Spoken language identification (LID) has seen substantial performance gains with the rise of large-scale models. However, these models are often computationally expensive and impractical for many real-world applications. In this work, we propose a novel knowledge distillation from ensemble framework…
Automatic age estimation from speech has a variety of applications including natural human-computer interaction, targeted advertising, customer-agent pairing in call centers, and forensics, to mention a few. Recently, the use of i-vectors has shown promise for automatic age estimation. In this paper…
Many state-of-the-art speaker recognition engines use i-vectors to represent variable-length acoustic signals in a fixed low-dimensional total variability subspace. While such systems perform well under seen channel conditions, their performance greatly degrades under unseen channel scenarios. Accor…
Many state-of-the-art i-vector based voice biometric systems use linear discriminant analysis (LDA) as a post-processing stage to increase the computational efficiency in the back-end via dimensionality reduction, as well as annihilate the undesired (noisy) directions in the total variability subspa…
