e-REAL Speech Analysis is a powerful training tool to individually track both the tone of voice and spoken words of the learners, providing a semantic and pragmatic overview of interpersonal communication. According to the Polytechnic School of Turin and to ISTI-CNR (a branch from the Italian Research Council), the fidelity of a speech recording and transcription is approximately 94%. An operator such as a simulation engineer may be able to amend and modify the transcript so that its fidelity achieves 100% semantic accuracy.

Functions and visual outputs include the following:

• An integral transcript or dialogue which can be visualized
• Audio clips, automatically divided phrase by phrase
• A word counter which shows the number of spoken words per minute
• An internal search engine with keyword search enabled, highlighting the words in the transcript
• A word cloud tool visually summarizing the most spoken words
• A Voice Analysis tool to measure and visualize waveform (Decibel), perceived loudness (Hertz) and pitch.
