Extracting direct-path spatial feature is crucial for sound source localization in adverse acoustic environments. This paper proposes IPDnet, a neural network that estimates direct-path inter-channel phase difference (DP-IPD) of sound sources from microphone array signals. The estimated DP-IPD can be easily translated to source location based on the known microphone array geometry. First, a full-band and narrow-band fusion network is adopted for DP-IPD estimation, in which combined narrow-band and full-band layers are responsible for estimating the raw DP-IPD information in one frequency band and capturing the frequency correlations of DP-IPD, respectively. Second, a new multi-track DP-IPD learning target is proposed for the localization of a flexible number of sound sources. Third, the network is extended to handle variable microphone arrays. This version of IPDnet is trained with a large set of different microphone arrays, and then it is able to infer the source locations using new microphone arrays not seen at training time. Experiments with multiple number of moving speakers are conducted on both simulated and real-world data, which show that the full-band and narrow-band fusion network and the proposed multi-track DP-IPD learning target together achieve excellent sound source localization performance. Moreover, the proposed variable-array model generalizes well to unseen microphone arrays.

In this paper, we propose an explanation of representation for self-attention network (SAN) based neural sequence encoders, which regards the information captured by the model and the encoding of the model as graph structure and the generation of these graph structures respectively. The proposed explanation applies to existing works on SAN-based models and can explain the relationship among the ability to capture the structural or linguistic information, depth of model, and length of sentence, and can also be extended to other models such as recurrent neural network based models. We also propose a revisited multigraph called Multi-order-Graph (MoG) based on our explanation to model the graph structures in the SAN-based model as subgraphs in MoG and convert the encoding of the SAN-based model to the generation of MoG. Based on our explanation, we further introduce an MO-Transformer by enhancing the ability to capture multiple subgraphs of different orders and focusing on subgraphs of high orders. Experimental results on multiple neural machine translation tasks show that the MO-Transformer can yield effective performance improvement.

Audio bandwidth extension involves the realistic reconstruction of high-frequency spectra from bandlimited observations. In cases where the lowpass degradation is unknown, such as in restoring historical audio recordings, this becomes a blind problem. This paper introduces a novel method called BABE (Blind Audio Bandwidth Extension) that addresses the blind problem in a zero-shot setting, leveraging the generative priors of a pre-trained unconditional diffusion model. During the inference process, BABE utilizes a generalized version of diffusion posterior sampling, where the degradation operator is unknown but parametrized and inferred iteratively. The performance of the proposed method is evaluated using objective and subjective metrics, and the results show that BABE surpasses state-of-the-art blind bandwidth extension baselines and achieves competitive performance compared to informed methods when tested with synthetic data. Moreover, BABE exhibits robust generalization capabilities when enhancing real historical recordings, effectively reconstructing the missing high-frequency content while maintaining coherence with the original recording. Subjective preference tests confirm that BABE significantly improves the audio quality of historical music recordings. Examples of historical recordings restored with the proposed method are available on the companion webpage: http://research.spa.aalto.fi/publications/papers/ieee-taslp-babe/

This paper proposes an online target speaker voice activity detection (TS-VAD) system for speaker diarization tasks that does not rely on prior knowledge from clustering-based diarization systems to obtain target speaker embeddings. By adapting conventional TS-VAD for real-time operation, our framework identifies speaker activities using self-generated embeddings, ensuring consistent performance and avoiding permutation inconsistencies during inference. In the inference phase, we employ a front-end model to extract frame-level speaker embeddings for each incoming signal block. Subsequently, we predict each speaker's detection state based on these frame-level embeddings and the previously estimated target speaker embeddings. The target speaker embeddings are then updated by aggregating the frame-level embeddings according to the current block's predictions. Our model predicts results block-by-block and iteratively updates target speaker embeddings until reaching the end of the signal. Experimental results demonstrate that the proposed method outperforms offline clustering-based diarization systems on the DIHARD III and AliMeeting datasets. Additionally, this approach is extended to multi-channel data, achieving comparable performance to state-of-the-art offline diarization systems.

It is difficult to achieve robust and well-generalized models for tasks involving subjective concepts such as emotion. It is inevitable to deal with noisy labels, given the ambiguous nature of human perception. Methodologies relying on semi-supervised learning
