A method to acquire the signal of the vocal cords' vibrations was developed and presented. It is a non-invasive method that is based on attaching a transducer element to a collar and wrapping it around the individual's neck. The Short Term Fourier Transform (STFT) technique is applied on the collected signal to decompose it into its frequency contents. The features defined in terms of a range of frequencies are extracted for speaker identification purposes. The position of the transducer on the human's neck could affect the quality of the collected signal and consequently, the extracted features. Therefore, the study of the effect of the transducer's location is in accordance. In this context, the mediums through which the vocal cords' vibrations are propagated until their detection by the transducer are modeled. Subsequently, numerical simulation experiments are performed to determine the best location on the human's neck for transmission purposes.
