Voice transmission device and method for executing voice assistant program thereof

A voice transmission device for establishing a connection with an electronic device having at least a first voice assistant program and a second voice assistant program, the voice transmission device comprising:

• a microphone, used for receiving a voice signal;
• a detection module, used for detecting whether the second voice assistant program of the electronic device is activated;
• wherein when detecting that the second voice assistant program is not activated, a first flag is generated;
• when detecting that the second voice assistant program is activated, a second flag is generated;
• a memory module, electrically connected to the detection module for storing the first flag or the second flag;
• and
• a control switch, electrically connected to the memory module to read the memory module for a user's operation, wherein when the memory module stores the first flag, the control switch generates a first control signal by the user's operation to allow the electronic device to execute the first voice assistant program for recognizing the voice signal;
• when the memory module stores the second flag, the control switch generates a second control signal by the user's operation to allow the electronic device to execute the second voice assistant program for recognizing the voice signal.
