**TESS Dataset**

The first dataset chosen for this mini-project is the TESS (Toronto emotional speech set) dataset. It contains 2880 files. A set of 200 target words were spoken in the carrier phrase "Say the word _' by two actresses and the sets were recorded in seven different emotions (anger, disgust, fear, happiness, pleasant surprise, sadness, and neutral). Both actresses spoke English as their first language, were university educated, and had musical training. Audiometric testing indicated that both actresses had thresholds within the normal range.

**Ravdess Dataset**

The second dataset chosen for this mini-project is Ravdess (The Ryerson Audio-Visual Database of Emotional Speech and Song). This dataset contains 1440 files: 60 trials per actor x 24 actors = 1440. The RAVDESS contains 24 professional actors (12 female, 12 male), vocalizing two lexically-matched statements in a neutral North American accent. Speech emotions includes calm, happy, sad, angry, fearful, surprise, and disgust expressions. Each expression is produced at two levels of emotional intensity (normal, strong), with an additional neutral expression.

**File naming convention**

Each of the 1440 files has a unique filename. The file name consists of a 7-part numerical identifier (e.g., 03-01-06-01-02-01-12.wav). These identifiers define the stimulus characteristics:

**Filename identifiers**

Modality (01 = full-AV, 02 = video-only, 03 = audio-only). Vocal channel (01 = speech, 02 = song). Emotion (01 = neutral, 02 = calm, 03 = happy, 04 = sad, 05 = angry, 06 = fearful, 07 = disgust, 08 = surprised). Emotional intensity (01 = normal, 02 = strong). NOTE: There is no strong intensity for the 'neutral' emotion. Statement (01 = "Kids are talking by the door", 02 = "Dogs are sitting by the door"). Repetition (01 = 1st repetition, 02 = 2nd repetition). Actor (01 to 24. Odd numbered actors are male, even numbered actors are female). Filename example: 03-01-06-01-02-01-12.wav

- Audio-only - 03
- Speech - 01
- Fearful - 06
- Normal intensity - 01
- Statement "dogs" - 02
- 1st Repetition - 01
- 12th Actor - 12 Female, as the actor ID number is even.
