Speech-Hands: A Self-Reflection Voice Agentic Approach to Speech Recognition and Audio Reasoning with Omni Perception
This research introduces a groundbreaking voice-agentic framework, Speech-Hands, that equips omni-modal models with a critical self-reflection skill: knowing when to trust their own perception versus when to consult external audio inputs or expert tools. It addresses a fundamental flaw in current omni-models, which can be misled by noisy hypotheses, leading to performance degradation.

The Core Self-Reflection Mechanism
Speech-Hands introduces explicit action tokens (<internal>, <external>, <rewrite>) to allow the model to dynamically orchestrate its cognitive strategy. This prevents the model from being misled by flawed external candidates, a common issue in naive multimodal fusion. This agentic approach allows for intelligent arbitration between internal perception and external advice.
Unlike egocentric models that implicitly trust internal perception, Speech-Hands actively decides when to rely on its own auditory interpretation, when to defer to an external expert (e.g., another ASR system), or when to initiate a rewrite for deeper reasoning. This learnable primitive is crucial for overcoming issues like external-induced misguidance and overcorrection.

Mitigating Model Confusion
Preliminary experiments showed that simply fine-tuning an omni-model on combined speech recognition and sound understanding tasks often degraded performance. This was due to the model struggling to resolve conflicts between its own perception and potentially flawed external suggestions. Speech-Hands addresses this by providing a principled mechanism for arbitration, as demonstrated by improved performance across benchmarks.
ASR Performance Gains
Speech-Hands significantly outperforms strong baselines in Automatic Speech Recognition (ASR), achieving notable WER reductions across diverse datasets. This is critical for enterprise applications like transcription services, call center analytics, and voice assistants, where accuracy directly impacts operational efficiency and user satisfaction.

Comparative ASR Results (WER %)
| Model / Setting | AMI | Tedlium | Gigaspeech | Avg. WER ↓ |
|---|---|---|---|---|
| Whisper-v2-large (Baseline) | 16.88 | 4.32 | 11.45 | 7.17 |
| Qwen2.5-Omni (Baseline) | 19.77 | 5.17 | 11.26 | 7.33 |
| GER: Whisper-v2-large (Cascaded) | 23.44 | 6.15 | 12.15 | 8.44 |
| Speech-Hands + Canary | 15.29 | 4.21 | 10.87 | 6.17 |
| Speech-Hands + Parakeet | 11.20 | 4.37 | 11.10 | 5.69 |
The explicit control via action tokens in Speech-Hands leads to significant performance improvements compared to naive prompting or cascaded GER setups, demonstrating its stability and transferability even with limited training data.
Audio QA Robustness
Speech-Hands achieves superior accuracy and F1 scores on complex audio question-answering tasks, showcasing its ability to handle abstract reasoning and fine-grained audio patterns. This reliability is vital for applications requiring deep contextual understanding of audio, such as surveillance, content moderation, or accessibility tools.

Enhanced Decision-Making in Audio QA
The framework's ability to self-reflect and choose the most reliable source of information minimizes errors like external-induced misguidance, where the model is led astray by flawed external hypotheses. This ensures that critical decisions derived from audio analysis are robust and accurate.
Case Study: Audio QA (Section 6.3 / Appendix F)
Scenario: An audio clip plays. Q. Based on the audio, which natural phenomenon could be occurring? Options: A. Earthquake B. Thunderstorm C. Forest fire D. Snowstorm
Internal pred: B. Thunderstorm
External pred: B. Thunderstorm
Speech-Hands Prediction: <rewrite> C. Forest fire (✔)
Analysis: Both internal and external models incorrectly predicted "Thunderstorm", likely influenced by surface acoustic features. Speech-Hands, by electing to <rewrite>, correctly identifies "Forest fire", demonstrating its capacity to overcome consensus errors and align with the ground truth through deeper reasoning.
Tool-Augmented Perception
Beyond self-reflection on internal and external hypotheses, Speech-Hands can integrate Active Perception via Digital Signal Processing (DSP) tools. This allows the model to "clean its ears" before transcription or reasoning, mitigating issues stemming from intrinsic audio degradation like background noise or poor microphone quality.
Impact of Active Tools (WER / Accuracy)
| Metric/Dataset | Standard (Passive) | w/ Active Tools (BNR + Studio) |
|---|---|---|
| Speech Recognition (AMI) | 15.03 | 13.41 (-1.62) |
| Audio Reasoning (Soundscape QA) | 59.40 | 63.15 (+3.75) |
This demonstrates that for highly degraded inputs, agentic reasoning should precede perception, deciding how to listen is as important as deciding what was heard. Integrating tools like Background Noise Removal (BNR) and Studio Voice Restoration significantly improves performance on noise-sensitive tasks.
