Voice Dataset Annotation

Accuracy between 95%~98%

Surfing Tech applies its own algorithm during speech dataset annotation to ensure high efficiency and accuracy. We achieve above 95% accuracy rate after three rounds of quality inspection, which makes the audio datasets more valuable for speech emotion recognition dataset, semantic understanding, and human-computer interaction.
