Listen only to me! How well can target speech extraction handle false alarms?
Strong paper for false-alarm handling in TSE, wrong domain if someone tries to count it as SSI progress.
Reading guidance
- Verdict
- full-text draft · priority medium · confidence high
- Why it matters
- As a TSE paper, the full text is strong: the verification route keeps extraction quality closer to baseline while materially reducing false alarms, but it is still not an SSI paper.
- What to trust
- Basis: full text. Coverage: high. 4 evidence records back the review.
- What is weak
- Everything is benchmarked on LibriMix mixtures; there is no silent-speech modality or multimodal cue. The evidence is specific to the SpeakerBeam family and the LibriMix training recipe reported here. TSE-V needs an extra verification stage and enrollment audio, and none of it addresses SSI interaction. Target speech extraction with inactive-speaker handling only. Overclaim risk: Any claim that this is an SSI advance would be unsupported by the full text..

Expert take
Table 2 shows the tradeoff clearly. TSE-IS can directly output zeros, but at 10-second enrollment it drops to 10.8 dB SDRi before detection, 8.6% failure, 11.6% EER, and 13.4% fail-and-miss. TSE-V(360) is the better operating point: 13.6 dB SDRi before detection, 1.7% failure, 6.3% EER, and 7.1% fail-and-miss. Figure 4 sharpens the practical lesson: longer enrollment helps TSE-V approach roughly 5% EER around 15 to 20 seconds. That is a credible deployment result for TSE, but it has no silent-speech sensing or articulatory interface component.
True value
As a TSE paper, the full text is strong: the verification route keeps extraction quality closer to baseline while materially reducing false alarms, but it is still not an SSI paper.
What changed
Canon before
Target speech extraction papers usually assumed the enrolled speaker was always active, which hides false alarms at deployment time.
Delta from canon
This paper makes inactive-speaker failure a first-class evaluation target and shows that verification-based handling is stronger than direct zero-output training.
Position in field
Useful deployment-failure analysis for target speech extraction, outside the core SSI modality set.
