| Title | Masking Speech Contents by Random Splicing: is Emotional Expression Preserved? |
| Abstract | We discuss the influence of random splicing on the perception of emotional expression in speech signals. Random splicing is the randomized reconstruction of short audio snippets with the aim to obfuscate the speech contents. A part of the German parliament recordings has been random spliced and both versions – the original and the scrambled ones – manually labeled with respect to the arousal, valence and dominance dimensions. Additionally, we run a state-of-the-art transformer-based pre-trained emotional model on the data. We find sufficiently high correlation for the annotations and predictions of emotional dimensions between both sample versions to be confident that machine learners can be trained with random spliced data. |
