Abstract
A method for providing sidetone adjustment comprises generating an audio signal representing user speech, determining a spectral distribution of the audio signal, determining a voice category from the spectral distribution of the audio signal, applying an adjustment to the audio signal based on the determined voice category to generate an adjusted audio signal, and providing audio output based on the adjusted audio signal to the user as sidetone. The adjustment to the audio signal may comprise adjustments to a plurality of frequency bands in the audio signal. The adjustments may further comprise boosting the levels of frequency bands in a high frequency speech band.
Claims20
A method for providing sidetone adjustment, the method comprising:
- receiving an audio signal representing speech of a user;
- determining a spectral distribution of the audio signal;
- determining a voice category from the spectral distribution of the audio signal;
- applying an adjustment to the audio signal, based on the determined voice category, to generate an adjusted audio signal;
- and
- providing audio output based on the adjusted audio signal to the user as sidetone.
A computing apparatus for providing sidetone adjustment, the computing apparatus comprising:
- one or more computer processors;
- and
- one or more memories storing instructions that, when executed by the one or more computer processors, configure the computing apparatus to perform operations comprising:
- receiving an audio signal representing speech of a user;
- determining a spectral distribution of the audio signal;
- determining a voice category from the spectral distribution of the audio signal;
- applying an adjustment to the audio signal, based on the determined voice category, to generate an adjusted audio signal;
- and
- providing audio output based on the adjusted audio signal to the user as sidetone.
A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by one or more computer processors of one or more computing devices, cause the one or more computing devices to perform operations for providing sidetone adjustment, the operations comprising:
- receiving an audio signal representing speech of a user;
- determining a spectral distribution of the audio signal;
- determining a voice category from the spectral distribution of the audio signal;
- applying an adjustment to the audio signal, based on the determined voice category, to generate an adjusted audio signal;
- and
- providing audio output based on the adjusted audio signal to the user as sidetone.
