1. A method for identifying presence of speech associated with a mobile device, the method comprising:
- obtaining a plurality of audio samples from the mobile device while the mobile device operates in a mode distinct from a voice call operating mode;
generating spectrogram data from the plurality of audio samples; and
determining whether the plurality of audio samples include information indicative of speech by classifying the spectrogram data.

22. A system for detecting presence of speech in an area associated with a mobile device, the system comprising:
-
sampling means for obtaining a plurality of audio samples from the area associated with the mobile device while the mobile device operates in a mode distinct from a voice call operating mode; spectrogram means, communicatively coupled to the sampling means, for generating a spectrogram comprising spectral density data corresponding to the plurality of audio samples; and classifier means, communicatively coupled to the spectrogram means, for determining whether the plurality of audio samples include information indicative of speech by classifying the spectral density data of the spectrogram. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
