its formants analyzed and displayed in real time. Hopefully the spectrogram can be played back from the spectrogram display as well. What toolboxes should I get? Would Sig Proc by itself sufficient? Should I also get Audio toolbox?

Hello Simon,
To record speech signals using microphone, you can use the Analog Input Recorder App available with the Data Acquisition Toolbox. You can then use the Signal Analyzer App from Signal Processing Toolbox to view the recorded signal’s spectrogram, scalogram, etc and perform required analysis. I don’t think it is possible to do the analysis in real time while recording the signal.
Hope it was helpful.
