Summary

VieSpeaker is a new large-scale Vietnamese speaker recognition dataset, addressing the current scarcity of high-quality, acoustically diverse resources for the language. Unlike most existing large datasets that rely on visual cues for speaker identity, VieSpeaker employs a novel face-independent construction pipeline. This approach utilizes textual metadata and large language model reasoning to infer speaker identities from transcripts and contextual information, eliminating the need for on-camera recordings. The dataset comprises approximately 902 hours of speech from 4,715 distinct speakers. Experiments demonstrate that models trained on VieSpeaker achieve improved robustness and generalization capabilities compared to those trained on previously available Vietnamese datasets, showcasing the viability of face-independent data collection for speech resources.

Key takeaway

For machine learning engineers developing speaker recognition systems for Vietnamese or other under-resourced languages, you should consider adopting face-independent data collection methods. This approach, demonstrated by VieSpeaker, allows for significantly larger and more acoustically diverse datasets by inferring speaker identities from textual metadata and LLM reasoning, rather than relying on visual cues. Integrating such datasets can improve your model's robustness and generalization, offering a path to overcome data scarcity challenges without the constraints of video recordings.

Key insights

Face-independent dataset construction using textual metadata and LLM reasoning enables large-scale speaker recognition resources for under-resourced languages.

Principles

• Speaker identity inference can be achieved without visual cues.
• Textual metadata and LLM reasoning enable face-independent data.
