The Importance of Inner Speaking in Improving the Student Actors’ Emotional Impact of the Voice

The process of inner speaking, often referred to as self-talk or inner monologue, holds significant importance in the artistic expression of young student actors during their early and inexperienced new performances. This paper draws upon various studies and employs three distinct techniques to elucidate the underlying mechanisms of inner speaking's role in emotional expression and highlights its implications for a young student actor's training and performance enhancement. The first method involves the utilization of magnetic resonance imaging (MRI) to observe the oxygenated parts of the brain that are associated with emotional discharge. This approach is conducted by a team of medical imaging specialists and utilizes a 3.0 T Signa Pioneer MRI scanner. The second method employs the use of a convolutional neural network with fully connected layers that have been trained using Mel-frequency cepstral coefficients (MFCCs) of the input audio files. This technique is used to capture the strength of emotion expressed in the speech of student actors on the first day of training relative to the final day of trial. The third and final method is spectral analysis, which plots the spectrograms at the first and last days of training and compares the spectrum of the recordings. Then the extracted results of this analysis are continued comparing.
