Two people singing in time, at the same volume and and on the same note still have different sounds. If phase, frequency and amplitude are the same, what makes them sound different?

Science Teacher, you are right of course, but what I'm looking for is what characteristic of the wave makes people's voices different. Can you expand on your answer?

The sound waves have frequency, amplitude and shape.
Two sounds with same frequency and amplitude will sound differently if they have different shape for example sin wave sounds different than triangle wave. The shape is actually composition of several frequencies (see Fourier transformation). Human voice is also changing in time and the shape and frequency changes and the way they change differ from one person to another

The thicknss of their vocal cords and the resonance area of their throat affect the tone quality an make each voice unique. 2 people can sing the same pitch, but where does it fall in the range for each? Timbre is a musical term for uniqueness of sound.
