Spanish voice command recognition

Since voice detection varies by language, recognition algorithms are inherently sensitive to language-specific phonetics. In this context, we introduce a dataset in Spanish for controlling a robotic arm. The dataset consists of 20 folders, one for each worker or speaker. Inside each folder, there are 30 WAV audio files. Each file is identified by four pairs of numbers XX-XX-XX-XX.wav. The first pair designates the worker as 01 through 20, and the second pair denotes the gender, using 01 for male and 02 for female. The third pair specifies the speaker's emotion: 01 for angry, 02 for neutral, and 03 for sad. Finally, the fourth pair identifies the voice command in Spanish used to control a robotic arm with a gripper or End-of-Arm Tooling (EOAT). The commands are: 01 Move up (Desplázate hacia arriba), 02 Move down (Desplázate hacia abajo), 03 Move forward (Muévete hacia adelante), 04 Move backward (Muévete hacia atrás), 05 Turn right (Gira a tu derecha), 06 Turn left (Gira a tu izquierda), 07 Open the gripper (Abre la pinza), 08 Close the gripper (Cierra la pinza), 09 Move to start pose (Muévete al origen), and 10 Wait (Para ahí).
