A control method, applicable to a master headset and a slave headset that are connected to an electronic device, wherein the master headset directly communicates with the electronic device, the slave headset communicates with the electronic device through the master headset, and the control method comprises the following steps: detecting, by the master headset, a first voice; automatically collecting, by the master headset, the first voice in response to the detected first voice; determining, by the master headset, whether the master headset has a talk right (S104a); if the master headset has the talk right, uploading, by the master headset, the first voice to the electronic device; receiving, by the slave headset, a first translation result through the master headset, and playing the first translation result, wherein the first translation result is a result obtained by the electronic device by automatically translating the first voice according to a setting for mutual translation between languages; if the master headset does not have the talk right, deleting, by the master headset, the first voice; detecting, by the slave headset, a second voice; automatically collecting, by the slave headset, the second voice in response to the detected second voice; uploading, by the slave headset, the second voice to the master headset and buffering, by the master headset, the second voice; applying, by the slave headset, for the talk right from the master headset, wherein such applying step is used to prompt the master headset to determine whether the slave headset has the talk right; if the slave headset has the talk right, uploading, by the master headset, the second voice to the electronic device; receiving, by the master headset, a second translation result, wherein the second translation result is a result obtained by the electronic device by automatically translating the second voice according to the setting for mutual translation between languages; if the slave headset does not have the talk right, deleting, by the master headset, the second voice; wherein, when the master headset has the talk right, the slave headset does not have the talk right, and when the slave headset has the talk right, the master headset does not have the talk right. detecting, by the master headset, a first voice; automatically collecting, by the master headset, the first voice in response to the detected first voice; determining, by the master headset, whether the master headset has a talk right (S104a); if the master headset has the talk right, uploading, by the master headset, the first voice to the electronic device; receiving, by the slave headset, a first translation result through the master headset, and playing the first translation result, wherein the first translation result is a result obtained by the electronic device by automatically translating the first voice according to a setting for mutual translation between languages; if the master headset does not have the talk right, deleting, by the master headset, the first voice; detecting, by the slave headset, a second voice; automatically collecting, by the slave headset, the second voice in response to the detected second voice; uploading, by the slave headset, the second voice to the master headset and buffering, by the master headset, the second voice; applying, by the slave headset, for the talk right from the master headset, wherein such applying step is used to prompt the master headset to determine whether the slave headset has the talk right; if the slave headset has the talk right, uploading, by the master headset, the second voice to the electronic device; receiving, by the master headset, a second translation result, wherein the second translation result is a result obtained by the electronic device by automatically translating the second voice according to the setting for mutual translation between languages; if the slave headset does not have the talk right, deleting, by the master headset, the second voice; wherein, when the master headset has the talk right, the slave headset does not have the talk right, and when the slave headset has the talk right, the master headset does not have the talk right.
