An electronic device for performing speech recognition, the electronic device comprising:

• a microphone configured to receive first and second speech signals;
• and
• at least one processor configured to:
• detect a first text, which is preset for performing speaker recognition, by performing speech recognition on the first speech signal,
• perform speaker recognition on the second speech signal acquired after the first speech signal, based on the first text being detected, and
• execute a voice command obtained from the second speech signal, based on a result of performing the speaker recognition on the second speech signal indicating that a speaker of the second speech signal corresponds to a first speaker who registered the first text.

A computer program product comprising a non-transitory computer readable recording medium having recorded thereon a plurality of instructions, which when executed by at least one processor, instruct the at least one processor to perform:

• detecting a first text, which is preset for performing speaker recognition, by performing speech recognition on a first speech signal;
• performing speaker recognition on a second speech signal acquired after the first speech signal, based on the first text being detected;
• and
