1. A method comprising:

  • determining a test audio signal that includes a user voice sample and at least one distractor;

    applying noise suppression to the test audio signal based at least in part on first noise suppression parameters to obtain a first noise-suppressed audio signal;

    causing the first noise-suppressed audio signal to be output to a speaker;

    applying noise suppression to the test audio signal based at least in part on second noise suppression parameters to obtain a second noise-suppressed audio signal;

    causing the second noise-suppressed audio signal to be output to the speaker;

    obtaining an indication of a user preference of the first noise-suppressed audio signal or the second noise suppressed audio signal; and

    determining user-specific noise suppression parameters based at least in part on the first noise suppression parameters or the second noise suppression parameters, or a combination thereof, depending on the indication of the user preference of the first noise-suppressed signal or the second noise-suppressed signal, wherein the user-specific noise suppression parameters are configured to suppress noise when a voice-related feature of the electronic device is in use.
