Abstract

The application discloses a multi-user unlocking method and apparatus, and relates to the field of mobile terminals, where the method includes: receiving, by a terminal device, an input speech signal, and obtaining sound feature parameters of the speech signal; logging into a primary user account upon determining that the sound feature parameters are consistent with primary user sound feature parameters pre-stored by the terminal device; and logging into a guest account upon determining that the sound feature parameters are not consistent with the primary user sound feature parameters pre-stored by the terminal device.

Claims

1. A multi-user unlocking method, comprising:

receiving an input speech signal;

determining sound feature parameters of the input speech signal according to the speech signal;

logging into a primary user account upon determining that the sound feature parameters are consistent with primary user sound feature parameters pre-stored by a terminal device; and

logging into a guest account upon determining that the sound feature parameters are not consistent with the primary user sound feature parameters pre-stored by the terminal device.

2. The method according to claim 1, wherein after the input speech signal is received, the method further comprises:

determining speech contents of the input speech signal according to the speech signal;

logging into the primary user account upon determining that the sound feature parameters are consistent with the primary user sound feature parameters pre-stored by the terminal device comprises;

logging into the primary user account upon determining that the sound feature parameters are consistent with the primary user sound feature parameters pre-stored by the terminal device, and that the speech contents are consistent with unlocking speech contents pre-stored by the terminal device; and

logging into the guest account upon determining that the sound feature parameters are not consistent with the primary user sound feature parameters pre-stored by the terminal device, and that the speech contents are consistent with the unlocking speech contents pre-stored by the terminal device.

3. The method according to claim 2, wherein before the input speech signal is received, the method comprises:

receiving at least one input sample speech signal; and

parsing the at least one input sample speech signal for speech contents and sound feature parameters, and storing the speech contents and sound feature parameters

4. The method according to claim 2, wherein the determining that the speech contents of the speech signal are consistent with the speech contents pre-stored by the terminal device comprises:

retrieving the speech contents pre-stored by the terminal device; and

determining whether the speech contents of the speech signal are consistent with the speech contents pre-stored by the terminal device.

5. The method according to claim 1, wherein the determining that the sound feature parameters of the unlocking speech signal are not consistent with the primary user sound feature parameters pre-stored by the terminal device comprises:

retrieving the primary user sound feature parameters pre-stored by the terminal device; and

determining whether the sound feature parameters of the speech signal are consistent with the primary user sound feature parameters pre-stored by the terminal device.

6. The method according to claim 2, wherein the method further comprises:

if it is determined that the speech contents of the speech signal are not consistent with the speech contents pre-stored by the terminal device, then determining a failure with unlocking.
